Groundwater is a precious resource of limited extend. However over exploitation has depleted groundwater availability. The increased demand for water has increased awareness towards the use of artificial recharge. The lack of effective groundwater recharge structures in a region usually brings about adverse effect on groundwater utilization. Bilha block of Bilaspur district comes under semi-critical stage of ground water development. 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. Various thematic maps including District and Block boundaries, drainage, slope, soil texture, lineaments, geology and water level depth were generated in the environment of GIS. Satellite image IRS P6 LISS III, was classified using supervised classification method to generated Landuse map of the area. The total geographical area of the district is 554151 ha in which 42.65% (236210.5 ha) is available for agriculture. The geology map has been also be generated there are find total five formation. The upper, middle and lower reaches of drainage lines were considered for different sizes of check dam. Finally 179 locations were identified for check dams, whereas 147 locations were identified for percolation tanks in Bilaspur district
Groundwater management requires a systematic approach since it is crucial to the long-term viability of livelihoods and regional economies all over the world. There is insufficient groundwater management and difficulties in storage plans as a result of increased population, fast urbanisation, and climate change, as well as unpredictability in rainfall frequency and intensity. Groundwater exploration using remote sensing (RS) data and geographic information system (GIS) has become a breakthrough in groundwater research, assisting in the assessment, monitoring, and conservation of groundwater resources. The study region is the Mand catchment of the Mahanadi basin, covering 5332.07 km2 and is located between 21°42′15.525″N and 23°4′19.746″N latitude and 82°50′54.503″E and 83°36′1.295″E longitude in Chhattisgarh, India. The research comprises the generation of thematic maps, delineation of groundwater potential zones and the recommendation of structures for efficiently and successfully recharging groundwater utilising RS and GIS. Groundwater Potential Zones (GPZs) were identified with nine thematic layers using RS, GIS, and the Multi-Criteria Decision Analysis (MCDA) method. Satty's Analytic Hierarchy Process (AHP) was used to rank the nine parameters that were chosen. The generated GPZs map indicated regions with very low, low to medium, medium to high, and very high groundwater potential encompassing 962.44 km2, 2019.92 km2, 969.19 km2, and 1380.42 km2 of the study region, respectively. The GPZs map was found to be very accurate when compared with the groundwater fluctuation map, and it is used to manage groundwater resources in the Mand catchment. The runoff of the study area can be accommodated by the computing subsurface storage capacity, which will raise groundwater levels in the low and low to medium GPZs. According to the study results, various groundwater recharge structures such as farm ponds, check dams and percolation tanks were suggested in appropriate locations of the Mand catchment to boost groundwater conditions and meet the shortage of water resources in agriculture and domestic use. This study demonstrates that the integration of GIS can provide an efficient and effective platform for convergent analysis of various data sets for groundwater management and planning.
