Abstract
Groundwater is a precious resource of limited extend. However over exploitation has depleted groundwater availability. The increased demand of water has increased awareness towards the use of artificial recharge. The relentless increase in population and the resulting spurt in the demand of water requirement, carefully planning and management of this limited water resource is urgently needed. The lack of effective groundwater recharge structures in a region usually bring about adverse effect on groundwater utilization. Looking to the need of groundwater recharge plan for this district a study on groundwater recharge planning was carried out in the Department of Soil and Water Engineering, Faculty of Agricultural Engineering, IGKV, Raipur. Proper groundwater recharging may drastically change the scenario of groundwater availability of these areas. It needs appropriate groundwater recharge locations, which can be prepared by using satellite data and GIS. The present study was aimed to identify appropriate location for artificial recharge structures in this district.
The use of thematic map it has to be included drainage, slope, soil texture, lineaments, geology and water level depth to identify appropriate location of the groundwater structures were generated in the environment of GIS. Supervised classification method to generated Land use/Land cover map of the area. Check dam and percolation tank numbers are found to be 47 and 167 respectively. Raipur district having 2898 km2 area workouts to be 1199.29 Mm3 and 30 per cent of the total runoff i.e. 366.96 Mm3 is considered as surplus monsoon runoff available for artificial recharge. The total length of stream was found to be 3253.08 km. Drainage density of the area is found to be 1.12 km/km2 which was indicate low runoff potential of the study area. The geology formation is Dolomite, Chandi Sandstone, Shale, Chandi Limestone and Limestone. Nearly 12.54% (i.e.36347.92 ha.) of the total area is arable land. The vadose zone of 231.32 Mm3 is available for artificial recharge water required for recharge in district was 231.32 Mm3.
Artificial groundwater recharge can be an interesting option in an integrated strategy to optimize total water resource management. Remote Sensing, GIS and GPS technology is used to provides the real time and accurate information.
