introduction rainfall erosivity, the propulsion or power of causing erosion in separation and transport of soil particles, is in relation to water erosion. rainfall erosion is causing loss of soil, damage to agriculture and infrastructures which is followed by water pollution. changes in rainfall patterns exacerbate risk of erosion globally. rainfall erosivity plays an effective role in soil er...

Soil erosion can be considered as one of the most important obstacles in the way of sustainable development of agriculture and natural resources. The aim of this study is to estimate erosion and sediment yield of basin using Erosion Potential Method, in Gorganrud basin, north of Iran. The main factors in the EPM (slope average percent, erosion, rock and soil resistance, and land-use) were evalu...

According to the IPCC, global temperatures are expected to increase between 1.1 and 6.4 °C during the 21st century and precipitation patterns will be altered. Soils are intricately linked to the atmospheric/climate system through the carbon, nitrogen, and hydrologic cycles. Because of this, altered climate will have an effect on soil processes and properties. Recent studies indicate at least so...

The REGFLUD-project, commissioned by Germany's Federal Research Ministry (BMBF), addresses the problem of reducing diffuse pollution from agricultural production. The objective of the project is the development and application of multi-criteria scientific methods, which are able to predict diffuse pollution in river basins subject to economic feasibility and social acceptability. The selected r...

The placement of stiff‐stemmed grass hedges on the contour along a hillslope has been shown to decrease nutrient transport in runoff. This study was conducted to measure the effectiveness of a narrow grass hedge in reducing runoff nutrient transport from plots with a range of soil nutrient values. Composted beef cattle manure was applied at dry weights of 0, 68, 105, 142, and 178 Mg ha-1 to a s...

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...
