The Universal Soil Loss Equation was developed to predict the annual soil loss from field-size small areas. This equation does not compute the sediment yield from the watershed, directly. To compute the sediment yield by use of USLE, the computed soil loss using USLE is multiplied with the delivery ratio of watershed. Since, USLE predicts the annual soil loss, therefore, [...]
Regarding soil conservation the term 'cover crops' is almost symonynous to the 'green manure' crops. The cover crops are primarily grown as a measure to control or reduce the soil erosion. These are grown either during off-season or when ground protection is required. In United States these are grown at winter annuals, and after harvesting they are ploughed for green [...]
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 [...]
