Theory-Based SCS-CN Method and Its Applications
Journal of Hydrologic Engineering - ASCE, 2010This study, by incorporating the Philip infiltration solution, constructs from a theoretical perspective an alternative model to replace the Soil Conservation Service curve-number (SCS-CN) method and provides an in-depth analysis of its variants in order to understand their limitations and accuracy.

Improved SCS-CN Method Based on Storage and Depletion of Antecedent Daily Precipitation
Water Resources Management, 2015The accurate simulation or prediction of storm runoff is one of the most important bases of water resource management and environmental quality assessment of water and soil. The soil conservation service-curve number (SCS-CN) method cannot effectively determine the effect of antecedent precipitation storage and depletion on runoff, which limits the ...

A simplified GIS-based SCS-CN method for the assessment of land-use change on runoff
Arabian Journal of Geosciences, 2018The purpose of this study is to evaluate the impact of land-use alteration over years on potential runoff volumes for the Gaza Strip. The runoff curve number (CN) is an important factor to calculate the runoff volume in the standard Soil Conservation Service (SCS) method.

The Soil Conservation Service-curve number (SCS-CN) method is analytically derived and its basis in the Mockus method analyzed. A modification and a general form of the SCS-CN method are proposed. Using data from five watersheds, the existing SCS-CN method, the proposed modification, and the Mockus method are compared.

A Modified SCS-CN Method: Characterization and Testing
Water Resources Management, 2003The Soil Conservation Service Curve Number (SCS-CN) method (SCS,1956) is modified by accounting for the static portion ofinfiltration and the antecedent moisture. A volumetric analysisshows that the ratio of the potential maximum retention (S) tothe precipitation amount versus the runoff factor relation isequivalent to the average suction pressure ...

Analytical Derivation of the SCS-CN Method
2003Since the inception of the SCS-CN method, the issues such as the rational derivation of the method (equation (2.5)), the rationale of initial abstraction, the analytics of the S-CN mapping relation (equation (2.7)), and the CN-AMC relations have been of major concern.
