Estimation of Erosivity from Rainfall Data (2 Methods) | Soil Engineering

The rainfall erosivity is related to the kinetic energy of rainfall. The following two methods are widely used for computing the erosivity of rainfall: 1. EI30 Index Method 2. KE > 25 Index Method. 1. El30 Index Method: This method was introduced by Wischemeir (1965). It is based on the fact that, the product of kinetic energy of the storm [...]

Erosivity and Soil Erodibility | Soil Engineering

In this article we will discuss about erosivity and soil erodibility. Erosivity: It is defined as the potential ability of rain to cause the erosion. It is dependent on the physical char­acteristics of rainfall, which include raindrop size, drop size distribution, kinetic energy, terminal velocity etc. For a given soil condition, the potential of two storms can be compared, quantitatively [...]
