In gully control the structural measures protect the soil against erosion and also help to conserve the rainwater. The earth plugs and check dams form water storage in the gully which can be used as per need, later on. Also, due to obstruction on moving runoff, the soil scouring through gully section gets controlled. Various design aspects of check dams [...]
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 [...]
