Once you have entered all the land use data for your NasHyd commands, save your model and run the simulation. Select Run from the Simulation toolbar and you will see the following window. Under the dropdown menu for water quality select “New WaterQuality” for each design storm. Then click Run to run the model.
Your model results can be displayed as labels, making it easy to see the flow of TP and TSS through the schematic. Note that the water quality at the AddHyd commands is a area weighted average of the water quality values in the upstream commands. The Route Channel and Compound Channel commands do not impact water quality results.
You can compare your results with “Pre-Dev. Solved”. Open the scenario “Pre-Dev. Solved” and run the model by clicking the Run button in the Simulation toolbar. The results will display in labels.
