Watershed Development

Product/Process

Process to augment under- ground water resource and check soil erosion.

Application/Use

Sustainable water supply in dug wells/hand pumps; augment drinking water supply & irrigation potential, check soil erosion, reclamation of wastelands.

Salient Features of Process/Technology

The concept of 'hill to valley' is adopted to arrest rainwater at selected points in the catchment area. In the hilly terrain, continuous as well as discontinuous trenches are made while in the valley, continuous trenches, boulder check dams or ponds are constructed on secondary/tertiary drains. These water storage structures recharge the ground water and raise the water table level. This also checks soil erosion. Micro watersheds can be planned in semi-arid zones. It takes 3 yr for marked impact.
