The WMW identified a set of 18 separate surface water modeling applications that are currently applied to support development of Total Maximum Daily Load (TMDL) plans, assess permit conditions for National Pollutant Discharge Elimination System (NPDES) facilities, evaluate policy and water quality effects of potential actions, and conduct other water quality analyses. The WMW directed Tetra Tech to perform an assessment of the current maintenance and support status of each modeling tool to facilitate the identification of gaps in support or other activities that might warrant future WMW activity. This report summarizes the findings of Tetra Tech's review of the maintenance and support status of the following modeling applications. AGNPS BATHTUB CORMIX HSPF SPARROW SWTOOLBOX Aquatox CE-QUAL-ICM EFDC LSPC SWAT VISUAL PLUMES BASINS CE-QUAL-W2 HAWQS QUAL2KW SWMM WASP 1 ------- AG N PS/AN NAG N PS Agricultural Nonpoint Source Pollution Model (AGNPS) is a modeling tool for use in evaluating the effect of predominantly agricultural management decisions impacting water, sediment and chemical loadings within a watershed system. The model predicts (1) water; (2) sediment by particle size class & source of erosion; and (3) chemicals-nitrogen, phosphorus, organic carbon, & pesticides. The pollutant loadings are generated from land areas and routed through stream systems on a daily basis. Special land use components such as feedlots, gullies, field ponds, and point sources are included. MODEL DEVELOPER/STEWARD AGNPS was developed by the United States Department of Agriculture (USDA) Agricultural Research Service (ARS). USDA continues to provide support for the model. Ron Bingner is the ARS project manager responsible for the distribution of AGNPS. Ron Binger can be contacted at Ron.Bingerffiars.usda.gov or (662)232-2966. MODEL STATUS The model name "AGNPS" has been replaced with Annualized AGNPS (AnnAGNPS) and refers to a system of model components which can be used to estimate annualized loads and load reductions. The single event version known as AGNPS was discontinued in the mid-1990's. Several versions that integrate the model with geographic information system (GIS) and Windows-based graphical user interfaces are available. The most recent version of AnnAGNPS (version 5.45) is dated December 2016. AnnAGNPS versions 5.0 and later incorporate enhanced features for many input and output options including ephemeral gullies, automated calibration for pollutants, actual or potential evapotranspiration climate files, and the ability to enter unlimited climate stations with any naming convention. MODEL CODE AnnAGNPS is a batch-process, continuous-simulation, surface-runoff, pollutant loading computer model written in standard ANSI FORTRAN 2015. SOURCE CODE The model (current version 5.45) is a non-proprietary, public domain model with an open source code that can be accessed and downloaded by any individual at the following web site: https://www.nrcs.usda.gov/wps/portal/nrcs/detailfull/national/water/manage/hvdrology/?cid=stelprdbl043591 ACCESSIBILITY USER COMMUNITY PORTAL There is no user community portal.

The aquatic ecosystems that can be modeled include streams, rivers, lakes, reservoirs and estuaries. Hydrodynamics are not simulated within AQUATOX and must be supplied as model inputs. AQUATOX predicts the response of these aquatic ecosystems to multiple stressors including nutrients, organic loadings, sediments, organic chemicals and temperature. AQUATOX is known as a process-based or mechanistic model because it simulates the transfer of biomass, energy and chemicals from one compartment of the ecosystem to another by simultaneously computing each of the most important chemical or biological processes.AQUATOX can be run as a point model, a stratified model (for lakes), and as a two- or three-dimensional model with linked segments depending on the modeling goal. MODEL DEVELOPER/STEWARD Lead developer(s) and affiliation: Richard Park of Eco Modeling and Jonathan Clough of Warren Pinnacle Consulting Inc. developed AQUATOX for U.S. Environmental Protection Agency (EPA) Office of Water. Maintenance Status: AQUATOX is maintained by EPA Center for Exposure Assessment Modeling (CEAM). VERSION INFORMATION AQUATOX was developed in 2002 and has undergone major updates since the initial release, as summarized in Table 1. The model was developed and compiled in Delphi.

