Abstract: Raindrop impact is a major agent of soil erosion, and any reduction in its effectiveness reduces sediment production from burned watersheds. A chaparral soil treated with heatshock f...

The Wind Erosion Prediction System (WEPS) is a process-based model that simulates daily weather and field conditions along with hourly wind speeds and erosion. Its physical basis should allow model application to regions outside the US for which it was originally developed. The objective of this study was to compare results from measured wind erosion with simulated soil losses as a first exampl...

To better understand the effects of biological soil crusts (BSCs) on soil moisture and wind erosion and study the necessity and feasibility of disturbance of BSCs in the Mu Us sandland, the effects of four treatments, including moss-dominated crusts alone, Artemisia ordosica alone, bare sand, and Artemisia ordosica combined with moss-dominated crusts, on rainwater infiltration, soil moisture, a...

A remote sensing approach towards modelling the land cover pattern for controlling local soil erosion based on the universal soil loss equation (USLE) was developed. The approach was used to analyse the possible impact of land cover changes on local ecological security. Then, land cover pattern optimization aiming at the reduction of local soil erosion was taken. Results show that this method c...

Despite a multitude of studies, overall erosion rates as well as the contribution of different erosion processes on Chinese Loess Plateau (CLP) remain uncertain, which hampers a correct assessment of the impact of soil erosion on carbon and nutrient cycling as well as on crop productivity. In this paper we used a novel approach, based on field evidence, to reassess erosion rates on the CLP befo...

soil erosion is a serious problem especially in northern parts of iran. one themost important side effects on soil erosion may be the decline in qualities of soil refers toagricultural productivity. so it is very important to assess the soil erosion risk for thesustainable development of agriculture. this study outlines ways undertaken to provide anew tool to manage water erosion from physical ...

The proportionality between raindrop-driven soil erosion delivery and area of soil exposed to raindrops under a uniform precipitation rate was investigated in terms of individual size classes using laboratory flume experiments. In particular, we examined the dependence of soil erosion on the area exposed to raindrop detachment. Twelve experiments were performed on the same laboratory flume, fil...
