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 the...

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 hydrologic soil …

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.

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 detention or …

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 excess from 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 can …

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 given duration and …

The Soil Conservation Service (SCS) proposed a parametric Unit Hydrograph (UH) model. The model is based upon averages of UH derived from gaged rainfall and runoff for a large number of small...

Jun 11, 2025 · In this article, we'll explore the basics of the SCS Curve Number Method, its practical applications, and provide tips for effective implementation.

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 SCS) unit …
