An Approach towards Groundwater Mapping Using Geographic Information System (original) (raw)

2014

Abstract

Groundwater is attracting an ever increasing interest due to scarcity of good quality subsurface water, and growing need of water for domestic, agricultural and industrial uses. It has become crucial not only to target groundwater potential zones, but also to monitor and conserve this important resource. In this project, an attempt has been made to study the groundwater profile and to determine its suitability for human consumption (as per IS 10500: 2009) using the various tools of Geographic Information System (GIS).A study area has been selected under Bangalore East Taluk, spanning over 100 km2, roughly in the shape of a quadrilateral having coordinates (13o14’58.95”N, 77o40’0.06”E), (13o5’13.12” N, 77o46’53.54”E), (12o58’41.56” N, 77o46’47.62”E), (12o58’56.59”N, 77o40’0.38”E). Around 160 samples of groundwater have been collected from borewells and open wells within the study area, and they have been tested for parameters such as Total Hardness, Total Alkalinity, pH, Total Dissol...
