Modeling groundwater vulnerability to pollution using Optimized DRASTIC model

modification of drastic model to map groundwater vulnerability to pollution using nitrate measurements in agricultural areas

drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...

Assessing the groundwater vulnerability to pollution using DRASTIC and SINTACS models, case study: Evan Plain, south west of Iran

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...

Groundwater Vulnerability to Pollution in Urban Catchments

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...
