|---|---|
| Confirm total watershed area is correct | Output Summary → Total Area Modeled (ac) |
| Confirm area modeled in each land use is correct | Review land use summary table shown in the main model space window |
| Confirm source areas or applied SLUs are correct for each land use | Review source area modeling assumptions for each land use |
| Confirm correct number of control devices modeled in drainage network and source areas | Review control practice summary table shown in the main model space window |
| Confirm correct parameters modeled in control practices | Review parameters applied in control practice parameter window for all modeled drainage area and source area control practices |
| Confirm land use, junction, and device routing | Review routing in main model space window |
| Confirm precipitation event totals are correct | Review precipitation dates and rainfall depth totals. Can be accessed through a number of output tabs including "Junction → Runoff Volume" |
| Compare source area outflow pollutant concentration to tabled values | Output: Land Uses → Pollutants → Concentration (mg/L) |
| Compare TSS/TP removal rate to typical tabled values: TSS; TP | Calculate pollutant removal (%) as described here. Note: must have junction elements upstream and downstream of all control practices |
