    The Soil Conservation Service curve number estimates of direct runoff from rainfall for semiarid catchments can be inaccurate. Investigation of the Walnut Gulch Experimental Watershed (Southeastern Arizona) and its 10 nested catchments determined that the inaccuracy is due to an unsuspected relationship between initial abstraction and maximum potential retention.

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.

The Soil Conservation Service (SCS) curve number (CN) method is one of the most popular methods for computing the runoff volume from a rainstorm.

It is popular because it is simple, easy to understand and apply, and stable, and accounts for most of the runoff producing watershed characteristics, such as soil type, land use, hydrologic condition Cited by:   Soil Conservation Service Curve Number (SCS-CN) Methodology (Water Science and Technology Library Book 42) - Kindle edition by Mishra, S.K., Singh, V.P.

It is based on a tremendous amount of experimental work, has been widely used in the United States and across the world, and has more recently been integrated into several rainfall-runoff models.

In a recent. The results were favorable with r2 = and e = INTRODUCTION The Soil Conservation Service (SCS) runoff curve number method is a well accepted technique in applied hydrology for determining runoff from the rainfall on a watershed. The surface runoff volume was computed using curve number method developed by the Soil Conservation Service Curve Number (SCS-CN) of the United States Department of Agriculture ().(1) Q = (P − S) 2 P + S Where, Q = the runoff volume (mm); P = Average daily precipitation (mm); S = potential maximum retention after runoff begins (mm) and is correlated to the soil and.

Thus, when using the Soil Conservation Service-Curve Number (SCS-CN) method, the initial abstraction ratio should be locally verified, and the conditions for the application of the suggested value of should be established.

Condition: New. Language: English. Brand new Book. The Soil Conservation Service (SCS) curve number (CN) method is one of the most popular methods for computing the runoff volume from a rainstorm. The Soil Conservation Service curve number (CN) method commonly uses three discrete levels of soil antecedent moisture condition (AMC), defined by the 5‐day antecedent rainfall depth, to describe soil moisture prior to a runoff event.

However, this way may not adequately represent soil water conditions of fields and watersheds in the Loess. The NRCS Curve Number, a New Look at an Old Tool Lawrence A.J. Fennessey, Ph.D., P.E.

* and Richard H. Hawkins, Ph.D., P.E.** Abstract This paper reviews the Natural Resource Conservation Service Curve Number (CN) which is commonly used as the rainfall to runoff transformation term for small watershed hydrologic analyses. Soil Conservation Service Curve Number (SCS-CN) is a popular surface runoff prediction method because it is simple in principle, convenient in application, and easy to accept.

However, the method still has several limitations, such as lack of a land slope factor, discounting the storm duration, and the absence of guidance on antecedent moisture conditions. In this study, an equation was.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 (Hjelmfelt, ).

The method is described in detail in National Engineering Handbook ().The Soil Conservation Service (SCS) curve number (CN) method is one of the most popular methods for computing the runoff volume from a rainstorm.

The SCS-CN method was first published in in Section-4 of the National Engineering Handbook of Soil Conservation Service (now called the Natural Resources Conservation Service), U.
