*10.2.2.4 Steam augmentation*

The most important source of ground water reservoir is leakage that occurs from natural streams or rivers. When the total available water supply in the stream/river exceeds the rate of infiltration, the excess is lost as runoff. The infiltration can be increased by installing check bunds where runoff water can be stopped when the total available water exceeds the infiltration range.

To recharge the stored water in short span of time, there must be check dam with sufficient thickness of porous bed or weathered formation. The Height of the structure should be less than 2 m and the stored water in the structures are restrained to stream course. Series of check dams are constructed at various places to control the maximum runoff.
