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:- 1. Introduction to Water Erosion Risk 2. Assessment of Water Erosion Risk 3. Factors 4. Methods. Introduction to Water Erosion Risk: The assessment of relative risk of erosion to bare soil involves consideration of slope class erodibility. Previous vegetative covers are not taken into consideration for water erosion risk analysis. Also, it is [...]
In this article we will discuss about:- 1. Types of Bund 2. Classification of Bunding System 3. Design Criteria 4. Planning 5. Construction. Types of Bund: The different types of bund used in practice are given as under: 1. Contour Bund – The bunds constructed exactly on contour or with permissible deviation from the contour, are called contour bunds. 2. [...]
