The main scope of this research is evaluation of Soil Conservation Service Procedure in derivation of initial abstraction of precipitation in watershed scale. For this purpose Dalaki watershed which is located in south east of Iran was selected then by using hec-hms and GIS models and a number of observed rainfall runoff events some parameters like CN of watershed ,K and X of Muskingam meth...

The Curve Number (CN) rainfall–runoff model is a widely used method for estimating the amount of rainfall and runoff, but its accuracy in predicting runoff has been questioned globally due to failure produce precise predictions. was developed by United States Department Agriculture (USDA) Soil Conservation Services (SCS) 1954, data documentation about development are incomplete, making it diffi...

Simulation of the runoff-rainfall process in forest lands is essential for land management. In this research, a hydrologic modelling system (HEC-HMS) and artificial neural network (ANN) were applied to simulate rainfall-runoff (RRP) Kasilian watershed with an area 68 square kilometres. The HMS model was performed using secondary data rainfall discharge at climatology hydrometric stations, Soil ...

Abstract Cimahi City as a part of the Upper Citarum Sub-Watershed has problems with flooding, land subsidence, and clean water crisis caused by urban development. Currently, multidisciplinary approach to management been expanded include hydrological cycle in it; one concepts that developed is water-sensitive design (WSUD). The purpose this study measure changes surface runoff result infiltratio...

Runoff potentiality of a watershed was assessed based on identifying curve number (CN), soil conservation service (SCS), and functional data analysis (FDA) techniques. Daily discrete rainfall data were collected from weather stations in the study area and analyzed through lowess method for smoothing curve. As runoff data represents a periodic pattern in each watershed, Fourier series was introd...

The Gully Land Consolidation (GLC) project, aiming to create land for agriculture on the Loess Plateau, heavily interfered with underlying surface and thus affected hydrological process. purpose of this study was investigate effects GLC runoff peak flow rates watershed Plateau under different rainfall events years. A GIS-based Soil Conservation Service Curve Number (SCS-CN) model used. results ...

An investigation of soil and water resources is essential to determine the future scenario management attain food security. The improper watersheds results in a huge amount sediment loss surface runoff. Therefore, present study was carried out estimate runoff erosion using Soil Conservation Service Curve Number (SCS-CN) method RUSLE approach, respectively. These have been estimated geospatial t...

One of the major problems confronted by the hydrologists for many years is the prediction of runoff from a given basin for a known rainfall. In this situation, development of a rainfall runoff model is important in Veeranam tank catchment located at latitude 11° 15’00” and longitude 79° 30’00’ E in Cuddalore District of Tamilnadu, India. By considering the above said aspect the rainfall-runoff ...
