Factors Affecting Soil Erosion spindigo.com. Factors increasing mass movement include erosion or excavation undermining the foot of a slope, weight loads of buildings or embankments, and loss of stabilising roots through removal of vegetation. Vegetation removal may also increase soil water levels and soil water pressure, reducing the cohesive strength of the soil. In clay soils with high shrink-swell capacity water enters the soil, Soil erosion is a very complicated problem to solve, because there are so many factors, which affect the rate of erosion.

Among Universal Soil Erosion Equation (USLE) factors (R, K, L, S and P), Soil Erodibility Factor (K) is one of the most important and key factors which determines soil particles resistance to be de- tachment by water erosion (rainfall and/or runoff) forces. Magnitude and the impacts of soil erosion on productivity depend on soil profile and horizonation, terrain, soil management, and climate characteristics. There are so many factors and processes

The rate and magnitude of soil erosion by water is controlled by the following factors: Rainfall Intensity and Runoff Both rainfall and runoff factors must be considered in assessing a water erosion problem.