It applies a series of eutrophication models derived from lake monitoring data from a number of northeastern U.S. lakes to perform steady-state water and nutrient balance calculations that account for advective and diffusive transport, and nutrient sedimentation, as well as internal pollutant sources. Eutrophication-related water quality conditions are predicted by BATHTUB and expressed as total phosphorus, total nitrogen, chlorophyll a, transparency, organic nitrogen, ortho-phosphorus, and hypolimnetic oxygen depletion rate. BATHTUB can be configured for simultaneous application to collections or networks of reservoirs to provide regional perspectives on reservoir water quality.

RELEVANT LINKS http://www.wwwalker.net/bathtub/help/bathtubWebMain.html 15 ------- CE-QUAL-ICM CE-QUAL-ICM was first developed by the U.S. Army Corps of Engineers' Engineer Research and Development Center (ERDC) as a three-dimensional eutrophication model for Chesapeake Bay and its major tributaries. It continues to be applied for eutrophication studies in rivers, lakes, reservoirs, estuaries and coastal areas around the world. It is capable of simulating biogeochemical cycles, including the aquatic carbon cycle, nitrogen cycle, phosphorus cycle and oxygen cycle as well as physical factors, including salinity, temperature and suspended solids. It does not simulate hydrodynamics. Its technical underpinning is analogous to the finite-volume numerical method and the model simulates the transport and fate of pollutants in well-mixed cells that can be arranged in 1-, 2-, or 3-dimensional configurations. Simulated constituents include algae, carbon, nitrogen, phosphorus, silica, dissolved oxygen, zooplankton, submerged aquatic vegetation, epiphytes, and benthic algae.

TRAINING MATERIALS none 18 ------- CE-QUAL-W2 CE-QUAL-W2, commonly referred to as W2, is a 2-dimensional (vertical/longitudinal) hydrodynamic and water quality model. It is configured as a user defined grid and its mathematical structure is based on a set of differential equations that define conservation of mass and energy in each horizontal layer. The model includes variable cell spacing allowing for greater resolution where needed with simulation algorithms based on hydrostatic approximation (i.e. negligible vertical accelerations) and eddy coefficients used to simulate turbulence. Also included are numerical algorithms for pipe, weir, spillways, and pump flow. Simulated water quality includes nutrients, eutrophication kinetics, and a single algal compartment. General quality constituents can also be simulated using user-defined decay rates, settling rates, and temperature correction coefficients. It is best suited for long, narrow rivers, lakes, reservoirs and estuaries because it assumes lateral homogeneity. MODEL DEVELOPER/STEWARD LEAD DEVELOPER(S) AND AFFILIATION Thomas Cole, of the U.S. Army Corps of Engineers (USACE) originally developed W2 and the Corps provided early maintenance and development support for W2. While they have done so in the past, presently, the Corps does not provide support for model maintenance. Dr. Scott Wells, director of the Water Quality Research Group (WQRG) at Portland State University (PSU) continues to maintain the code internally at PSU. The work is supported by research grants and CE-QUAL-W2 training contracts (personal communication). Dr. Wells indicated that his group has received additional funds beginning in fall 2018 (with further funding anticipated) to continue updating and maintaining the code for the Corps. MAINTENANCE STATUS AND FUNDING SOURCE A fact sheet on the USACE webpage (undated, accessed 10/11/2017) is outdated, indicating the current version of W2 is 3.71. The current version is version 4.1. It was released October 3, 2017. PSU provides the newest version of W2 on their web page, which notes that they do not receive support from USACE for model support, maintenance or upgrades. Contributions are accepted on the webpage to help support continued model maintenance, bug fixes and updates. MODEL STATUS All available versions of W2 are non-proprietary and the source code is publicly available. CURRENT MODEL VERSION AND YEAR OF RELEASE The current version is 4.1 (October 3, 2017), available here, includes a registration page, download of source code, model release notes, executable, User Manual, documentation, example problems and reports. OTHER MODEL VERSIONS Older versions of W2 including versions 3.1, 3.2, 3.5, 3.6, and 3.7 are also available on the PSU model webpage; however they are no longer actively supported. The download packages are similar to version 4.1. The 'History' link on the model webpage provides a detailed description of the differences between all versions of W2.

