soil erosion in a given area depends on natural characteristics of the place as well as the rate of  human impact. in iran, the mediterranean precipitation regime and relatively high erosivity of rain, wide area of erodible soils/lithological formations, sparse natural vegetation in many regions and mountainous topography are main natural factors that affect soil erosion by water. accelerated s...

Soil erosion is a crucial problem in Nepal where more than 80% of the land area is mountainous and still tectonically active. Although deforestation, overgrazing and intensive agriculture, due to population pressure, have caused accelerated erosion, natural phenomena inducing erosion, such as exceptional rains, earthquakes and glacial-lake-outburst flooding in the high Himalayas are also common...

The article presents the results of research on effect sprinkling structural and aggregate composition soil its density. high quality irrigation is achieved with uniform distribution rain over area, acceptable intensity drop diameter impact force, at which plants structure are not damaged, puddles surface runoff formed. For complete absorption water into preservation low intensity, small drops ...

Erosion caused by human activities is one of the reasons for forest soil degradation worldwide, with a direct impact on stands development, including reduced productivity. Therefore, in order to establish sustainable stand management practices, it essential assess losses various forestry activities. Moreover, this phenomenon studied little stands, especially those established degraded land. In ...

Stability of Geosynthetic Lining Systems is, for a geotechnical standpoint, a complex matter. Three geomechanical questions were identified: sliding of the geosynthetic lining system on slope, pull-out strength of the geosynthetic anchorage at the top of the slope, rain erosion of the cap cover. Research programmes carried out in France on these topics, , are presented. Use of laboratory facili...

The effects of a wildfire, occurred in August 1992, on nutrient losses by water erosion have been studied. The fire affected an area of 9498 ha of Pine forest and shrub, located in Sierra Calderona (Valencia, Spain). In the burned area, six stations of erosion measurement were set up immediately after the end of the fire. The results obtained in these stations are reported. Topographical, edaph...

Foredune volume is an important factor for coastal safety and depends on the balance between erosion through wave attack and sediment input via aeolian transport. Dune erosion can be simulated with good accuracy, but predictions of aeolian sediment transport into the foredunes are still difficult to make. As part of a larger project that aims to model foredune development over decades, the goal...
