DRASTIC Index GIS-Based Vulnerability Map for the Entre-os-Rios Thermal Aquifer

نویسندگان

چکیده

The sulphurous mineral waters of ‘Entre-os-Rios’, which is sited in NW Portugal, are famous for their long history as thermal baths dating back at least to the mid-sixteenth century. Because singularity its water composition, especially highest sulphur content, ‘Entre-os-Rios’ one most important Portugal. Despite these having a protection perimeter buffer zone avoid contamination, there potentially damaging installations (e.g., fuel station) closed that, according existing law, not permitted within perimeters, defeats purpose delineation. A vulnerability map was created using geographic information system (GIS) tools based on multi-criteria analysis, combining thematic maps and parameters DRASTIC index, evaluating risk contamination area. results showed that perimeter, low pollution. alluvium-covered terrain vulnerable moderate but it far from catchment point. Areas minimal corresponded locations where granitic massif had been significantly weathered. enables collection better definition local resource structures planning, namely, restricted areas emplacement some activities should be allowed agriculture prospection), given influence confined aquifer.

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, ...
