Identification of Appropriate Location for Artificial Groundwater Recharging using Geospatial Technique in Bilaspur District

Abstract

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

Implementation of the Ahp Method to Determine the Priority of Recharge Areas in the Semarang City

“…If this happens for a long period, it can disrupt the hydrological cycle system which results in decreased quality and quantity of groundwater, flood, erosion and landslides and seawater intrusion. Several studies have been conducted to maintain groundwater supplies, including by building wells and infiltration trenches [1,2], and groundwater recharge areas [3,4,5,6].…”

“…The methods of the selection can be grouped into three. The first method is by using analysis on geospatial data [3,5,7,19,20]. The second one is by using Analytical Hierarchy Process (AHP) [2,4,8].…”

“…Through reference studies that have been carried out by the authors, these researchers used a variety of variables in determining which areas are suitable for use as groundwater recharge areas. Deeksha [12] uses variables taken from GIS data such as geological maps, drainage maps, land use maps, soil texture maps, and area maps. Other researchers used data from evaporation, cost benefit, sediment, hydrology (rainfall frequency) [13].…”
