The occurrence of wind erosion could be described under following three different phases. They are: 1. Initiation of Soil Movement 2. Transportation of Soil Particles 3. Deposition of Soil Particles. Phase # 1. Initiation of Soil Movement: Soil movement is initiated by the turbulence created by strong wind currents. The movement of soil particles may be described in three distinct [...]
In this article we will discuss about how to determine and estimate erodibility factor(k) of soil. Determination of K-Factor: The first study on erodibility of materials was done by Hjulstrom. They developed a curve, called Hjulstrom's diagram which includes three sectors (erosion, transport and sedimentation) depending on water velocity and the diameter of soil particles. Analysis of the erosion sector [...]
In this article we will discuss about how to measure splash erosion. Introduction to Splash Erosion: The splash erosion is the initial phase of sediment production from the hill slopes. It has very fundamental importance in the soil erosion studies. Regarding evaluation of splash erosion, very few studies have been made so far under field condition. However, in contrast to [...]
