GENERAL KNOWLEDGE

Detailed explanation-1: -USLE erosivity combines the energy of the rainfall and the maximum continuous 30-min intensity in the event. Energy of rainfall is estimated as a function of the storm intensity through the rainfall event. The USLE erosivity has been used effectively for conservation planning purposes for more than 5 decades.

Detailed explanation-2: -Rainfall erosivity is the kinetic energy of raindrop’s impact and the rate of associated runoff. The R-factor is a multi-annual average index that measures rainfall’s kinetic energy and intensity to describe the effect of rainfall on sheet and rill erosion.

Detailed explanation-3: -Erosivity is the term used to describe the potential of raindrop impact, runoff from snowmelt, or water applied with an irrigation system rainstorm to detach and erode soil.

Detailed explanation-4: -Erosion started at a low intensity and increased substantially as a result of small increment in rainfall intensity. Soil erosion is influenced by the formation of surface crust in this arid region. Soil erosion during the wet and very wet runs increased as the antecedent soil moisture content increased.
