WMS:Rational Method Edit Parameters

Like the other models supported by WMS, the Rational Method can be defined for a watershed/catchment developed from feature objects, DEMs, or TINs, or built using the tools provided in the hydrologic modeling module under the Tree menu. Once the topologic tree has been constructed the Rational Method dialog can be accessed using the Run Simulation command from the Rational menu.

The Rational Method dialog allows you to enter all of the necessary values for computing a peak flow for a selected catchment area, or confluence point. The values for $C$, $i$, and $A$ represent the values of the currently selected basin or outlet.