(2013) 21 ------- CORMIX CORMIX is a mixing zone model and decision support system for environmental impact assessment of regulatory mixing zones resulting from continuous point source discharges. The system emphasizes the role of boundary interaction to predict steady-state mixing behavior and plume geometry. CORMIX contains systems to model discharges where initial mixing zone characteristics are desired. Discharge types that can be modeled include power plant cooling waters, desalinization facility or drilling rig brines, and municipal wastewater. The effluents considered may be conservative, non-conservative, heated, brine discharges or contain suspended sediments. CORMIX can be applied across a variety of waterbodies ranging from estuaries, deep oceans, rivers, to stratified reservoirs and lakes. CORMIX makes near-field and far-field plume trajectory, shape, concentration, and dilution predictions and visualizations within these waterbodies. MODEL DEVELOPER/STEWARD CORMIX development began in 1986 with Dr. Robert Doneker at Cornell University under a contract with the U.S. Environmental Protection Agency (Environmental Research Laboratory, Athens, GA; Dr. Thomas Barnwell, Program Officer). CORMIX is no longer distributed or supported by the U.S. EPA. Information on a Windows version of CORMIX is available at cormix.info. CORMIX software is licensed and distributed solely by MixZon Inc. Contact MixZon Inc. or Dr. Robert Doneker (donekerffiese.ogi.edu) of Oregon Graduate Institute (OGI) Department of Environmental Science and Engineering for technical information and support.

Model simulations can be fully coupled where hydrodynamics, sediment, and contaminant transport are executed simultaneously or be done using saved hydrodynamic transport data. EFDC can represent water bodies in one, two and three dimensions using a finite difference methodology. Model cells are represented using a curvilinear or Cartesian grid with two options for vertical cell spacing: Sigma-z or GVC (general vertical coordinate). Water column transport includes 3-dimensional advection and vertical and horizontal turbulent diffusions. EFDC also incorporates a eutrophication water quality model, functionally equivalent to CE-QUAL-ICM and can represent multiple size classes of cohesive and non- cohesive sediments, associated deposition and resuspension processes, and bed geomechanics. Toxics are transported as both dissolved and sediment associated in the water column and bed. Other model features include representation of drying and wetting, hydraulic structures, vegetation resistance, and Lagrangian particle tracking. MODEL DEVELOPER/STEWARD Lead developer(s) and affiliation: The late Dr. John Hamrick originally developed EFDC while at the Virginia Institute of Marine Science, funded with state legislatively directed research funds. Further support was provided by the U.S. Environmental Protection Agency and the National Oceanic and Atmospheric Administration's Sea Grant Program. After Dr. Hamrick joined in the 1990's, Tetra Tech has been a major focus for continued development of EFDCboth from continued EPA funding as well as through a variety of additional projects throughout the country. Tetra Tech continues to support the use and enhancement of EFDC through individual, project-specific customizations. Maintenance status: There is no current federally supported program to maintain, support or enhance the model. Project- and client- specific efforts to customize the model have resulted in multiple customized versions developed by various entities among government, academia and consulting firms. Funding source: None ongoing for the EPA version of EFDC. VERSION INFORMATION For purposes of this summary, the publicly available, EPA version of EFDC will be referred to as EPA-EFDC. Other entities have also developed versions of EFDC based on the 2007 EPA-EFDC. These versions are technically "newer" versions and have undergone various customizations, sometimes significant, depending on specific program needs. For example, the Philadelphia Water Department maintains its own version of EFDC, which was based on the 2007 EPA-EFDC version but has been significantly customized to support the needs of the department. Likewise, the St. Johns Water Management District in Florida also maintains a version of EFDC for the St. Johns River. Sandia National Laboratories1 developed SNL-EFDC, an open-source tool to support the marine renewable-energy industry by enabling simultaneous evaluation of array power production and environmental effects. They 1 Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC., a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Department of Energy's National Nuclear Security Administration. 25 ------- subsequently incorporated the module into an open-source version of the DELFT-3D application called SNL-DELFT- 3d-CEC. Dynamic Solutions-International (DSI), developed a Windows-based GUI (interface) for pre- and post-processing of the Environmental Fluid Dynamics Code (EFDC). The interface is commercially known as EFDC-Explorer and their version of the EFDC model is called EFDCPIus. DSI's version of EFDC includes a multi-thread function as well as new variables such as C02. DSI's website provides links for downloading EFDC_Plus as well as the EPA-EFDC version. The user must register to download all files from the website. EFDCPIus, EFDC-Explorer and the grid generator are all proprietary. They provide the source code for only their single-thread version to licensees upon request. In recent years, Tetra Tech developed Visual EFDC (VEFDC), a user-graphical interface for creating and editing curvilinear orthogonal grids for EFDC as well as for creating and manipulating input data files and model output results. VEFDC is not open-source but Tetra Tech distributes the interface to clients and upon request. In addition to the above EFDC model versions and GUIs, other pre and post processing GUI tools for EFDC are commercially available (e.g., grid generation tools and post processing tools to support various graphics packages). Funding to support development of these tools has come from various sources so they are not all necessarily publicly available or their source code may not be available. The version history of EPA-EFDC and others is summarized in Table 8. All of the non-EPA versions are derived from the EPA version. Executables are presented in Table 9. Table 8.

