ABSTRACT
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS 4.1) is a
program developed by the US EPA for local, regional, and state agencies responsible for water
resources management, particularly the development of total maximum daily loads (TMDLs) as
required under the Clean Water Act (CWA). BASINS facilitates water quantity and quality
modeling applications to support EPA's policy and regulatory decisions, e.g., water quality
criteria development and total maximum daily load calculations. BASINS 4.1 has pre-packaged
cartographic, environmental, and climate data within its databases and BASINS users in the
United States often use it. Where pre-packaged data is not available, however, BASINS users
must obtain data from other sources and upload it to BASINS. This tutorial summarizes data
requirements of BASINS users who want to use data other than pre-packaged or who want to
apply BASINS/HSPF to watersheds outside the United States. This report presents steps to
import data to BASINS, delineate watersheds, and launch BASINS to build an HSPF model
project.

PART I. BASINS & HSPF USER INFORMATION
APPLICATION OF BASINS/HSPF TO DATA-SCARCE WATERSHEDS
-------
Chapter 1: Introduction
As local, regional, national, and international agencies and organizations tackle water quality and
quantity issues with watershed-based solutions, it is necessary to model watershed characteristics
and responses to rainfall and pollution effectively. BASINS (Better Assessment Science
Integrating Point and Nonpoint Sources) is a multi-purpose tool that enables users to delineate
watersheds, perform various analyses, and manage data. HSPF (Hydrological Simulation
Program—Fortran) is the core watershed model in BASINS. BASINS also has other models
including SWAT (Soil Water Assessment Tool), SWMM (Stormwater Management Model), and
WASP (Water Quality Analysis Simulation Program).
1.1 Purpose
This document has been written specifically for HSPF users. It facilitates the use of
BASINSVHSPF in watersheds where pre-packaged BASINS data is not available.
1.2 Introduction to BASINS 4.1
BASINS is a watershed assessment tool used for downloading data, delineating watersheds,
building modeling projects, evaluating data, and developing reports. BASINS utilizes a
geographic information system (GIS) framework to analyze geospatial data and other tools that
generate charts or summarize data.
Following enactment of the Clean Water Act Section 303(d), the United States Environmental
Protection Agency (EPA) developed BASINS to establish measures of total maximum daily
loads (TMDLs) for water quality-impaired water bodies and to allow local, state, and regional
agencies to perform watershed analyses. The Office of Water within EPA created BASINS
specifically to address three key objectives:
1. Facilitate examination of environmental information,
2. Support analysis of environmental systems, and
3. Provide a framework for examining management alternatives.
Before BASINS was developed, conventional approaches to watershed analyses and HSPF
model applications were tedious efforts that required many steps and a variety of tools and
computer software. The BASINS environment facilitates data acquisition, data management,
geographic data processing, and watershed delineation. BASINS provides model-specific data
input formatting capabilities and can parameterize and launch models including HSPF, SWMM,
SWAT, and WASP. This intuitive and efficient design not only decreases processing time but
also minimizes errors associated with incompatible data formats for each model. When available,
BASINS allows users to incorporate higher resolution local data in place of the pre-packaged
datasets. International BASINS users whose study areas are outside the United States may obtain
input data from external sources following the guidelines presented in this document.

1.2.1 Additional Features and Compatible Programs
One quality that makes BASINS a multi-purpose tool is its compatibility with other programs,
assessment tools, models, and post-processing tools. The table below describes the utilities available
within BASINS and additional features that can be downloaded separately (Table 1). Readers are
strongly encouraged to view the full list of BASINS-related information on the BASINS website.

