Soil erosion is one of the most important watershed processe~ in nature, yet quantifying it under field conditions remains a challenge. The lack of soil erosion field data is a major facto r hindering our abi li ty to predict soil erosion in a watershed . We present here the development of a simple and sensitive field method that quantifies soil erosion and the resulting particulate nutrient mo...

Reservoirs are a crucial part of the human water supply system. The effectiveness and service life reservoir is decided mainly by its storage capacity, as such, preventing capacity loss high interest worldwide. Due to climate change in recent years, precipitation types have changed, heavy rainfall events become more severe frequent. Rainfall causes soil erosion slope lands transports large amou...

The Upper Yangtze River Basin comprises a densely-populated agricultural region with mountainous and hilly landforms. Intensive cultivation has been extended onto steep hillslopes, which constitute the principal source area for sediment production. Soil conservation on sloping arable lands is thus of utmost priority for persisting sustainable agricultural production and maintaining sound ecosys...

an erosion hazard index methodology (ehim) was developed for assessing stream erosion. the index of stream erosion is designed as a management tool. assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. the assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. a ...

In Central Aragón (NE Spain), where strong and dry winds are frequent all year round, fallow lands are susceptible to wind erosion due to insufficient crop residues on the surface and loose, finely divided soils by multiple tillage operations. Effects of conventional tillage (CT — mouldboard ploughing followed by a compacting roller) and reduced tillage (RT — chisel ploughing) on soil surface p...
