Groundwater vulnerability assessment using GIS-based DRASTIC method in the irrigated and coastal region of Sindh province, Pakistan

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

Qualitative Assessment of the Coastal Plain of Talesh using the Modified DRASTIC Vulnerability Method

Given the fact that the DRASTIC index is ineffective in addressing the saltwater uprising issue in coastal plains, in the present study, three factors including land use, distance to shoreline, and differences between groundwater and sea level were added to the DRASTIC index. The proposed modification to DRASTIC was validated using the measured electrical conductivity (EC) data gathered from gr...

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...

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, ...