1.3 Introduction to HSPF Modeling
HSPF was developed in the early 1960s as the Stanford Watershed Model (SWM). SWM was a
hydrology model until water quality modeling capabilities were added in the 1970s. The
Ecosystem Research Laboratory in Athens, GA funded development of the Fortran version that
combined three programs: the EPA Agricultural Runoff Management Model (ARM), the EPA
Nonpoint Source Runoff Model (NFS), and a privately developed, proprietary Hydrologic
Simulation Program (HSP).
As mentioned above, HSPF simulates water quantity and quality at user-specified spatial and
temporal scales. The model's simulation timestep — from sub-hourly to daily to monthly, with a
duration of a couple minutes to hundreds of years can be specified. HSPF can assess the effects
of land-use change (e.g., urbanization), reservoir operations, point and nonpoint source pollutant
loadings, and flow diversions.
1.3.1 Applications and Model Capabilities
HSPF modeling applications include:
Flood control planning and operations
Hydropower studies
River basin and watershed planning
APPLICATION OF BASINS/HSPF TO DATA-SCARCE WATERSHEDS
-------
• Storm drainage analyses
• Water quality planning and management
• Point and nonpoint source pollution analyses
• Soil erosion and sediment transport studies
• Evaluation of urban and agricultural best management practices (BMPs)
• Fate, transport, exposure assessment, and control of pesticides, nutrients, and toxic
substances
Beyond those general capabilities, individual utilities and application modules perform functions
that serve specific modeling purposes. The three HSPF application modules summarized below
simulate water quality and quantity from three land use segments: IMPLND, PERLND, and
RCFIRES that represent impervious land, pervious land, and stream reaches, respectively.
PERLND
The PERLND land segment simulates water quality and water balance for pervious land
surfaces. PERLND accounts for different flow types (e.g., surface runoff, interflow, and
baseflow), and tracks chemicals transported by these flows.
IMPLND
IMPLND represents impervious urban areas. Due to the nature of this land cover, the primary
mode of pollutant removal is surface runoff.
RCHRES
This module represents water bodies such as streams, rivers and lakes. HSPF simulates flow and
water quality constituents that include biochemical oxygen demand, temperature, hydraulic
behavior, sediment deposition, chemical decay and transport, dissolved oxygen, alkalinity, pH
and carbon dioxide.
1.3.2 HSPF Assumptions and Limitations
As with all modeling programs, HSPF has limitations. It is dependent on the accuracy and
resolution of the input data. Additionally, it requires significant amounts of input data and users
must have strong modeling skills and adequate training. Explore tutorials and user information
on EPA's Website.
1.4 Additional BASINS/HSPF Supporting Software
Depending on user needs, BASINS/HSPF users may require or benefit from freely available
supplemental programs in addition to the BASINS/HSPF software.
APPLICATION OF BASINS/HSPF TO DATA-SCARCE WATERSHEDS
-------
1.4.1GIS Software
3DEM Visualization Software: Depending on the size of a watershed, the user may
need to merge multiple DEM files, but geo-processing tools in BASINS may not be able
to do so. 3DEM, available for download here, is less restrictive in file size when merging
OEMs for use in BASINS. The program also allows DEM editing.
MapWindow: Map Window is a spatial data viewer and GIS tool that the BASINS
graphical user interface (GUI) was built upon which allows users to perform geospatial
analyses and geo-processing tasks such as projection of data layers. Note that
MapWindow is pre-packaged in BASINS, but users may also download it from the
MapWindow website and install it separately.
1.4.2 Time Series Data Management Software
• WDMUtil: WDMUtil enables users to import HSPF model input data into a WDM
(Watershed Data Management) file. This program is available free from the AQUA
TERRA website and EPA has published a tutorial explaining how to use WDMUtil to
properly format input time series data into a WDM. It is necessary to use scripts that can
read the data format, as described in the aforementioned hyperlink and defined in the
User's Manual that can be accessed through WDMUtil at the Help tab. The tutorial
hyperlinked above also explains other capabilities of the WDMUtil.
• HSPF Data Formatting Tool (HDFT): While WDMUtil is useful for coarse resolution
time series data, it has limited capabilities for other formats, including data with sub-
hourly temporal resolutions. HDFT was designed to format such fine resolution data for
use in HSPF. It is available in web-based and desktop-based versions. Information
regarding HDFT's data-formatting capabilities can be found here. Tutorials on how to
use the HDFT versions are included in the HDFT Report.
• SARA Time Series Utility: This data management tool developed by AQUA TERRA
Consultants allows users to import times series data and produce WDM files that can be
added to and used in BASINS. It can be downloaded from the AQUA TERRA Website.

Chapter 2: BASINS/HSPF Data Requirement
The use of BASINS to perform watershed delineation with data not accessible from within
BASINS requires additional data acquisition procedures. The steps illustrated in Figure 1 are
explained in detail in Chapters 3 and 4. This chapter summarizes BASINS/HSPF data
requirements and potential data sources.

