Geospatial Technology Based Groundwater Potential Zone Mapping In Parts of Noyyal Basin, Tamil Nadu, India
Authors(3) :-Karung Phaisonreng Kom, B. Gurugnanam, K. Kalaivanan Groundwater is considered as one of the most valuable hidden natural resources in the sub-surface. Generally, the rapid growth of population, urbanization and agricultural development leads to a major issue for progressively stresses of water in all over the world. Therefore, groundwater is gaining extensive attention to meet the demands. This study aims to delineate the groundwater potential zone (GWPZ) in parts of Noyyal basin, Tamil Nadu, India using remote sensing (RS) and geographical information system (GIS). Fissile hornblende-biotite gneiss, hornblende-biotite gneiss, fluvial (black cotton soil with gypsum), granite, charnockite, garnet sillimanite – graphite gneiss are the major rock types and amphibolite, fuchsite, sericite – quartzite, pyroxene granulite, patches of ultramafic rocks and calc – granulite and limestone are minor rock types in this region. Usually, the river flow is dependent both on northeast and southwest monsoons. The downstream portion of the river mostly in Coimbatore city is extensively polluted due to the direct discharge of domestic sewage and effluent from dyeing and bleaching industries. Consequently, groundwater close to the river turns into contaminated. Hence, proper management and planning of the aquifer in this region are mandatory. This planning includes preparation of groundwater prospective map to identify the groundwater potential of the study area using RS and GIS. Several thematic layers such as geology, geomorphology, drainage, drainage density, lineament, lineament density, slope, soil type, soil texture, soil depth and land use/land cover (LU/LC) were built in the GIS environment to generate the groundwater potential zonation map of the study area. Each individual thematic layer was given appropriate weight and ranking based on their contribution towards groundwater recharge and storage using spatial analyst tool in ArcGIS 10.2. In this manner, a final map i.e. groundwater potential zonation map (GWPZM) was produced by compiling all the required themes. The map indicates that the GWPZ of the study area can be classified into four categories such as very good (32 km2 of the area), good (334 km2 of the area), moderate (727 km2 of the area) and poor (331 km2 of the area). The region falling in very good groundwater potential category is auspicious for groundwater prospect. This study validates that RS and GIS provides a pathway to delineate the groundwater possible zones of the study area.
