Accomplishment and subjectivity of GIS-based DRASTIC groundwater vulnerability assessment method: a review

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...

GIS and Statistical Groundwater Vulnerability Modeling

ArcGIS Desktop* and ArcGIS Workstation* were used to extract statistically significant information from various geospatial data sets for input into a statistical model of groundwater vulnerability. The product of this effort was a probability map that identified areas of vulnerability to groundwater-quality degradation. This information is of interest to a variety of water professionals because...