2.1 Minimum Required Data and Sources
Before performing watershed analyses and running HSPF using BASINS, acquiring sufficient
input data is necessary. This section discusses the input data required to perform a successful
HSPF simulation, and where users may obtain input if data sources accessible from within
BASINS are inadequate for watershed analysis. Data sources outlined below represent a basic
list; site-specific data may be available from regional agencies and/or downloadable from other
sites on the internet. Minimum data required for BASINS/HSPF include GIS data (e.g. DEM,
land cover, and river networks) and climate data such as precipitation and evapotranspiration.
2.1.1. Digital Elevation Models (OEMs)
Digital elevation models are GIS layers, usually of raster type, whose cell values describe the
elevations of an area. They are generated through processes involving remote sensing technology
and are required for BASINS to perform watershed delineations. Geospatial data layers like
OEMs can be projected in a number of different coordinate systems; as such, it is necessary to
know their projection and reference datum to ensure that all other geographic data is projected
accordingly. BASINS requires OEMs to be in a projected coordinate system as explained in
Chapter 3.
• Global Data Explorer: This interactive mapping interface enables registered users to
download OEMs and other geographic data; users can register by following the steps
outlined on the website which are also included in Appendix A. The Global Data
Explorer is the result of collaboration between Land Processes Distributed Active
Archive Center (LP DAAC), a joint NASA and USGS data center, and George Mason
University's Center for Spatial Information Science and Systems. A number of geospatial
datasets are available for download from this resource, including ASTR Global DEM,
NASA Blue Marble, and NASA and NGA STRM.
Website: http://gdex.cr.usgs.gov/gdex/
2.1.2. Land Use Data
Incorporating land use data enables BASINS to estimate land use categories in a watershed. To
minimize HSPF model output errors, the resolution of the land cover data should be as high as
possible, particularly for small watersheds. When land use and land cover data are not available
within the BASINS software package, users can download data from the following global
databases:
• Global Land Cover 2000: The European Commission's Joint Research Centre (JRC)
organized a global collaboration for sharing land use data. The website provides relevant
metadata. Descriptions of the project include the source of the data, projection, and other
information that help BASINS users assess its accuracy and applicability. An example
data extraction is included in Appendix C.
Website: http://bioval.irc.ec.europa.eu/products/glc2000/products.php
APPLICATION OF BASINS/HSPF TO DATA-SCARCE WATERSHEDS
-------
• USGS Land Cover Institute: This site contains links to various land cover data sources
including land use trends, soil characteristics, and forest fire maps. Some sources cannot
be incorporated into an HSPF modeling project, however, they may be of interest to
BASINS users as the data can assist in judging if further sub-delineation/segmentation is
needed, based on land surface characteristics.
Website: http://landcover.usgs.gov/landcoverdata.php
2.1.3 Climate Data
Since BASINS was developed for use in the United States, default units are in U.S. customary
units. International users must convert input from International System of Units (SI) to US
customary units while running the HSPF Model see Table 3 for conversion factors. Chapter 4:
HSPF Application Example shows how to perform a conversion. Table 3 contains key input
parameters, default BASINS/HSPF U.S. customary units, and the conversion factors required to
convert data from SI to US customary units.

HSPF requires different input data for different modeling applications. Table 4 summarizes the
data needs for the three different application modules, PERLND, EVIPLND, and RCHRES. For
more information on modeling options and applications, review tutorials on the EPA BASINS
webpage. HSPF Input data must be imported into a Weather Data Management (WDM) format
in time steps congruent with those required by the intended application. In general, data of
hourly time steps is required, but not always available. The WDMUtil software can be used to
disaggregate daily data to hourly data. WDMUtil can also calculate potential evapotranspiration
from meteorological data. Note that sub-hourly simulation time steps are more appropriate for
event-based urban stormwater modeling applications and hourly simulation time steps are
typically used for continuous simulation of non-urban watersheds. A link to the WDMUtil
download site is included in Section 1.4.2.
Table 4 illustrates the meteorological data required by the HSPF model for water quantity and
quality modeling applications. Note: for water quantity (streamflow) simulation, only
precipitation and evapotranspiration are required.

