The United States Natural Resources Conservation Service (NRCS) Runoff Curve Number (CN) is the most widely used rainfall-runoff modeling method. The hydrologic soil group (HSG), land use/cover, hydrologic surface condition and antecedent moisture condition jointly determine the CN value. This study...
A modification to the Soil Conservation Service curve number method for steep slopes in the Loess Plateau of China The Soil Conservation Service curve number (CN) method is widely used for predicting direct runoff from rainfall. However, despite the extent of cultivatio... Huang,MB,Gallichand,....
This work proposes an approach to automatically adjust the curve number (CN) to account for changes in vegetation density. Precipitationrunoff pairs from the MOdel Parameter Estimation EXperiment (MOPEX) dataset were used to estimate monthly simulated CNs (CNsim). Remotely sensed greenness fraction (...
Curve numbertyphoon eventrunoffdisaster riskThe NRCS-CN method is widely applied in the estimation of precipitation runoff. It primarily relies on soil mapping and land use data as input parameters, although land use data is not frequently updated. This study replaced such data with land cover ...

The NRCS curve number method is at the core of many rainfall-runoff models in hydrology. As a simple lumped parameter method, it is often scrutinized because it is not obvious how to derive S from catchment hydromorphological characteristics. The novel approach provides a clear physical meaning ...
