Abstract
Remote Sensing (RS) and geographic information system (GIS) are now very essential tools for efficient planning and management and handling a range of data simultaneously in a time- and cost-efficient manner for targeting of groundwater, which assists in measuring, monitoring, and conserving groundwater resources. Survey of India toposheets, LISS-III and CARTOSAT DEM satellite imageries are used to prepare various thematic layers viz., geology, slope, lineament, drainage, and geomorphology, and were transformed to raster data using feature to raster conversion tool in ArcGIS spatial analysis, then we reclassify each raster map using reclassify tools. By using weight overlay analysis, each weighted thematic layer is statistically computed to get the ground water potential zones. Then, five different groundwater potential zones were identified, namely “very good”, “good”, “moderate”, “poor”, and “very poor”. The villages under poor groundwater potential zone and the villages under very good groundwater potential zone are finding out. The above study has clearly demonstrated the capabilities of Remote Sensing and GIS in demarcation of the different groundwater potential zones in hard rock terrain.
Highlights
A day, the most important issues are faced by the society i.e. high population growth, fast urbanization and climate change along with the irregular rate and intensity of rainfall and its impact on the availability of water
The study was conducted to find out ground water potential zones in Bamamghaty Subdivion of Mayurbhanj district, Odisha by integrating various thematic maps in geographic information system (GIS) environment such as geology, geomorphology, soil texture, land use/land cover, drainage, lineament map was prepared for the study area
Delineation of groundwater potential zones in Bamanghaty subdivision of Mayurbhanj district using remote sensing and GIS techniques is found efficient to minimize the time, labour and money and thereby enables quick decision-making for sustainable water resources management
Summary
The surface water is not available throughout the year for various purposes It is essential for the proper management of both surface and groundwater resources by systematic inventory, conservation and proper planning for economic and social development. The occurrence and distribution of groundwater is depending by several factors such as lithology, geological structures, Geomorphology, Soil structure, slope, drainage pattern, drainage density, landforms, land use/land cover, climatic conditions and interrelationship between them [1] [2] [3]. The study was conducted to find out ground water potential zones in Bamamghaty Subdivion of Mayurbhanj district, Odisha by integrating various thematic maps in GIS environment such as geology, geomorphology, soil texture, land use/land cover, drainage, lineament map was prepared for the study area. The groundwater potential zones were obtained by overlaying all the thematic maps in terms of weighted overlay methods