2.2 Other Useful Data and Sources
To increase reliability of model-generated output, BASINS users are encouraged to find the best
available input data. Depending on intended use of the HSPF model, input data requirements will
vary. The sections below provide information on additional publicly available data sources.
2.2.1 Soil
Soil data may be necessary to perform simulations on erosion and sediment transport.
International BASINS users can use the digital soil map of the world.
• Digital Soil Map of the World: The Food and Agricultural Organization of the United
Nations' GeoNetwork has maps and publicly available data for download such as the
Digital Soil Map of the World. A tutorial demonstrating how to download this map is
included in Appendix D.
Website: http://www.fao.org/geonetwork/srv/en/metadata. show?id= 14116
2.2.2 Hydrogeographic Data
Hydrogeographic data including stream networks are generally polyline shape files that
designate locations of streams. They are often developed the same way BASINS develops stream
segments - by geo-processing digital elevation data. These files can improve the accuracy of
watershed delineation and watershed analysis, particularly when the stream file has higher
resolution than the DEM. Stream files can often be useful when using OEMs of very high
resolution, as such datasets may contain large amounts of noise that make it difficult for BASINS
or other GIS software to accurately identify the stream network.
• USGS HydroSHEDS: The USGS-developed stream and river network files from 90 m
resolution OEMs obtained from NASA's Shuttle Radar Topography Mission (SRTM).
This source also contains other geo-referenced data sets. A tutorial demonstrating how to
download data layers is included in Appendix B.
Website: http://hydrosheds.cr.usgs.gov/dataavail.php
2.2.3 Global Flow Data
Calibrating HSPF model simulated streamflow is vital for refining the model's parameter values
and providing more accurate simulations. Flow data from specific outlet points is required to
perform such calibrations. When delineating watersheds, it is recommended to select an outlet
point corresponding to the location of a stream gauge that measures river flow. Like climate data,
these must be formatted in a time-series and added to the WDM file.
• Global Runoff Data Centre (GRDC): This organization works under the auspices of the
World Meteorological Organization, in partnership with the German Federal Institute of
Hydrology. The site contains global flow data and associated metadata which can be

Chapter 3: BASINS Application Example
This chapter presents the steps required to build an HSPF Model project within BASINS for a
tributary of the Shebelle Watershed in central Ethiopia (Figure 2). The approximate area is 2400
square kilometers, or 927 square miles. The files used in this tutorial are available for download
at the following web address and information about the files are included in this document's
appendices: http://www2.epa.gov/exposure-assessment-models/tmdl-models-and-tools
Figure 2: Location of Upper Shebelle Tributary in Ethiopia
3.1 Starting a new BASINS project
When using BASINS within boundaries of the United States, required input data can be acquired
from sources accessible within the software package. BASINS users in other countries, however,
must obtain BASINS/HSPF data elsewhere. This tutorial guides users through that process.
a. Download BASINS from the EPA Website and install the program. Depending on the
intended application, install additional programs discussed in Section 1.2.1.
b. Open BASINS 4.1. Figure 3 shows the welcome screen.

a. Add the DEM to BASINS. After downloading the DEM(s), click the Add Layer Icon L^J in
Basins, navigate to the file and Open it. Users can adjust the projection, merge rasters, and
perform other geo-processing activities with available tools.
b. Check the projection. Since the DEM was downloaded in the same coordinate system as the
map project, no projection is required. BASINS may not be able to identify the projection of the
DEM when imported to the project, however, and if that is the case, the following pop-up
window (Figure 7) will appear. Since we know the DEM used for this example is the same as
the map project, click 'Assign projection from project'. If you also know remaining data layers
will be in the same projection, check the box beside 'Use this answer for the rest files'.

3.3 Adding River Network Files
The river network file for the watershed was downloaded from the USGS HydroSHEDS
Database. The default coordinate system is a geographic system (latitude/longitude) referenced
to WGS84 datum, and is the same as the DEM downloaded in this example.
a. Following the same procedure for adding the DEM to the BASINS Project, add the river file.

3.4 Adding Land Cover Data
Note: The terms "Land Use" and "Land Cover" are used interchangeably throughout this
document.
a. Land cover data can be added as a raster file or a shapefile. The land cover data in this tutorial
was a raster downloaded from the Global Land Cover 2000 (GLC) (see Appendix C). Specific
characteristics of the land use files vary slightly between different regions in the GLC. It is
therefore essential to get more information about the land use data prior to incorporating these
files into an analysis. The land use dataset for Africa, like many other continents, has a 1-km
resolution. The default coordinate system for the downloaded dataset for this example is the
WGS84 geographic (Lat/Long) coordinate system (the same coordinate system as the
downloaded DEM and streamline shapefile).
b. Once the land use raster is added to the BASINS project and the layers are adjusted so it is in the
background, the map window should resemble Figure 12.

