The Soil Conservation Service (SCS) Curve Number (CN) model estimates precipitation excess as a function of cumulative precipitation, soil cover, land use, and antecedent moisture, using …

It is widely used and is an efficient method for determining the approximate amount of direct runoff from a rainfall event in a particular area. The runoff curve number is based on the area's …

How do the Rational method and the SCS method stack up against each other? If you’re a civil engineer working on urban stormwater modeling, you’ve probably pondered this classic dilemma.

It is an empirical method that expresses how much runoff volume is generated by a certain volume of rainfall. The variable input parameters of the equation are the rainfall amount for a …

Jun 4, 2025 · The SCS (Soil Conservation Service) Runoff Method, also known as the NRCS Method, provides an alternative, especially useful for calculating runoff volume and sizing …

The SCS Runoff Curve Number method is developed by the United States Department of Agriculture (USDA) Soil Conservation Service (SCS) and is a method of estimating rainfall …

The SCS Method is described in great detail in the USDA publication "Urban Hydrology for Small Watersheds", otherwise known as TR-55. Despite the title of this publication, the SCS Method …

E-mail: [email protected] ABSTRACT The SCS (or NRCS) method, arising in the 1950’s out of analysis of real data from large numbers of catchments across the USA, is one …

To match the runoff depth given by the SCS runoff equation, the time span must include all times at which runoff will occur.

Aug 8, 2022 · The US SCS Method Hydrological Boundary is a hydrological model for determining runoff from rainfall for a subcatchment using the United States Soil Conservation Service (US …
