Identification of artificial groundwater recharging zone using a GIS-based fuzzy logic approach: a case study in a coal mine area of the Damodar Valley, India

Abstract

The West Bokaro coalfield is a richest coalmining belt in the Damodar Valley, India. The extensive mining of the area has resulted in disruption of the groundwater availability in terms of both quantity and quality. This has led to a drinking water crisis, especially during the pre-monsoon period in the West Bokaro coalfield area. The characterization of the hydrogeological system and the artificial recharging of the aquifers might help to better manage the problem of the groundwater-level depletion. For this purpose, seven important hydrogeological factors (water depth, slope, drainage, soil, infiltration, lithology, and landuse) have been considered to define the most suitable locations for artificial groundwater recharging in the mining area. Different thematic maps were prepared from existing maps and data sets, remote-sensing images, and field investigations for identification of the most suitable locations for artificial recharge. Thematic layers for these parameters were prepared, classified, weighted, and integrated into a geographic information system (GIS) environment by means of fuzzy logic. The results of the study indicate that about 29 and 31% of the area are very suitable and suitable for recharging purposes in the West Bokaro coalfield. However, the rest of the area is moderate to unsuitable for recharging due to the ongoing mining and related activities in the study area. The groundwater recharging map of the study area was validated with measured electrical conductivity (EC) values in the groundwater, and it indicated that validation can be accepted for the identification of groundwater recharging sites. These findings are providing useful information for the proper planning and sustainable management of the groundwater resources in the study area.

Role of Integrated Approaches in Water Resources Management: Antofagasta Region, Chile

“…The slope is an important parameter in hydrology, and it has its own significance in affecting the run-off, movement of surface water and potential infiltration [26]. In the case of groundwater resources management, slope plays a significant role in the movement of water and permitting the infiltration of water into the aquifer system [27,28]. The slope can be calculated in percent (0-100%) or in degree from horizontal (0-90 • ), and the velocity of water directly associated with the angle of slope and depth.…”

Data of remote sensing and GIS - to demarcate the potential sector of groundwater in Debre Berhan, Amhara region, Ethiopia

“…The very high lineament density was obtained in the central and north western part. Different methodologies were used for the purpose of mapping and locating the groundwater potential sectors [7], [8]. With these data, the weights of the individual thematic layer and ranking were fixed and added to the layers depending on their groundwater holding capacity using the IDW techniques.…”