3.5 Clipping input data in BASINS
The smallest river network and land cover dataset that can be downloaded for the region in this
example is the entire continent of Africa. To minimize the amount of data BASINS must store
and process, the layers can be clipped to a smaller, more manageable size. There are several
ways to do this, but one is to create a polygon shapefile around the watershed area, then clip the
dataset to it. This method is described below. In the event this causes BASINS to crash, skip to
Step o. for an alternative clipping method.
a. A Clipping Box shapefile has been provided with the tutorial, or you can create a new one by
The New Shape File Options Dialog box will appear
clicking the New Shapefile icon
(Figure 13).

b. Click the '...' button to save the shape file in a location other than the default. Users may need
to type the name of shapefile in the directory listing to save it.
c. Select 'Polygon' as the shapefile type and press 'OK'.
d. The following window (Figure 14) will appear; press 'OK' to dismiss the warning and
continue.
Importantlnformation!
An empty shapefile has been created. Before adding shapes, make sure
that your extents are set properly. To make sure extents are correct load
an image, grid or shapefile that is located in the same area.
Figure 14: Checking Extents Set-Up
e. Create a polygon feature around the watershed area by clicking the Add Shape icon L^ll while
the Clipping Box layer is selected on the Data Layers Table of Contents, although this may not
be necessary since that shapefile has already been selected if you are following the tutorial.
Create vertices around the DEM where you will clip the river network and land cover raster by
clicking points on the map window around the DEM (see Figure 15). It may be necessary to
zoom out prior to creating vertices.
f. To complete the polygon feature, double-click on the origin of the polygon or right click. The
finished box is shown in Figure 16. Note that the Clipping Box is the active layer since the name
is highlighted in the Data Layers Table of Contents. To bring the DEM layer back to the top,
click on the Clipping Box layer in the legend and drag it below the DEM and River layers. The
result of the reorganized data layers is shown in Figure 17.

3.6. Reprojection of files to UTM 37N
a. For BASINS to properly read and use input files for watershed delineation, files must have a
projected coordinate system. As such, each of the three input files (River file, DEM, and land
cover raster) must be re-projected from their current WGS84 geographic projection. In this
example, each file was re-projected to UTM Zone 37N.
b. If the input files do not have a projection assigned, the re-projection tool will not process
correctly Use the "Assign Projection to Shapefile" or "Assign Projection to Grids" tools, and
select the geographical WGS 84 projection to assign to the files.
c. The "Reproject Shapefile" tool in the Projections folder of the toolbox is used to re-project
the Clipped River File to UTM Zone 37N. This projection can be found by referring to the
hierarchical organization of projections shown in Figure 27.

grid. When both have been specified, click OK, select UTM Zone 37N from the list of
projections, and click OK.
e. After re-projecting the input files to UTM 37N, it is suggested that users close the current
project and open a new BASINS project. For the new project, select UTM 37N as the data frame
projection prior to importing the newly re-projected stream, land cover, and DEM files and
proceeding to watershed delineation.
3.7 Watershed Delineation
Now that input files have been clipped and properly projected, users may initiate watershed
delineation. This tutorial shows how to use automatic delineation. BASINS is also equipped with
a manual delineation option which is recommended if the user is very familiar with the
topography of the watershed.
a. Click on Watershed Delineation in the toolbar at the top of the window, then 'Automatic',
as illustrated in Figure 28.

• If an outlet point shapefile has already been added to the project, select it by clicking the
drop-down menu in the Custom Inlet/Outlet Definition and Delineation Completion
and select the outlet shapefile. For this tutorial, use the Outlet Point shapefile provided.
• If users wish to have specific outlets or points for the watershed and have not yet added
them to the BASINS project, click 'Draw Inlets/Outlets' to create a new shapefile. Click
'Yes' in the Create new Outlets/Inlets File dialog box (Figure 30), specify the working
directory in which the created shapefile should be saved, and provide a shapefile name.

