WebbThe SCS CN method estimates precipitation excess as a function of the cumulative precipitation, soil cover, land use, and antecedent soil moisture. The input requirements … Webb3.1 SCS-CN Model In this study, the Soil Conservation Service Curve Number (SCS-CN) model was used to estimate surface runoff for the study area. A stepwise methodology is given in flow chart (Fig. 2). Firstly, the surface runoff was computed on daily basis, which was later on converted to annual surface runoff value for Sixteen years (2001-2016).
Webbuse considering slope for the years 1972, 1989 and 2000 using SCS CN method. Following results were found in their research. i) Slope based CN (SA-CN 2) is less than the normal CN (SCS-CN) when slope is less than 5 % but it is more than SCS-CN when slope is greater than 5%. Higher the deviation from 5% slope more is the difference. Webb9 apr. 2024 · Among these methods, the Soil Conservation Service Curve Number (SCS-CN) method [ 2] is one of the most widely used.

The runoff curve number (also called a curve number or simply CN) is an empirical parameter used in hydrology for predicting direct runoff or infiltration from rainfall excess. The curve number method was developed by the USDA Natural Resources Conservation Service, which was formerly called the Soil Conservation Service or SCS — the number is still popularly known as a "SCS runoff curve number" in the literature. The runoff curve number was developed from an empirical analysis of r…
WebbThus, to give conceptual framework of the SCS-CN model, the event-based Ajmal model was merged with the most commonly used SCS-CN method and a new hybrid model was formulated.
