Abstract:

SCS Technical Release 20, 'Computer Program for Project Formulation - Hydrology' (TR-20), has been revised. Major revisions include new procedures for hydrograph generation and reach routing, the capacity to develop discharge data for intermediate peaks and for specific flow durations. Only minor changes have been made to the current input formats. A separate new comprehensive data checking program has also been developed.