The Network Delineation by Threshold Method section allows the user to define
the number of sub-basins BASINS delineates. The number and size of sub-basins
appropriate for a particular project depend on several factors. Generally, as the
number of sub-basins increases, the level of spatial detail for the generated watershed
will also increase. To increase the number of sub-basins, decrease the threshold. If a
watershed is very large and without significant variability in land cover, soil
characteristics or weather patterns, fewer sub-basins will typically be needed to
develop and run an efficient modeling project.
h. After the dialog box is completed as depicted in Figure 29, press 'Run All'. Be patient while
BASINS delineates the watershed as processing could take 30-45 minutes or longer. If the
delineation is successful, the map window will resemble Figure 32.

3.7.1 Watershed Delineation Errors
When delineating a watershed, BASINS may encounter memory limit issues. If so, close all
unnecessary programs running on your computer, then close and restart BASINS. Try the
delineation again with the same settings. If the problem continues, the watershed area may be too
large. Delineate a smaller sub-basin by moving the outlet point upstream or clipping the DEM to
a smaller size. Clipping raster files is explained in Section 3.5 A smaller area can also be
analyzed by zooming to the region of interest and checking the box beside 'Use a Focusing
Mask' in the Automatic Watershed Delineation Dialog box. This allows users to manually
specify the analysis extent or use the current window/map view as the extent.
3.8 Land Use Clip
a. In this example, the land cover has already been clipped and re-projected to UTM Zone 37N.
By clicking and dragging names of the data layers in the legend, their order was rearranged so
that the Outlet Merged Watershed generated by the Automatic Delineation was on top,
followed by Africa Land C (Figure 33). Since we are only concerned with land use inside the
watershed, clip the land use raster to the watershed boundary once again.

3.9 Reclassifying Land Use
Since the land surface data was added to the project from a source not accessible within
BASINS, it is necessary to reclassify the raster categories.
a. Find the legend that accompanies the land use metadata which may be included in the
downloaded folder (as here) or elsewhere. To add it directly to BASINS, it must be a database
file; if not available as a database file, the information must be entered manually. Both methods
are explained in the following steps.
b. Click on 'Analysis' in the toolbar and click 'Reclassify Land Use' at the bottom of the menu
(Figure 35). If the 'Analysis' menu is not visible, click 'Plug-ins,' then 'Edit Plug-ins'. Select
'Analysis,' then 'Reclassify Land Use,' and click on the selection box to turn on the plug-in.

c. Select 'User Grid' from the Land Use Type drop-down menu if using a land use raster, or
'Other Shapefile' if using a land use shapefile. As this example uses the raster downloaded from
Global Land Cover 2000, 'User Grid' was selected.
d. Select the clipped land use layer in the Land Use Layer drop-down that is available after
designating Land Use Type. Whether the land use layer has been clipped to the size of the
watershed or not, choose Summarize within Layer by selecting the Outlet Merged Watershed
layer from the drop-down menu. This tells BASINS to calculate percentage of each land use type
in the watershed.

3.10 Adding Soil Data
The Soil Data in this example was downloaded from the UN FAQ Website discussed in Section
2.2.1. The FAO GeoNetwork has a number of options. In this example, the Digital Soil Map of
the World - ESRI shapefile format was chosen (see Appendix D) and projected (from Lat/Long
coordinate system) to align with other data layers.
a. To add the soil map to the BASINS project and trim it to the size of the watershed, follow the
steps to add and clip the previous shapefile data layers. Figure 39 shows the watershed with sub-
basins (thick red outline), land use (colored grid) and soil zones (navy lines).

By comparing soil designations, land use, and watershed segments, users can determine whether
to segment the watershed further to better characterize its properties. Segmentation involves
generating sub-basins with similar land use, soil properties or other land surface characteristics.
The EPA has a lecture on watershed segmentation and a tutorial detailing the watershed
segmentation procedure.

3.11 Adding Climate Data
Climate data must be in U.S. customary units as discussed in Table 3, in Section 2.1.3, and in
WDM file format discussions. EPA's tutorial shows how to use the free WDMUtil software to
import time series data into WDM files. The following flow diagram (Figure 40) summarizes the
process of acquiring local climate data and ensuring that its format is compatible with
BASINS/HSPF. How to find data when local data is not available is outlined in Appendix E.
Refer to Table 4 to determine
weather data requirements for
intended use of HSPF.