HAWQS provides users with interactive web interfaces and maps; pre-loaded input data; SWAT outputs that include tables, charts, and raw output data; and online development, execution, and storage of a user's modeling projects. MODEL DEVELOPER/STEWARD The U. S. Environmental Protection Agency (EPA) Office of Water supports and provides project management and funding for HAWQS. The Texas A&M University Spatial Sciences Laboratory and EPA provide ongoing technical support including system design, modeling, and software development. MODEL STATUS HAWQS Version 1.0 is a non-proprietary modeling tool that was released in September 2017. Future versions will be released based on user needs. There are no previous versions. The model code language for the SWAT model within HAWQS is FORTRAN. ACCESSIBILITY HAWQS is run entirely on a server, therefore personal computing requirements are minimal. HAWQS requires a web browser, such as the latest version of Chrome, Firefox, or Safari, Internet Explorer 11 or Microsoft Edge. HAWQS can be accessed at epahawqs.tamu.edu/. SOURCE CODE The source code for the SWAT model used in HAWQS is available for download at swat.tamu,edu/software/swat- executables/. USER COMMUNITY PORTAL There is no HAWQS community portal. For assistance with account settings and system errors, users can contact eco.webffitamu.edu. For assistance with training and use cases, users can contact hawqs@epa.gov. DOCUMENTATION AND TRAINING MATERIALS MODELTHEORY DOCUMENTATION HAWQS does not have its own model theory documentation. All model theory documentation for the SWAT model can be found at swat.tamu.edu/documentation/. The documentation includes Soil and Water Assessment Tool Theoretical Documentation for SWAT versions 2000, 2005 and 2009 (Neitsch et al. 2002, 2005 and 2011). There is also Input/Output File Documentation for SWAT versions 2005, 2009 and 2012 (Neitsch et al. 2004 and 2011; Arnold et al. 2012). USER MANUAL The HAWQS vl.O User Guide was released in September 2017 and can be downloaded epahawqs.tamu.edu/.

