Scs type storm
Webb2 maj 2024 · WinTR-55 is a single-event rainfall-runoff small watershed hydrologic model. The model generates hydrographs from both urban and agricultural areas and at selected points along the stream system. Hydrographs are routed downstream through channels and/or reservoirs. Multiple sub-areas can be modeled within the watershed. Technical … Webb16 feb. 2009 · If you have access to a copy of TR-55, there is a figure in it which shows the rainfall distributions for the Type I, Type IA, Type II and Type III standard SCS storms. The six-hour ESH distribution which used to be in TR-60 is very similar to the middle six hours of the Type I storm. We think that is its origin.
