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 ...

Estimation of Surface Runoff Using GIS Based SCS – CN Method

Agriculture Association of Textile Chemical and Critical Reviews
Water, 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

2020
The 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 ...

A Modified LAPSUS Model to Enhance the Effective Rainfall Estimation by SCS-CN Method

Water Resources Management, 2018
In this study, LAPSUS model is modified to enhance the effective rainfall estimation by SCS curve number method. The LAPSUS model calculates discharge based on effective rainfall and routs it towards lower neighbouring grid cells following the multiple flow direction principle.

Estimation of Runoff in the Manas River Catchment using SCS-CN Method

Ecology, Environment and Conservation
Runoff 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.

Validity and extension of the SCS‐CN method for computing infiltration and rainfall‐excess rates

Hydrological Processes, 2004
AbstractA criterion is developed for determining the validity of the Soil Conservation Service curve number (SCS‐CN) method. According to this criterion, the existing SCS‐CN method is found to be applicable when the potential maximum retention, S, is less than or equal to twice the total rainfall amount.

Influence of coarse soils with high hydraulic conductivity on the applicability of the SCS-CN method

Hydrological Sciences Journal, 2016
ABSTRACTThe impact of the existence of coarse soils with high hydraulic conductivity on the applicability of the Soil Conservation Service curve number (SCS-CN) method is investigated in a heterogeneous catchment in the Zagros mountain region, southwest Iran.
