DEM based Extraction of LS factor: integrate channel networks and convergence flow
LS is a very important factor in erosion evaluation. Slope gradient and slope length is used to calculate LS factor. However a major limitation is the difficulty in extracting the LS factor at regional landscape scales. The geographic information systembased (GIS-based) methods which have been developed for estimating the slope length for USLE and RUSLE model also have limitations. he unit cont...
متن کاملEffect of DEM data resolution on SWAT output uncertainty
This paper describes the effect of DEM data resolution on predictions from the SWAT model. Measured hydrologic, meteorological, watershed characteristics and water quality data from Moores Creek watershed (near Lincoln, AR, USA) were used in the simulation. The effect of input data resolution was evaluated by running seven scenarios at increasing DEM grid sizes (30 ð 30 m, 100 ð 100 m, 150 ð 15...

Topographic factor is an important factor of computer models of USLE family due to the high sensitivity of model results to its variation and complicated effects of topography on soil erosion. Moore and Wilson (1992) have introduced a well-known method to compute LS factor of RUSLE model using digital elevation model (DEM).The objective of this study was to determine the proper cell size of DEM...
متن کاملEvaluation of Erosivity factor in USLE Versions in semi-arid regions of Khorasan
The first step to controlling soil loss, is estimating of soil erosion amount. Universal soil loss Equation is One of the ways is widely used to estimate erosion, in which the absence of long term data. Effective force in the development of various forms of erosion is the power erosivity of runoff and rainfall and are expressed in erosivity index. This study aimed to evaluate the erosivity Inde...