For assistance with training, users can contact hawqs@epa.gov. 31 ------- HSPF The Hydrologic Simulation Program FORTRAN (HSPF) is a comprehensive model for the simulation of watershed hydrology and water quality for both conventional pollutants and toxic chemicals. It enables simulation of both land based runoff, temperature, and pollutant loading with instream hydraulic and pollutant fate and transport processes in 1-dimensional stream channels. Watershed hydrology simulations are based on the Stanford Watershed Model and consists of a water balance method that defines the water storage for surface and soil layers. Water storage is modified by interception, infiltration, evapotranspiration, and losses to inactive groundwater with outflows simulated from surface and subsurface (interflow and groundwater outflow) layers. Sediment is simulated as cohesive (silt and clay) and non-cohesive (sand) fractions with loading based on detachment/scour and transport algorithms. Other pollutant loads can be simulated generally using build-up washoff functions and instream transport and fate processes or using agricultural and eutrophication modules that explicitly represent the application, transformation, interaction, and fate of nutrients, phytoplankton, gases, pH, and pesticides. HSPF also includes a special action block for simulating management activities. MODEL DEVELOPER/STEWARD HSPF was originally developed by Crawford et al. (1966) as the Stanford Watershed Modela hydraulic and hydrologic model. Development of a FORTRAN version, which included water quality processes, was funded by the Athens, GA, Research Lab of the U.S. Environmental Protection Agency and released in 1974 under its current name Hydrologic Simulation Program, Fortran (HSPF). In the 1980s, pre- and post-processing software, algorithm enhancements, and use of the USGS binary Watershed Data Management (WDM) system were developed jointly by the U.S. Geological Survey (USGS) and EPA. This included work performed by HydroComp, Inc. and included the development of the original user's manual as part of the Version 5.0 release. Since 1980, all model code changes have been maintained by AQUA TERRA Consultants (now a subsidiary of RESPEC), under contract with EPA and USGS. During the mid to late 1990s, Tetra Tech, Inc., under contract with EPA developed the BASINS system and Non-point Source Model (NPSM), resulting in the first Windows-based interface for the HSPF model. The current supported model release is Version 12.2, distributed with BASINS 4.1 as the WinHSPF model interface. WinHSPF is a standalone application, however, and can be run outside of the BASINS platform. The version 12 series includes a number of new options and enhancements, as well as bug fixes. AQUA TERRA Consultants also offer Version 12.4 (containing increased array bounds and minor bug fixes) as a standalone download, although it is still a beta version under internal peer review. HSPF Version 12.4 or 12.5 is anticipated to be included in the forthcoming release of BASINS 4.5. MODEL STATUS HSPF Version 12.2 is distributed with BASINS 4.1, with an initial release in 2013. WinHSPF Version 3.0 beta and Version 2.3 are distributed with BASINS 4.1 as GUI's for the underlying HSPF algorithms and can be downloaded at https://www.epa.gov/exposure-assessment-models/basins-download-and-installation. The HSPF algorithms are coded in FORTRAN 77. HSPF Version 11.0, released in 1996 is available from USGS at https://water.usgs.gov/software/HSPF/ All versions of HSPF are nonproprietary.

Like HSPF, LSPC is a comprehensive model for the simulation of watershed hydrology and water quality for both conventional pollutants and toxic chemicals. It enables simulation of both land based runoff, temperature, and pollutant loading with instream hydraulic and pollutant fate and transport processes in 1-dimensional stream channels. Watershed hydrology simulations are based on the Stanford Watershed Model and consist of a water balance method that defines the water storage for surface and soil layers. Water storage is modified by interception, infiltration, evapotranspiration, and losses to inactive groundwater with outflows simulated from surface and subsurface (interflow and groundwater outflow) layers. Sediment is simulated as cohesive (silt and clay) and non-cohesive (sand) fractions with loading based on detachment/scour and transport algorithms. Other pollutant loads can be simulated generally using build-up washoff functions and instream transport and fate processes or using the eutrophication modules that explicitly represent the transformation, interaction, and fate of nutrients, phytoplankton, and gases. LSPC is the Loading Simulation Program in C++, a watershed modeling system that includes a streamlined subset of Hydrologic Simulation Program FORTRAN (HSPF) Version 11.0 algorithms for simulating hydrology, sediment, and general water quality on land as well as a detailed stream transport model. There is no inherent limit on the size of the watershed that can be represented in LSPC and it simulates land and instream processes simultaneously. MODEL DEVELOPER/STEWARD LSPC was developed by Tetra Tech, Inc. with funding from the U.S. Environmental Protection Agency (EPA). The initial public release (Version 1.0) was made available in 2002.

