Technical Release 55 (TR-55) presents simplified procedures for estimating runoff and peak discharges in small watersheds. In selecting the appropriate procedure, consider the scope and complexity of the problem, the available data, and the acceptable level of error. While this TR gives special emphasis to urban
Urban Hydrology for Small Watersheds – TR-55. Technical Release 55 (TR-55) presents simplified procedures to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes required for floodwater reservoirs.
While the TR-55 manual remains a most useful reference (it contains complete curve number tables and rainfall maps, among other things) most engineers have sought out more advanced or more accurate hydrology software. How to get it: You can download the TR-55 Manual here. (2MB PDF format) You can download the complete software and documentation ...
Tc is computed by summing all the travel times for consecutive compo-nents of the drainage conveyance system. Tc influences the shape and peak of the runoff hydrograph. Urbanization usually decreases Tc, thereby increasing the peak discharge.
NRCS TR55 - Small Watershed Hydrology. advertisement. WinTR-55: Introduction and Background. Objectives: • The basics. • History of WinTR-55. • Nuts & bolts of algorithms. • Demo of model interface.
19 Ιουλ 2004 · WinTR-55 uses the TR-20 (NRCS, 2002) model for all of the hydrograph procedures: generation, channel routing, storage routing, and addition. Figure 1 is a diagram showing the WinTR-55 model, its relationship to TR-20, and the files associated with the model. Figure 1.

2 Μαΐ 2016 · Technical Release 55 (TR-55) Urban Hydrology for Small Watersheds was first issued in January 1975 as a simplified procedure to calculate the storm runoff volume, peak rate of discharge, hydrographs and storage volumes required for storm water management structures (SCS, 1975).
