The runoff volume is listed for each event, for each source area. The model also calculates the land use runoff coefficient (Rv), the total losses, and the SCS Curve Number for each event. Runoff Volume TabSource Areas
The runoff statistics are summarized for each source area below the event-by-event list.
The model also summarizes the output for the total area, before and after the drainage system, and at the outfall.
With an Outfall Detention Pond - • Peak Reduction Factor • Pond Flushing Ratio • Outlet structure failure • Additional Output – • Runoff coefficient (Rv) • Total losses • SCS Curve Number Runoff Volume TabOutfall
Percentage contribution of runoff volume from each source area, for each land use. Runoff Volume Source Area Percent Contribution Summary