Based on QUAL2K (Chapra and Pelletier 2003), it includes additional processes and options relative to QUAL2K. Both models are modernized version of EPAs QUAL2E model, incorporating more recent science and allowing for application to shallow, upland streams. QUAL2E, QUAL2K, and QUAL2Kw have historically been applied to steady state representation of stream responses with diel variability in boundary conditions. Version 6 of QUAL2Kw now allows continuous simulation with non-steady, non-uniform flow using kinematic wave flow routing. The model framework includes a genetic algorithm to automate the calibration of kinetic parameters and provides capabilities for Monte Carlo simulation investigation of uncertainty and sensitivity. Water quality simulations include nutrient dynamics, algal production, dissolved oxygen with the impact of benthic and carbonaceous demand, pH, and alkalinity.

The model co-developer, Greg Pelletier, may offer training on QUAL2Kw. 40 ------- SPARROW The SPAtiallv Referenced Regressions On Watershed attributes (SPARROW) model applies statistical methods to relate measured water quality with local landscape characteristics. The model uses a multi-variable regression equation to relate instream water quality measurements to those characteristics, including land use, point sources, soil type, precipitation, and other environmental measures. The model also explicitly considers factors that affect the timing and delivery of pollutants. This statistical approach to non-conservative transport allows the model to estimate loads in ungaged basins, assuming that the explanatory datasets are available to characterize the area under examination. Empirical estimates of relative source contributions are also included. In general, model output is used to describe water quality loading and concentration conditions representative of long-term averages. MODEL DEVELOPER/STEWARD SPARROW was developed by the United States Geological Survey (USGS). Richard Smith, Gregory Schwarz, and Richard Alexander are the original developers of SPARROW.

SWAT is widely used in assessing soil erosion prevention and control, nonpoint source pollution control and regional management in watersheds, especially agricultural watersheds. SWAT incorporates the EPIC plant growth model. Runoff is generally simulated using a modified Curve Number approach, although Green- Ampt infiltration can also be used, while sediment yield is based on the Modified Universal Soil Loss Equation (MUSLE). Instream simulation uses a daily time step. MODEL DEVELOPER/STEWARD The Soil and Water Assessment Tool (SWAT) is a watershed model jointly developed and maintained by the U.S. Department of Agriculture (USDA) Agricultural Research Service (ARS) and Texas A&M AgriLife Reasearch, which is part of The Texas A&M University System. MODEL STATUS The current model version is SWAT2012 rev. 664, released in December 2016. CODE LANGUAGE The model code language is FORTRAN (including sections in both FORTRAN 77 and FORTRAN 90 styles). SWAT undergoes frequent revisions. The major version history of the SWAT model is provided in Table 13, which includes all versions currently available for download. SWAT99.2 and SWAT98.1 are no longer available for download. For information about these earlier versions, contact Jeff Arnold (jeff.arnold@ars.usda.gov) or Nancy Sammons (nancy.sammons@ars.usda.gov).

