WebbPervious curve numbers play a major role in storm water management as a key component of hydrologic and hydraulic modeling for floodplain analysis. Curve numbers (CN) for various land-use classifications have been published by the U.S. Soil Conservation Service (SCS 1986) for each of the four hydrologic soils groups (A, B, C, and D). Webb11 apr. 2024 · Rainfall and runoff are the essential hydrologic parameters when estimating water resources. This study aims at estimating surface runoff on the Padma river basin based on the SCS-CN method in a geographic information system (GIS) and remote sensing (RS) environment.
