Surface runoff estimation of Wadi Ba Al-Arid watershed North East Libya, using SCS-CN ,GIS and RS data
The aim of this study is to estimate runoff in Wadi Ba Al Arid watershed for a period of ten years 2009-2018 by Soil Conservation Service Curve Number (SCS-CN) method in combination with the GIS techniques using remote sensing data. The used data are the daily rainfall data from NASA Prediction of Worldwide Energy Resource (POWER), digital elevation data (DEM) from ALOS PALSAR RTC , satellite...
متن کاملEstimation of Runoff using Modified SCS Models
In recent decades, due to the importance of watershed management programs and the need for adequate information and correct estimation of rainfall and runoff, many conceptual models have been proposed. These models have parameters that must be estimated according to observational data. However, finding the optimal values for the parameters of simulation models has always faced uncertainty. One ...
متن کاملSCS-CN parameter determination using rainfall-runoff data in heterogeneous watersheds – the two-CN system approach
The Soil Conservation Service Curve Number (SCS-CN) approach is widely used as a simple method for predicting direct runoff volume for a given rainfall event. The CN parameter values corresponding to various soil, land cover, and land management conditions can be selected from tables, but it is preferable to estimate the CN value from measured rainfall-runoff data if available. However, previou...

15 صفحه اولThe effects of watershed management practices on runoff production using SCS model in Anbaranchay watershed
Watershed management has different effects on the amount of runoff and sediment and alteration ofhydrological features in a watershed. In this study, the effects of watershed management on runoff was investigated in the Anbaranchaywatershed. For this purpose, the topography data in format of a digital elevation model, land use, soil hydrological groups and watershed managemetrigeon,and also usi...