Journal of the American Water Resources Association QAWRA). 53(3]:532-546. TRAINING MATERIALS The Grassland, Soil and Water Research Laboratory and Blackland Research Center in Texas cosponsor workshops periodically. The SWAT development team also collaborates with other agencies/firms to set up workshops outside of Texas. The site swat.tamu.edu/workshops/ provides summaries of the different types of workshops provided and a list of upcoming events. In addition to the workshops, there are also training videos available that enable online instruction for SWAT users (see swat.tamu.edu/workshops/instructional-videos/). 47 ------- SWMM The Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for continuous simulation of runoff quantity and quality from primarily urban and suburban watersheds. The runoff component of SWMM operates on a collection of subcatchment areas that receive precipitation and generate runoff and pollutant loads. The routing portion of SWMM transports this runoff through a system of pipes, channels, storage/treatment devices, pumps, and regulators. SWMM tracks the quantity and quality of runoff generated within each subcatchment, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period comprised of multiple time steps. SWMM flow simulations include fully dynamic flow routing that allows for backwater, surcharging, pressurized flow, and looped connections. SWMM is also capable of simulating a variety of Low Impact Development (LID) practices (such as bio-retention cells, permeable pavement, and green roofs) as well as more traditional storage-based BMPs (such as detention ponds). It has been widely applied for more than 40 years for the assessment of urban stormwater systems, including combined storm sewers. SWMM is the engine for EPA's National Stormwater Calculator software. MODEL DEVELOPER/STEWARD SWMM was first released in 1971 with funding from the Water Quality Office of the U.S. Environmental Protection Agency (EPA) with development led by Metcalf & Eddy, Inc., the University of Florida, and Water Resources Engineers, Inc. During the 1980's and 90's the model was periodically updated by the University of Florida, Oregon State University and CDM-Smith with funding and oversight provided by the EPA Research Lab, Athens, GA. In 2002 a CRADA was established between the EPA National Risk Management Research Laboratory (NRMRL) and CDM- Smith to re-write the entire SWMM computational model in object-based C and provide it with a modern graphical user interface. The result of this effort, SWMM 5, was released in 2005. NRMRL has continued to develop SWMM in-house, by adding new features such as LID modeling and making numerous other improvements. The current version of SWMM, release 5.1.012, is maintained by EPA NRMRL. MODEL STATUS The current version of SWMM (5.1.013) was released in 2018. MODEL LANGUAGE The SWMM computational engine is coded in C and exists as both a dynamic link library (DLL) and a stand-alone command line executable. SWMM's graphical user interface is written in Delphi-Pascal for the Windows operating system and is used in conjunction with the engine's DLL to run a simulation. EPA's version of SWMM is non-proprietary, open source, and public domain. In addition to non-proprietary versions of SWMM, there are numerous examples of developers layering custom "wrappers" onto the SWMM algorithms to streamline the model setup for users, as well as provide enhanced functionality, as well as management and visualization tools. Two of the most used of these non-proprietary versions include PCSWMM developed by Computational Hydraulics International (CHI) and XPSWMM developed by XP solutions. Information for these model versions can be accessed from their respective websites at: https://www.pcswmm.com/ http://xpsolutions.com/software/xpswmm/ ACCESSIBILITY 48 ------- EXECUTABLE AND SOURCE CODE The SWMM Model Version 5.1.012 executable and source code is available at https://www.epa.gov/water- research/storm-water-management-model-swmm#downloads.

SWTOOLBOX The Surface Water Toolbox (SWToolbox) combines EPAs DFLOW program and USGS' SWSTAT tool into a single tool designed to facilitate easy import of USGS NWIS streamflow data and user-defined text files. SWToolbox contains a set of procedures for statistical analysis of time-series data to support water-quantity and water-quality modeling. It is primarily geared toward conducting n-day frequency computations (e.g., 7Q-10 flows) as well as computing biologically critical flows. SWToolbox can specifically perform flow-duration analysis; compute an n-day high or low annual time series; perform frequency analysis using the log-Pearson Type III distribution; perform Kendall Tau analysis for trend; and compute duration hydrograph tables and curves. MODEL DEVELOPER/STEWARD The SWToolbox was developed in partnership with U.S. Geological Survey (USGS) and U.S. Environmental Protection Agency (EPA) with technical support provided by RESPEC. MODEL STATUS SWToolbox was publicly released in early 2018. The Watershed Academy is hosting a webcast for the Surface Water Toolbox on February 8th, 2018. 50 ------- ACCESSIBILITY The tool can be downloaded from https://water.usgs.gov/osw/swtoolbox/.

