TR-20: Project Formulation - Hydrology. Author: USDA Soil Conservation Service (SCS) Now Natural Resources Conservation Service (NRCS) "The TR-20 program provides a hydrologic analyses of a watershed under present conditions.... Output consists of peaks and/or flood hydrographs....
TR-20 is a computer program for the simulation of runoff occurring from a single storm event. The program develops flood hydrographs from runoff and routes the flow through stream channels and reservoirs.
If you are using SCS Unit hydrograph method with SCS loss method, the results should match closely with TR-20 hydrology. TR-20 represents the full-bore implementation of these methods, whereas TR-55 is a more simplified version that lent itself more to hand calculations.
Technical engineering manuals and installation manuals.
HydroCAD combines the most-used capabilities of TR-20 and TR-55, plus many other techniques and features not provided by either program. We also have a step-by-step guide for comparing the results from these programs.
