Abstract:
—A groundwater development program requires a large
volume of data from various sources. An integrated remote sensing,
MCDA and GIS study can provide the appropriate platform for
convergent analysis of large volumes of multidisciplinary data and
decision making for groundwater studies. Geospatial technologies
have become an important tool in water studies due to their
capability in developing spatio-temporal information and
effectiveness in spatial data analysis and prediction. The sustainable
development and management of groundwater resource needs
quantitative assessment, based on scientific principle and recent
techniques.
The analysis of PGZs can use the parameters such as drainage
density, elevation, geology, geomorphology, land use and land cover,
lineaments-dykes, rainfall, slope and soil pattern etc. and can assign
weightage by using Analytical Hierarchical Process etc.; then
weighted overlay analysis in ArcGIS will accurately find the zone for
groundwater distribution.
The overall assessment as presented in this study highlight that
mapping of groundwater potential using integrated
RS/GIS/MCDA/AHP/WLC approach could be an effective means of
characterization of groundwater potential zones as well as serving as
a useful tool and guide in groundwater exploration and development
could serve as a base line study for future water management
projects in the area. This Integrated geospatial techniques could
serve as a base line study for future water management projects in
order to ensure sustainable ground water utilization.
