Summary
This tutorial reviews some of the screens, icons, and basic functions of the SDMProjectBuilder (SDMPB)
that allow a user to identify an 8-digit HUC (HUC-8) of interest from which a pour point or 12-digit HUC
(HUC-12) can be chosen for a microbial assessment. It demonstrates how to identify and delineate a
HUC8-8, initiate the execution of SDMPB, navigate the SDMPB, use basic functions of the SDMPB tool
bar, and identify and label a HUC-8.
-------
Navigate the SDMPB and Identify a Watershed of Interest
PURPOSE
Automate data acquisition to meet input data requirements for a confederation of models
OBJECTIVE
Identify an 8-digit Hydrologic Unit Code (HUC-8) of interest from which a pour point or 12-digit HUC
(HUC-12) can be chosen for a microbial assessment.
DEMONSTRATION
This tutorial reviews some of the screens, icons, and basic functions of the SDMProjectBuilder (SDMPB)
that allow a user to identify an 8-digit HUC of interest from which a pour point or 12-digit HUC can be
chosen for a microbial assessment. It demonstrates how to
• Identify and delineate an 8-digit HUC
• Initiate the execution of SDMPB
• Navigate the SDMPB
• Use basic functions of the SDMPB tool bar
• Identify a 12-digit HUC
SOFTWARE ACCESS, RETRIEVAL, AND DOWNLOAD
If users have already downloaded and installed the SDMPB to their computers by following the most
current instructions, skip this step; otherwise, follow the installation instructions outlined for the
SDMProjectBuilder in the QMRA tutorial, titled "Installation of Software for Watershed Modeling in
Support of QMRA" (Whelan et al., 2015).
-------
NAVIGATING THE SDMPB AND IDENTIFYING AN 8-DIGIT HUC OF INTEREST
1. An SDMProjectBuilder (SDMPB) shortcut icon should now appear on the computer screen:
Double-click left on the icon to execute the SDMPB application. If you cannot find the icon, locate the
executable on your hard drive (i.e., SDMProjectBuilder.exe), typically at \SDMProjectBuilder\bin.
Execute the program by double-clicking left on the executable.

called the Hydrologic Unit Code (HUC) Catalog Unit (CU). Assign CU numbers to the HUC-8s:

12. We are interested in the Manitowoc River Basin in the County of Manitowoc, Wl (see blue box in
figure below), but there are many ways to identify this watershed. For example, we can zoom to the
general area using the "Zoom In" button 11 on the tool bar. Click it, then go to the "Map" screen
and identify the area to zoom in on, as with the blue box in the figure below.

17. With the "Navigation Helper", zoom to State, County, or HUC-8. If you do not know the HUC 8
identification number, but you know the location, you can type in the "State" and "County" and
choose "Zoom". In our example, we are interested in the watershed in Manitowoc County,
Wisconsin.

18. A user can find a HUC-8 within the United States., by zooming in based on the State and County, or
by directly inputting the HUC-8 identifying Catalog Unit (CU) code. From the figure, we can see that
the HUC-8 CU identification number is 04030101, which we will need to collect data on the HUC-8.
Type or choose "04030101" for "HUC 8", check the "NHD+" and "HUC-12" boxes, then click "Get

by 'HUC-12 for 04030101', deselecting all map layers except the 'hue 12 for 04030101' and
'huc250d3'.

Opaqueness can be changed by sliding the bar labeled 'Opacity.' Check results by choosing 'Apply.' Now,
pick 'OK.' 'Line Width' and 'Outline Color' can also be modified; modifying the 'Line Width' is very
helpful in differentiating boundaries, stream networks, etc.
32. In this example, we are interested in the Manitowoc Watershed which is a subset of the HUC-8. The
