Gis Based Scs Cn Method For Estimating Runoff In Pdf Drainage In this study, gis based modiied scs cn method was applied to estimate runoff values for the ambika and purna watersheds of the dang district of gujarat. In this study we are considering scs cn method along with geographic information technique for calculating surface runoff volume. it is the most common method to estimate the runoff which was developed by united states department of agriculture (usda) soil conservation service (scs, 1985).
Runoff Calculation By Using Scs Cn Method Download Table In this paper, modified soil conservation system (scs) cn method is used for runoff estimation that considers parameter like slope, vegetation cover, area of watershed. As been taken as case study for the estimation of runoff by scs curve number method using geo spatial technology. direct runoff depends on rainfall, soil type, soil moisture, drainage density, topography, size and shape of water. Scs cn method developed by soil conservation services (scs) of usa in 1969 is a simple, predictable and stable conceptual method for estimation of direct runoff depth based on storm rainfall depth. In this study gis based scs curve number method was used to estimate runoff from the ungauged watershed. based on the results of soil classification and land use, the study area was classified into three hydrologic soil groups.
Pdf Estimation Of Surface Runoff Potential Using Scs Cn Method Scs cn method developed by soil conservation services (scs) of usa in 1969 is a simple, predictable and stable conceptual method for estimation of direct runoff depth based on storm rainfall depth. In this study gis based scs curve number method was used to estimate runoff from the ungauged watershed. based on the results of soil classification and land use, the study area was classified into three hydrologic soil groups. This needs to be taken into account of rainfall runoff modeling and thus in the delineation of the areas. the input parameters which influence runoff component vary spatially at micro levels. a runoff model has been developed on the basis of scs cn method in the present study for predicting runoff. Use of remote sensing and gis technology can be useful to overcome the problem in conventional methods for estimating runoff. in this paper, modified soil conservation system (scs) cn. In the present study, for east godavari dist. runoff estimation is concluded by using soil conservation service curve number (scs cn) method and application of geographical information system(gis) using landsat 8 series satellite images in 11 bands and developed various rasters through arc gis 10.5. This research focuses on estimating surface runoff over the lower vellar basin, a river basin in the southern part of india, by integrating soil conservation service curve number (scs cn) method with gis.
