A Modified SCS-CN Method: Characterization and Testing
Water Resources Management, 2003The Soil Conservation Service Curve Number (SCS-CN) method (SCS,1956) is modified by accounting for the static portion ofinfiltration and the antecedent moisture. A volumetric analysisshows that the ratio of the potential maximum retention (S) tothe precipitation amount versus the runoff factor relation isequivalent to the average suction pressure ...

Modifications to SCS-CN Method for Long-Term Hydrologic Simulation
Journal of Irrigation and Drainage Engineering, 2007The original soil conservation service curve number (SCS-CN) technique is primarily used to transform daily rainfall into surface runoff by assuming the proportionality between retention and surface runoff based on a parameter referred to as curve number (CN).

Analytical Derivation of the SCS-CN Method
2003Since 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, 2011The 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, 2013Abstract. 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, 2009Nowadays 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 ...

Estimation of Surface Runoff Using GIS Based SCS – CN Method
Agriculture Association of Textile Chemical and Critical ReviewsWater, which is one of the crucial natural resources on the earth, is becoming scarce and there is an ever-increasing need to conserve the water resources. Efficient management of water requires accurate estimation of runoff from the watershed. There are numerous conventional methods available to estimate runoff depth and volume from a given watershed.

Runoff Volume Estimation by SCS-CN Method Through Arc-GIS Approach
2020The salient resources of water for discharge of groundwater in a watershed or catchment area are rainfall and rainfall runoff. The primary source of groundwater recharge is rainfall. Runoff in the watershed or catchment area affected by geomorphologic feature principally, land use change affects the surface runoff volume over and rate of runoff ...

Estimation of Runoff in the Manas River Catchment using SCS-CN Method
Ecology, Environment and ConservationRunoff estimation is crucial for effective water resource management and land use planning in river catchments. In this study, we applied the Soil Conservation Service Curve Number (SCS-CN) method to estimate runoff in the Manas River catchment and nearby areas.
