Groundwater Vulnerability Mapping in Faisalabad District Using GIS Based Drastic Model

Groundwater vulnerability to pollution mapping of Ranchi district using GIS

Groundwater pollution due to anthropogenic activities is one of the major environmental problems in urban and industrial areas. The present study demonstrates the integrated approach with GIS and DRASTIC model to derive a groundwater vulnerability to pollution map. The model considers the seven hydrogeological factors [Depth to water table (D), net recharge (R), aquifer media (A), soil media (S...

GIS-based DRASTIC method for groundwater vulnerability assessment: a review

A GIS based DRASTIC model for assessing groundwater vulnerability in shallow aquifer in Aligarh, India

Surface water quality can be determined by hydrological responses that vary geographically. The sub-surface hydrologic environment, however, has a primary influence on groundwater movement and hence pollutant migration to the subsurface water. Maps of aquifer vulnerability to pollution are becoming more in demand because on the one hand groundwater represents the main source of drinking water, ...

groundwater vulnerability assessment using gis-based drastic model in the bazargan and poldasht plains

bazargan and poldasht plains are located in the north of west azarbaijan, northwest of iran. in this area, groundwater supplies main water demands. aim of this research is assessment of aquifer vulnerability for contamination potential on the basis of hydrogeological conditions of the study area. for this purpose the combined use of the drastic and geographical information system (gis) demonstr...

Aquifer Vulnerability Assessment for Sustainable Groundwater Management Using DRASTIC

Groundwater management and protection has been facilitated by computational modeling of aquifer vulnerability and monitoring aquifers using groundwater sampling. The DRASTIC (Depth to water, Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone media, and hydraulic Conductivity) model, an overlay and index GIS model, has been used for groundwater quality assessment because it r...
