Vegetation recovery is a promising strategy to mitigate soil loss risk across different landscapes and human disturbance levels. Uncertainties still exist in the impacts of forest restoration on soil ...
Toledo, the southernmost district, is the hub of Belize’s Mayan population, descendants of the ancient Mayan civilization. The Toledo District is primarily inhibited by Kekchi and Mopan Mayans whose...
The influence of deforestation on runoff generation and soil erosion (Case study: Kasilian Watershed)
forest landuse runoff-rainfall model sediment Iran
2015/4/24
Destroying of forest lands and landuse changes have caused undesirable effects in the watershed hydrologic conditions. Landuse and vegetation are important factors in soil erosion and runoff generatio...
Effects of soil depth spatial variation on runoff simulation, using the Limburg Soil Erosion Model (LISEM), a case study in Faucon catchment, France
conditional simulation Faucon hydrograph kriging LISEM soil depth
2015/3/5
Soil depth is an important parameter for models of surface runoff. Commonly used models require not only accurate estimates of the parameter but also its realistic spatial distribution. The objective ...
Surface runoff simulation to mitigate the impact of soil erosion, case study of Třebsín (Czech Republic)
hydrological model shear stress shear velocity soil loss
2015/3/5
The relation between soil erosion and its redistribution on land strictly depends on the process of surface runoff formation during intensive rainfall. Therefore, interrupting and reducing continuous ...
Impacts of land use changes on soil erosion in Pa Deng sub-district, adjacent area of Kaeng Krachan National Park, Thailand
land cover land use changes soil erosion Universal Soil Loss Equation
2015/3/5
Soil erosion has been considered as the primary cause of soil degradation since soil erosion leads to the loss of topsoil and soil organic matters which are essential for the growing of plants. Land u...

Soil erosion from fields located in the hilly lands of Shikoku was investigated. These are the areas where agricultural practices are quite limited and fields are often left idle and unutilized. Based...
Seasonal Changes in the Amount of Litter Layer and Soil Erosion in the Forest Floor:An Impoverished Understory by Deer Impact at Doudaira,Tanzawa Mountains
beech (Fagus crenata) forests browsing impact by sika deer (Cervus nippon) litter soil erosion understory
2009/8/24
Soil erosion has been progressing over a large area in Doudaira (located in East Tanzawa of Kanagawa Prefecture) due to the sika deer (Cervus nippon) feeding which has in turn resulted in a reduction ...
Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion chan...
