Webb5 juli 2024 · This study used the Soil Conservation Service Curve Number (SCS-CN) method integrated with remote sensing and Geographic Information Systems (GIS) techniques to estimate urban runoff and to study the impact of the land use\land cover changes on surface runoff rates between 1989 and 2024. WebbThe new model out-performed the Asymptotic runoff model and SCS CN runoff model with low predictive model bias, reduced sum of squared errors by 32% and achieved high Nash-Sutcliffe efficiency value of 0.96. The derived urban curve number is 98.0 with 99% confidence interval ranging from 97.8 to 99.5 for Sungai Kerayong catchment. hello kitty plush toy australia
