Effect Of Slope Adjustment On Curve Number Using Global Digital Elevation Data: New Look Into Sharply-Williams And Huang Methods

Effect Of Slope Adjustment On Curve Number Using Global Digital Elevation Data: New Look Into Sharply-Williams And Huang Methods

The Natural Resources Conservation Service Curve Number (NRCS-CN) method is highly recommended for runoff prediction in many climate conditions. The key parameters to obtain CN values are hydrologic soil groups and land use information with respect to soil moisture conditions. This method has been w...
