Model My Watershed Site Storm Model Guide

The Model My Watershed Site Storm Model simulates storm runoff and water quality by applying the TR-55 and STEP-L water-quality models for a single 24-hour rainstorm over a selected land area within the continental United States.

1. Introduction

An overview of the Model My Watershed Site Storm Model and Runoff Simulation.

2. Sign In and Share Location

Get hints for creating an account, logging into an existing account, recovering your username, and resetting your password.

3. Navigate the Map

Navigate the map by clicking and dragging or by searching for a location by name and address.

4. Find Your Watershed

If you chose not to share your location, find the location you want watershed information for by typing an address or city or zip code into the search bar.

5. Choose Basemaps and Overlays

Just as Google Maps allows you to switch between road and satellite maps, there are several options for both the basemap and data overlays on top of the map.

6. Select an Area to Model

You can select your area of interest by choosing a predefined boundary, drawing an area, delineating a watershed, or uploading a polygon.

7. Analyze an Area

The Analyze pane will show stream network statistics, land cover distribution, hydrologic soil group distribution, terrain statistics, and more.

8. Monitor an Area

Start by typing search terms, e.g. “turbidity”, “water” & “MODIS,” to find some datasets that would be useful for your research.

9. Model an Area

There are two models available to simulate stormwater runoff and water quality, to create different conservation and development scenarios, and to compare human impacts of these scenarios.

10. Save and Share a Project

You can name and save your work, make the project publicly accessible, add tags so it can easily be found, print out the maps and graphs, or embed the work into the ITSI portal.