Chapter 4: HSPF Application Example
As described in the Introduction, HSPF is a powerful watershed tool that can predict a
watershed's hydrologic response to rain events and simulate water quality. Since the process of
setting up HSPF within BASINS has already been completed, running the model should result in
few problems for international users, but if present, will be limited to unit output and conversion
primarily. This portion of the tutorial introduces basic functions within HSPF and addresses
problems international users may encounter. For a more comprehensive summary of HSPF, refer
to the user manual that can be accessed in the WinHSPF environment by clicking 'Help' on the
tool bar and selecting 'HSPF Manual'., Exercise 4 from the Basins User information and
guidance website also contains a detailed tutorial on running HSPF.
As mentioned previously, it is recommended that users input data in U.S. customary units and
convert output back to desired units which is shown in the following tutorial.
4.1 Starting HSPF
Launching HSPF through BASINS was discussed in Section 3.12. If you have already generated
the model (.uci file) through BASINS, proceed as follows to open the program.
a. Open WinHSPF 3.0. The welcome screen will resemble Figure 51.

Chapter 5: Available Tutorials and Resources
5.1 Tutorials and Training
EPA's BASINS User Information and Guidance
This site contains a library of tutorials and lectures teaching program basics, as well as how to
adjust and calibrate different parameters; among them is a guide to WDMUtil. BASINS-related
publications and additional resources are included in User Information and Guidance. The User
Manual can be found on this page and is also accessible in the BASINS interface by clicking
'Help' on the tool bar and selecting BASINS Documentation.
Introduction to HSPF Modeling
This tutorial appears in the BASINS User Information and Guidance collection. It details how to
use basic editing tools, explains assumptions, and describes default parameter values, that a
BASINS user may be interested in, to calibrate a model.
Hydrological Simulation Program - Fortran (HSPF) Data Formatting Tool (HDFT)
This tool details how to use both the web and desktop versions of HDFT that enable BASINS
and HSPF users to properly format time series data for HSPF using the WDMUtil.
5.2 Documentation and Additional Information
HSPF Support
This site contains HSPF support with a summary of the program. It lists possible applications,
modeling capabilities and limitations, as well as a link to download WinHSPF, WDMUtil, and
other modeling programs and components.
Summary of HSPF
This USGS report summarizes the history of software development, model data requirements,
output options, system requirements, applications, and documentation. It offers resources such
as publications and training.
Note: Some tutorials are written for older versions of a program or utility, but may still be
useful for understanding and running the software. Always check software updates to
determine if changes made in updates affect intended uses and functions.

1. Access the data by clicking on the first link in the email, as shown in Figure 86. The link
connects to a page with data that resembles Figure 87. The format is currently incompatible with
BASINS and must be converted to a WDM file. Due to gaps in the downloaded data, this
example could not be converted easily to a WDM for this region. If this occurs for the selected
study area, an alternative source of time series data must be acquired—possibly from local or
regional agencies and/or universities (refer to Flow Chart in Figure 40).
To learn how to format time series data into a WDM file, visit the WDM Exercise in the
BASINS User Information and Guidance.

Appendix F: Guide to Files to Follow Tutorial
This section contains a guide to files available for download and use with the tutorial. More
information about downloading this data is found in the appendices. All files are ready to be
added directly to BASINS, and can be done so by following the methods described in the
Tutorial.
DEM Folder
This file contains the digital elevation model (DEM) used in the tutorial, as downloaded from the
GDEx.
River File Folder
This folder contains the river shapefile added to BASINS that was downloaded from the USGS
HydroSHEDS.
Outlet Point File Folder
Users can create an outlet point or use the included outlet point. Using the latter produces the
same watershed area as the tutorial.
Land Use File Folder
The land use file was downloaded from the Global Land Cover 2000. In addition to the land
cover raster, this folder contains the legend database file.
Clipping Box Folder
The polygon used to clip the input files to a smaller size more representative of the study area is
stored in this folder.
Soil Map Folder
This file was downloaded from the FAO GeoNetwork. The map is not required for the
delineation or to run HSPF, but demonstrates other applications of the BASINS modeling
environment.
Weather Data Folder
The included WDM was downloaded from a watershed in the United States since weather data
from the Shebelle watershed tributary was not easily obtained. This approach is discouraged,
however.
