Soil Erosion Estimation Using Grid-based Computation Soil erosion estimation is an important part of a land consolidation process. Universal soil loss equation (USLE) was presented by Wischmeier and Smith. USLE computation uses several factors, namely R – rainfall factor, K – soil erodability, L – slope length factor, S – slope gradient factor, C – cropping management factor, and P – erosion co...

The paper has the goal to evaluate if the Universal Soil Loss Equation (USLE)applied using thematic paper maps and a DEM is sufficient to generate a model to map and predict the influences on the environment caused by soil erosion on Loess Plateau. Factors of USLE R, K, S, L, P as well as C were adapted to the test area, the Nihe Gou catchment in Chunhua County in Shaanxi. Afterwards the parame...

According to a UN Environment Programme survey, topsoil is eroding faster than it forms on about one third of the world’s cropland, causing an estimated 85 % of the world s land degradation from human activities. Erosion of soil, mainly by water, is also a problem in the Czech Republic where 54 % of arable land is endangered by water erosion. The topic of this article is to describe contemporar...

The focus of soil erosion research in the Alps has been in two categories: (i) on-sitemeasurements, which are rather small scale point measurements on selected plots often constrained to irrigation experiments or (ii) off-site quantification of sediment delivery at the outlet of the catchment. Results of both categories pointed towards the importance of an intact vegetation cover to prevent soi...

the soil erodibility factor varies spatially according to variations of some soil properties on the surface. this study was carried out to compare spatial variability of the soil erodibility factor as estimated and measured using the usle. the study was conducted in an agricultural zone with an area of in 900 km2 in hashtrood, northwestern iran. in the study area, 36 square grids with a dimensi...
