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...
متن کاملFinding the Potential of Groundwater Contamination in Baghmalek Pain in GIS Condition through DRASTIC Model
Ground water is regarded as an important source of sweet water because it has less pollution potential and it has high reserve capacity compared with surface water. Therefore, it I necessary to prevent pollution from ground water, considering management of ground water resources in line with quantitative management of water resources. In this research the potential vulnerability of ground water...
متن کاملOptimization of DRASTIC method by artificial neural network, nitrate vulnerability index, and composite DRASTIC models to assess groundwater vulnerability for unconfined aquifer of Shiraz Plain, Iran
BACKGROUND Extensive human activities and unplanned land uses have put groundwater resources of Shiraz plain at a high risk of nitrate pollution, causing several environmental and human health issues. To address these issues, water resources managers utilize groundwater vulnerability assessment and determination of protection. This study aimed to prepare the vulnerability maps of Shiraz aquifer...
متن کاملVulnerability of Recently Recharged Groundwater in Principle Aquifers of the United States To Nitrate Contamination
Recently recharged water (defined here as <60 years old) is generally the most vulnerable part of a groundwater resource to nonpoint-source nitrate contamination. Understanding at the appropriate scale the interactions of natural and anthropogenic controlling factors that influence nitrate occurrence in recently recharged groundwater is critical to support best management and policy decisions t...