Visual Plumes supersedes the DOS PLUMES (Baumgartner, Frick, and Roberts 1994) mixing zone modeling system. Visual Plumes is used for simulating plumes in all waterbody types. It assists in the preparation of mixing zone analyses for NPDES permits. Visual Plumes simulates single and merging submerged plumes in arbitrarily stratified ambient flow and buoyant surface discharges. Visual Plumes incorporates a suite of models including: DKHW model that is based on UDKHDEN (Muellenhoff et al. 1985), the surface discharge model PDS (Davis 1999), the three-dimensional UM3 model based on UM, and the NRFIELD model based on RSB. These models can be run consecutively and compared graphically to help assess performance and uncertainty. MODEL DEVELOPER/STEWARD Visual Plumes was developed by the U.S. Environmental Protection Agency's (EPA) Center for Exposure Assessment Modeling (CEAM) and is a Windows-based model that replaces DOS PLUMES developed by Baumgartner, Frick and Roberts in 1994. Various entities have contributed in the development of the modeling system, namely the National Exposure Research Laboratory (NERL) of the U.S. EPA in Athens, Georgia; CH2M HILL in Corvallis, Oregon; Brown and Caldwell in Atlanta, Georgia, University of Arizona in Tucson, Arizona and Alaska Department of Environmental Conservation in Juneau, Alaska. MODEL STATUS The application is non-proprietary and is updated periodically; it was updated in August 2018. The latest version (Plumesl8c.exe) is available for download from the State of California Water Resources Control Board (SWRCB) at https://www.waterboards.ca.gov/water issues/programs/ocean/. Original versions (Plumes.exe, 2001; and Plumes60.exe, 2003) remain available from the EPA CEAM's website at https://www.epa.gov/exposure- assessment-models/visual-plumes. However this site does not include recent updates to Visual Plumes; the latest versions can be obtained from the SWRCB site. MODEL CODE The Visual Plumes application coding language is Delphi (a Pascal derivative including the Visual Component Language, or VCL). Visual Plumes runs on Windows versions up to and including Windows 10. Since the release of Visual Plumes version 1.0 in 2001, numerous changes have been made to the application to improve its performance. Major changes to the Visual Plumes modeling system include: Contouring Far-field progressive vector diagram (PVD) plume tracking Plume morphology in small streams beyond the fully-mixed region Arbitrary source location ACCESSIBILITY The U.S. EPA Visual Plumes model can be downloaded and installed from the SWRCB Ocean Division: (https://www.waterboards.ca.gov/water issues/programs/ocean/).

The materials are based on the California State Water Resources Control Board mixing zone course (February 2000, presented by Walter Frick and Debra Denton) and subsequent similar courses. These materials are intended as classroom visual aids; however, they can also be used as training for individual users. 54 ------- WASP The Water Quality Analysis Simulation Program (WASP8) is a dynamic compartment (or segment)-modeling program for aquatic systems, including both the water column and the underlying benthos. WASP can be linked to free surface hydrodynamic models (e.g., EFDC) to allow the user to investigate water quality dynamics in 1, 2, and 3 dimensional systems (streams, rivers, lakes and estuaries). The hydrodynamic models provide WASP information related to flows, depths, velocities, temperature and salinity. The constituents that can be modeled by WASP include conventional water quality variables (nitrogen, phosphorus, dissolved oxygen, biological oxygen demand, sediment oxygen demand, algae and periphyton), organic chemicals, metals, mercury, pathogens and temperature. WASP can also be linked with watershed models, which allows for multi-year analysis under varying meteorological and environmental conditions. MODEL DEVELOPER/STEWARD The WASP model was first developed in 1981 by Dominic Di Toro, James Fitzpatrick and Robert Thomann of Hydroscience, Inc., now HydroQual, Inc. Current funding and maintenance of the WASP model is provided by the U.S. Environmental Protection Agency's (EPA) Center for Exposure Assessment Modeling (CEAM). Tim Wool at EPA Region 4 maintains the latest version of WASP (timffitwool.com). MODEL STATUS The current model version is WASP 8.1, released in July 2017. The model code language is FORTRAN and the model interface is in C++. Previous versions of WASP include WASP7.52, 6, 5.1, 5 and 4. WASP6 was the first version with a windows interface; however, the source code is no longer available. The WASP versions still available for download are presented in Table 15. Table 15.
