Abstract

A study was conducted to locate appropriate places for artificial groundwater recharge structures for all the blocks of Durg district in Chhattisgarh. Various thematic maps including district boundaries, drainage, slope, soil texture, land use, lineaments, geology and water level depth were generated in the environment of GIS. These thematic maps were superimposed accordingly to identify the appropriate places for artificial groundwater recharge structures. Different structures and their size have been decided on the basis of topography and drainage pattern. The upper, middle and lower reaches of drainage line were considered for different size of check dams. The site for percolation tank has been identified for both cultivated and uncultivated land. The field survey of the study area was also carried out to find out the suitability of proposed artificial groundwater recharge structures. Results of this study indicated that only 36.8% of the area was found to be very good suitable sites, 13.2% of the area was found to be good suitable sites and about 10% area was found to be moderate suitable sites for recharge. Finally, 62 locations were identified for check dams, whereas, 31 locations were identified for percolation tanks. The sub-surface storage space was estimated to be 32.47 Mm3 on the basis of thickness of available vadose zone. The actual volume of 43.18 Mm3 of surface water required for saturating the vadose zone. It was found that sufficient volume of water required for artificial recharge is available. Availability of source water to recharge the subsurface reservoir has been found to be 882.75 Mm3 in the form of non-committed surplus runoff out of which 30 per cent (264.82 Mm3) is considered as surplus monsoon run-off which is available for artificial recharge.
