TR-20 - hydrologic software to model the rainfall-runoff process
WMS includes a comprehensive interface to the TR-20 hydrologic program used by many hydrologic engineers to model the rainfall-runoff process. The
interface has been created in such a way that models can be built from TINs used to delineate basin boundaries and compute geometric data or by manually constructing a series of outlets and basins to form a
topologic representation of the watershed. When a TIN is used, the topologic model is automatically constructed as outlets are added and basins defined. Also, any geometric parameters computed by WMS are supplied to
corresponding TR-20 input fields. .
