Estimation of rainfall-induced surface runoff for the Assam region, India, using the GIS-based NRCS-CN method
نویسندگان
چکیده
The NRCS-CN method, integrated with GIS and remote sensing, can be used for estimating curve numbers (CN) surface runoff in geohydrological systems. study area is divided into 63 sub-basins, the land use cover (LULC)-hydrologic soil group (HSG) complex identified each sub-basin. CN values three antecedent moisture (AMC) conditions are calculated corrected slope variations. depth determined using rainfall data 16 years (2005–2020). average mean annual precipitation ranges from 444.50 to 1960.55 mm 936.99 3520.55 mm, respectively. For all strong correlations between (R2 ≥ 0.8) as well simulated measured observed. Nash–Sutcliffe model efficiency coefficient (NSE) suggest that model's good satisfactory.

One of the major problems confronted by the hydrologists for many years is the prediction of runoff from a given basin for a known rainfall. In this situation, development of a rainfall runoff model is important in Veeranam tank catchment located at latitude 11° 15’00” and longitude 79° 30’00’ E in Cuddalore District of Tamilnadu, India. By considering the above said aspect the rainfall-runoff ...
