Abstract:
Groundwater is an important resource that contributes
significantly to domestic and industrial purposes. The water demand is
increasing due to the depletion of groundwater. Uncontrolled drilling of wells,
construction of agricultural wells, and abstraction cause various water-related
problems. However, groundwater availability is depleted considerably due to
overexploitation, which has led to the collapse of land in some places. The
combination of remote sensing (RS) and geographic information systems
(GIS) to explore groundwater resources is a breakthrough in the field of
groundwater research. It helps in the monitoring, conservation, and
assessment of groundwater resources. The main objective of this research is
to identify the groundwater potential of the study area through the technique
of identifying groundwater potential zones using remote sensing and a
Geographic Information System. Satellite data and other secondary data
sources were used to obtain the slope, geology, geomorphic units, lineament
density, and drainage density, which are considered key parameters that can
provide accurate information in identifying groundwater potential zones.
Identification and mapping of groundwater potential analysis were done using
the weighted overlay method in ArcGIS. The study identified water potential
zones of poor (7%), moderate (36%), good (40%), and excellent (17%)
groundwater potential zones in the Rambukkana area. Additionally,
groundwater potential zones based on Village Officer (GN) divisions of the
region are analyzed to add strength to the study.
