Rain Water Harvesting in Rural areas Through Gabion Structure - Suhas Akiwate - 07-24-2014

This is a kind of check dam commonly constructed across small streams to conserve stream flows with practically no submergence beyond stream course.

A small bund across the stream is made by putting locally available boulders in a mesh of steel wires and anchored to the stream banks.

The height of such structures is around 0.5 m and is normally used in the streams with width of less than 10 m.

The excess water over flows this structure storing some water to serve as source of recharge. The silt content of stream water in due course is deposited in the interstices of the boulders in due course and with growth of vegetation, the bund becomes quite impermeable and helps in retaining surface water run off for sufficient time after rains to recharge the ground water body.
