The introduction and advancement of spatial information technologies such as remote sensing and geographic information systems (GIS) have provided many (software) tools that assist in natural resource planning and management. GIS technology has particularly provided many cost-effective tools for evaluating land use/land cover (LU/LC) and the implications of different land use practices within a...

In the Loess Plateau, soil erosion has not only caused serious ecological and environmental problems but has also impacted downstream areas. Therefore, a model is needed to guide the comprehensive control of soil erosion. In this study, we introduced the WEPP model to simulate soil erosion both at the slope and watershed scales. Our analyses showed that: the simulated values at the slope scale ...

The Donghe basin is one of the typical regions with serious water and soil erosion in Kaixian county of China. In this study the spatial distribution variation of soil erosion in Donghe basin is analyzed based on a comprehensive method that integrates SWAT model with a Geographic Information System and remote sensing technologies and the effects of land use changes on soil erosion is also analy...

Organic amendments such as composts and mulches have been shown to improve soil quality and reduce the impacts of stormwater runoff and soil erosion Previous studies using rainfall simulators have documented that runoff volumes and soil erosion can be significantly reduced when organic materials are added to the soil profile. The objectives of this study are to measure the changes in runoff and...

Most runoff and soil erosion models take into account rainfall intensity, since higher storm intensities lead to greater runoff and losses of soil due to erosion. Accurate prediction of soil erosion requires rainfall intensity data with a high temporal resolution. This places a restriction on the simulation of soil erosion, since high temporal resolution data are usually not available. One way ...

Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...

abstract surface soil shear strength is an effective parameter in soil erosion and runoff modeling, and known as soil erodibility index. this study was conducted to investigate and predict soil shear strength in central zagros region using multiple linear regressions (mlr). the study site was selected in rangeland and degraded-rangeland landuse with an area of 23562 ha. based on the maps of geo...
