Soil–Water Conservation, Erosion and Landslide

Soil Erosion and Conservation

Landslide erosion coupled to tectonics and river incision

The steep topography of mountain landscapes arises from interactions among tectonic rock uplift, valley incision and landslide erosion on hillslopes. Hillslopes in rapidly uplifting landscapes are thought to respond to river incision into bedrock by steepening to a maximum stable or ‘threshold’ angle1–3. Landslide erosion rates are predicted to increase nonlinearly as hillslope angles approach ...

soil erosion; challenges, costs and its conservation benefits

in future, soil erosion will be a great challenge for biosphere. if the soils today are notprotected carefully hunger crises all over the world will be widespread. the present article endeavorsto survey soil erosion process and approaches to prevent it. furthermore the article tries to review therelation between soil character and soil production capability shedding light on the effect of erosi...

Environmental and economic costs of soil erosion and conservation benefits.

Soil erosion is a major environmental threat to the sustainability and productive capacity of agriculture. During the last 40 years, nearly one-third of the world's arable land has been lost by erosion and continues to be lost at a rate of more than 10 million hectares per year. With the addition of a quarter of a million people each day, the world population's food demand is increasing at a ti...

GIS and Multicriteria Analysis to Evaluate and Map Erosion and Landslide Hazards

A rich georeferenced data base on a flood event in the north west of Italy and the knowledge of experts from the different involved disciplines have been used as the basis for the application of an outranking method, ELECTRE III, oriented to the structuring and validation of consistent multicriteria models for hazard evaluation. The models were developed with the aim of explaining the multidime...
