Green-Ampt infiltration model parameter determination using SCS curve number (CN) and soil texture class, and application to the SCS runoff model
The U.S. Department of Agriculture (USDA) Soil Conservation Service Curve Number (SCS CN) method is a simple and widely popular technique of estimation of direct runoff volume for design and natural rainfall events in small watersheds. The SCS CN procedure is incorporated into such computer …

Hydrological Analysis of an Urban Basin in Sub-Tropical Environment
… are used to delineate the sub-basins and the Soil Conservation Service Curve Number (SCS-CN) map of the basin. The SCS-CN hydrograph method is used in HEC-HMS model to simulate infiltration losses and the watershed response to the different storm cases. The simulations are conducted using …

Improved Understanding Of Subsurface Hydrology In Variable Source Areas And Its Implications For Water Quality
… tier of New York, U.S. Water flux from different soil layers in the trench and upslope water table dynamics were recorded for 16 events and isotopic and geochemical tracers were measured during five events. In conjunction with the surface and bedrock topography these measurements allowed detailed …

Flood risk assessment using multi-sensor remote sensing, geographic information system, 2D hydraulic and machine learning based models
… modern Taguchi method. Then, a GIS -based soil conservation service-curve number (SCS-CN) model was developed to simulate the maximum probable surface runoff. Results showed that deforestation and urbanisation have occurred upon a given time and have been predicted to increase. Furthermore, …

Development and evaluation of a watershed-scale hybrid hydrologic model
… excess rainfall estimated with the SCS curve number method and a GIS-based set of separated unit hydrographs (spatially distributed unit hydrograph) are utilized to calculate a direct runoff flow hydrograph, and time-varied SCS CN values and conditional unit hydrograph approach for …
