Delineating groundwater prospect zones in a region with extreme climatic conditions using GIS and remote sensing techniques: A case study from central India

Abstract

Sustainable groundwater management of an extreme climatic region is very important from both social and economic point of view. This study attempts to delineate the groundwater potential zones of Sonepur district, Odisha, which falls under an extreme climatic region, using remote sensing, geographical information system and Saaty's analytical hierarchy process (AHP). Different ancillary data, multiple data sets obtained from LANDSAT 8 OLI and ASTER Level-1T were used in conjunction with Cartosat-1 imagery to study the detailed physical attributes of the study area and to prepare the groundwater prospect map using a weighted overlay method in ArcGIS 10.4 software. The AHP technique was used for determining the weights of each layer. From the groundwater prospect map, it was found that 52% of the area belongs to the moderate groundwater prospect zone followed by good to very good, very good to excellent (32%) and poor (16%) groundwater prospect zones. Statistical analysis of the number of existing wells in each of these water potential zones and their water level was used to verify the accuracy of the water potentiality estimated in this study. The groundwater potentiality map prepared as a part of this study would serve as an important tool for identifying suitable zones for rainwater harvesting and also for managing groundwater abstraction for a safe and sustainable water supply.(0123456789().,-v ol.:V)( 01234567 89().,-vol.:V)

Evaluation of Water Quality Parameters in Marshes Zone Southern of Iraq Based on Remote Sensing and GIS Techniques

“…The integrated model with the spatial capabilities of GIS together with spatial and temporal capacities of remote sensing can provide a powerful tool for management and assessment of the surface water quality problems (Ammenberg et al 2002;Azab 2012). Landsat satellite images and GIS are used to map, monitor, assess and change detection of wetland dynamics of Chennai coast in India during three periods from 1988 to 1996, 1996 to 2006 and 2006 to 2016 based on a supervised classification method (Jacintha et al 2019;Roy et al 2019), geographic information system, analytical hierarchy process and remote sensing techniques such as Aster level-1 T and Landsat 8 Oil used for sustainable groundwater management by delineate the groundwater zones in area of central India with extreme climate conditions. Developed OC-2 and Morel-3 algorithms and integrated with the remote sensing data as Landsat-8 images to estimate the concentrations of Chlorophyll-a, Kd(490) and SST in the northwest of Persian gulf during four seasons of 2014 (Dehmordi et al 2018).…”

AHP and GIS-based Delineation of Groundwater Potential of Papum Pare District of Arunachal Pradesh, India

“…The geomorphic landforms are of paramount importance in the evaluation of the groundwater potential (Roy et al 2019) due to diverse lithology and undulating structures created by long periods of surface processing (Rejith et al 2019). On the other hand, the geological characteristics reflect the aquifer status and thereby the groundwater storage (Çelik 2019).…”

Delineation of Groundwater Potential Zones in Koyna River Watershed, Maharashtra using Remote Sensing and GIS

“…LULC is a significant indicator of human impact on groundwater resources. Groundwater storage and outflow, as well as infiltration, are influenced by land use patterns [5]. Forest land, nonagricultural land, and cultivable land are the three basic categories of land use.…”
