Gabion structures are made with boulders packed closely in wire mesh cages. They are constructed in gullies for retention of debris and soil accumulation without ponding. These structures encourage good plant cover not only along the bank but also in the bed of the stream due to increased moisture regime. The design of regular Gabion Structure has been modified to facilitate storage of rainwater in addition to reducing flow velocity and controlling soil erosion in the middle reaches of the drainage line in watersheds. This design was successfully field tested in Laxmipur watershed falling in Karimnagar district of Telangana state. The structure was designed to handle runoff from 40 ha catchment. The design and cost estimate details and specific modifications made in design etc., are given in this paper. The width and depth of gully at the site of construction were 10 and 1.5 m, respectively. The height of structure was kept at 0.75 m. The cost of the structure was about Rs. 55,000/- against the estimated cost of Rs. 2 lakh for constructing the pacca/masonry check dam at the same site. The constructed water harvesting Gabion structure is able to harvest 10 lakh litres of rain water (with two fillings). The modified low cost water harvesting gabion structure is serving as a low cost alternative to expensive masonry check dams.
