What is the SCS CN method?
The SCS-CN method predicts runoff from an expression for a rainfall-runoff curve that varies according to a single parameter called the curve number (CN). The dimensionless CN parameter describes the antecedent potential water retention of a watershed [Hawkins, 2014].
What are the SCS CN method of estimating runoff volume?
Soil Conservation Service – Curve Number (SCS – CN) method is employed to estimate the runoff. It is one of the physical based and spatially distributed hydrological models. In this model, the curve number is a primary factor used for runoff calculation.
Is SCS the same as TR-55?
First issued by the Soil Conservation Service (SCS) in January 1975, TR-55 incorporates current SCS procedures. This revision includes results of recent research and other changes based on experience with use of the original edition.
What is the full form of SCS CN *?
Soil Conservation Services and Curve Number (SCS–CN) technique is one of the primogenital and simplest method for rainfall runoff modelling.
What is the SCS TR 55 method?
Technical Release 55 (TR-55) presents simplified procedures to calculate storm runoff volume, peak rate of discharge, hydrographs, and storage volumes required for floodwater reservoirs. These procedures are applicable in small watersheds, especially urbaniz- ing watersheds, in the United States.
What does SCS stand for?

What is the SCS Curve Number method?
The SCS curve number method is a simiple, widely used and efficient method for determining the approxient amount of runoff from a rainfall even in a particular area.
What is the SCS-CN method used for?
A modified SCS-CN method was used for runoff estimation, considering parameters like slope, vegetation cover and watershed area [8]. The underestimation of runoff due to CN composition is most severe for wide CN ranges, low CN values, and low precipitation depths [9]. …
Is modified soil conservation system (SCS) CN method useful for runoff estimation?
In this paper, modified Soil Conservation System (SCS) CN method is used for runoff estimation that considers parameter like slope, vegetation cover, area of watershed. The Land cover map developed for the study region was used in analyzing the runoff generated over the command area.
What are the types of research methods in social science?
There are two main groups of research methods in the social sciences: The empirical-analytical group approaches the study of social sciences in a similar manner that researchers study the natural sciences. The interpretative group of methods is focused on understanding phenomenon in a comprehensive, holistic way.
