Example1 ======== This example models runoff quantity and quality in a small hypothetical drainage area. It consists of 8 subcatchments connected to a system of 1 to 2 foot diameter storm drains. There are two pollutants (TSS and lead) and two land uses (residential and undeveloped). Rainfall data for both a short-term 36-hour period and a long-term 2 year period are provided. Here are some suggestions for running this example: 1. The model is set up to run in single event mode for a period of 36 hours using Kinematic Wave routing. Run the simulation. 2. View the Status Report for the run, noting the Continuity error. 3. Select some different output variables (e.g. subcatchment runoff, node flooding, link flow) for viewing on the study area map. Use the Day/Time controls on the Map Browser to move back and forth through time. 4. Try animating the map by using the Animator Toolbar (make the toolbar visible by selecting View | Toolbars | Animator from the Main Menu). 5. Try generating some other types of reports, such as a time series plot and a profile plot. 6. Change the Simulation Options to use Dynamic Wave routing and re-run the analysis. 7. Modify the model to run a continuous simulation as follows: a. Edit the rain gage and change its Data Source to File, click on the File Name field and specify the rain data file named sta310301.dat, and enter 310301 for the Station Number. b. Edit the Simulation Options as follows: i. change the Routing Method back to Kinematic Wave ii. make the End Date 01-02-2000 (for a 2-year simulation) iii. change the Routing Time Step to 5 minutes. 8. Run the simulation (it may take several minutes). Try generating a Statistics Report to see how the magnitude of various kinds of events (rainfall, runoff, quality, etc.) are distributed over time.
