Theory-Based SCS-CN Method and Its Applications

Journal of Hydrologic Engineering, 2010
This study, by incorporating the Philip infiltration solution, constructs from a theoretical perspective an alternative model to replace the Soil Conservation Service curve-number (SCS-CN) method and provides an in-depth analysis of its variants in order to understand their limitations and accuracy.

Improved SCS-CN Method Based on Storage and Depletion of Antecedent Daily Precipitation

Water Resources Management, 2015
The accurate simulation or prediction of storm runoff is one of the most important bases of water resource management and environmental quality assessment of water and soil. The soil conservation service-curve number (SCS-CN) method cannot effectively determine the effect of antecedent precipitation storage and depletion on runoff, which limits the ...

A simplified GIS-based SCS-CN method for the assessment of land-use change on runoff

Arabian Journal of Geosciences, 2018
The purpose of this study is to evaluate the impact of land-use alteration over years on potential runoff volumes for the Gaza Strip. The runoff curve number (CN) is an important factor to calculate the runoff volume in the standard Soil Conservation Service (SCS) method.

Runoff Estimation Using SCS CN Method For Kelantan River Basin

, 2015
Runoff is one of the basic and crucial hydrological data which is needed in the water resources planning and management e.g. flood mitigation measures, waterways, and storage capacity and erosion control.

Another Look at SCS-CN Method

Journal of Hydrologic Engineering, 2001
The Soil Conservation Service-curve number (SCS-CN) method is analytically derived and its basis in the Mockus method analyzed. A modification and a general form of the SCS-CN method are proposed. Using data from five watersheds, the existing SCS-CN method, the proposed modification, and the Mockus method are compared.

SCS-CN Method

2003
The Soil Conservation Service Curve Number (SCS-CN) method was developed in 1954 and is documented in Section 4 of the National Engineering Handbook (NEH-4) published by the Soil Conservation Service (now called the Natural Resources Conservation Service), U.S. Department of Agriculture in 1956.

Analytical Derivation of the SCS-CN Method

2003
Since the inception of the SCS-CN method, the issues such as the rational derivation of the method (equation (2.5)), the rationale of initial abstraction, the analytics of the S-CN mapping relation (equation (2.7)), and the CN-AMC relations have been of major concern.

Initial Abstraction Ratio in the SCS-CN Method in the Loess Plateau of China

Transactions of the ASABE, 2011
The Soil Conservation Service curve number (SCS-CN) method is widely used to predict runoff because of its simplicity. The initial abstraction ratio (λ), which is assumed to have a default value of 0.2 in the SCS-CN method, is an important influence factor for runoff estimation. A more reasonable value may improve the performance of this method.

SCS-CN Method Revisited Using Entropy Theory

Transactions of the ASABE, 2013
Abstract. The SCS-CN method is one of the most popular methods for computing runoff from small watersheds (agricultural, forest, rural, and urban) for individual rainfall events. This study revisits the method using the entropy theory, which provides insights into the structure of the method and permits derivation of the probability distributions of

Estimation of surface runoff in Malattar sub-watershed using SCS-CN method

Journal of the Indian Society of Remote Sensing, 2009
Nowadays watershed management plays a vital role in water resources engineering. Watershed based on water resources management is necessary to plan and conserve the available resources. Remote Sensing (RS) and Geographic Information System (GIS) techniques can be effectively used to manage spatial and non spatial database that represent the hydrologic ...
