Comments: 1) TR-20 is a computer program for the generation and routing of runoff hydrographs. Unlike TR-55, which was developed for manual use, the calculations in TR-20 are far too complex and numerous to be of practical use without appropriate computer software.
10 Φεβ 2018 · We have emailed SCS numerous times and there is always an automated response promising contact within 24-48 hours. We never receive any communication! We believe we were missold this extra warranty and want to be reimbursed for this.
HydroCAD, TR-20, TR-55 Comparison. The following table summarizes the technical similarities and differences between these three programs. HydroCAD combines the most-used capabilities of TR-20 and TR-55, plus many other techniques and features not provided by either program.
Solution. 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.
