In this article we will discuss about the mechanics of stream bank failure and its control. The flow of water in the stream generates shear stress on the bed and banks, both, as a result the bank gets retreated in following two ways: i. Materials get eroded directly from the bank and carried downstream by the flow. ii. When shear [...]
In this article we will discuss about the twelve methods used for controlling stream bank erosion. The methods are: 1. Stream Bank Stabilization—Gabion Method 2. Vegetated Geo-Grid Method 3. Iowa Vanes 4. Vegetative Riprap 5. Stone Riprap 6. Pilings with Wire or Geotextile Fencings 7. Dormant Post Plantings 8. Coconut Fiber Rolls Method 9. Branch Packing Method 10. Live Fascine [...]
Problem soils possess undesirable physical properties like infiltration, water holding capacity, structure, texture, hydraulic conductivity and bulk density. These soils have soluble salts like chlorides and sulphates of Ca and Mg and Na in higher concentration. This leads to improper growth and development of crops resulting in low yield of crops. The soils possessing various constraints and management strategies are [...]
