| Summary: | Soil erosion is globally recognised as a serious threat to the human
well being. The basic definition of the word 'Soil Erosion' commonly
means the destruction of soil by the dual action of water and wind. It is
essentially a smoothing process with soil particles being carried, rolled
or washed down by the gravitational force. Erosion induced landslide is
fundamentally a continuous process caused by two prominent means of
disturbance either geologically or accelerated that affect the geological
strata and the surface of the earth. The severity or impact on the soil strata
depends significantly on the rainfall intensity, energy and magnitude
of the rainfall erosiveness besides the degree of soil erodibility itself
which scour away, loosen and breakdown the soil particles and carry
them away. A combination of these two main factors namely rainfall
erosivity and soil erodibility can be used as a predictive tool in forecasting
erosion induced landslide. By knowing the level of rainfall erosivity and
soil erodibility impact of an area, the potential risk of erosion induced
landslide can be made known. |
