CN method is a commonly used technique for estimation of direct runoff for flood mitigation studies. In Saudi Arabian (SA) arid basins, there is no analysis of NRCS-CN obtained from measured rainfall-runoff events. The research objectives are to find out the actual range of CN values in ...
The 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 classes based on satellite images, and ...
The NRCS-CN method achieved an R2 of 0.37, whereas the ANN model significantly improved the predictive accuracy, achieving an R2 of 0.88. This substantial increase demonstrates the ANN model's superior ability to capture the complexities of daily runoff dynamics compared to the NRCS-CN method. ...
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...

NRCS-CN method and SHETRAN model was used to find runoff depth.Monthly Runoff was calculated using NRCS-CN model and daily runoff computed for each catchment using SHETRAN for the year 2012. Landsat 7 (with resolution 30 m) satellite data for the year 2012 has been used for the ...
The traditional NRCS-CN method for calculating the composite curve number is very tedious and consumes a major portion of the hydrologic modeling time. Therefore, geographic information systems (GIS) are now being used in combination with the NRCS-CN method.NRCS-CN method is accepted and used ...
