The greatest obstacle to soil erosion modelling at larger spatial scales is the lack of data on soil characteristics. One key parameter for modelling soil erosion is the soil erodibility, expressed as the K-factor in the widely used soil erosion model, the Universal Soil Loss Equation (USLE) and its revised version (RUSLE). The K-factor, which expresses the susceptibility of a soil to erode, is...

Soil erosion forms a major threat to European soil resources. Although soil is a vital and largely non-renewable resource, it has not been the subject of comprehensive EU action so far. A thematic strategy for soil protection, which recognises soil erosion as one of the major threats, has currently been placed high on Europe’s political Agenda. Assessing and monitoring soil erosion is needed to...

The effects of water erosion (including long-term historical erosion and single erosion event) on soil properties and productivity in different farming systems were investigated. A typical sloping cropland with homogeneous soil properties was designed in 2009 and then protected from other external disturbances except natural water erosion. In 2012, this cropland was divided in three equally siz...

Astract: This paper shows how recent situation of soil erosion evaluation and prediction on a regional scale based on the techniques of spatial information. The study, which was carried out in central China, identified sediment discharge, precipitation, soil composition, gully density and land use as erosion factors at the regional level. It showed that soil erosion can be assessed and predicte...

This paper estimates the soil erosion rate and erosion-induced carbon sink using a new approach, and distinguish the contribution from topsoil erosion, gully erosion and landslides. The role of conservation programs on reducing soil erosion is also assessed. Special comments: 1. The abstract is too long and needed to be simplified. Besides, as the soil erosion rate estimated in this paper is mu...

Century-long studies on the impacts of forest management in North America suggest sediment can cause major reduction on stream water quality. Soil erosion patterns in forest watersheds are patchy and heterogeneous. Therefore, patterns of soil erosion are difficult to model and predict. The objective of this study is to develop a user-friendly management tool for land managers to design forest m...

Soil erosion/sedimentation is an immense problem that has threatened water resources development in the Nile river basin, particularly in the Eastern Nile (Ethiopia, Sudan and Egypt). An insight into soil erosion/sedimentation mechanisms and mitigation methods plays an imperative role for the sustainable water resources development in the region. This paper presents daily sediment yield simulat...
