Abstract There are different sources of groundwater pollution among them industrial water disposal, seawater ingress, usage pesticides and fertilizers in agricultural fields, municipal residential wastewater disposal. The aim the study is to assess vulnerability terms quality using GOD method Geographical Investigation System approach for Surat its surroundings. Groundwater confinement, overlyi...

A method to predict groundwater vulnerability to pesticide contamination on a regional scale has been developed and applied to a part of the upper Rhone river valley in Western Switzerland. Ž . Stochastic application of deterministic pesticide leaching models Monte-Carlo , along with geostatistical interpolation techniques, were used to map both vulnerability levels and uncertainŽ ties. The var...

increasing growth of population leads to increase in human activities such as agriculture and industry, which these activities increasing and irregular usage of fertilizers, pesticides and insecticides result in soil and groundwater pollution. meanwhile, vulnerability assessment can play important role in the management of polluting activities. in this research a new method has been proposed fo...

This work extends the overlay and index methods for intrinsic groundwater vulnerability, that typically involve soil surface vadose zone, to (saturated) transport. The method is “hybrid” as it combines standard with a simplified process-based approach component. For latter, we make use of concept methodologies based on geomorphological analysis, employing tools are generally implemented in Geog...

During the past two decades, geographic information systems (GIS) have played a more significant role in the realm of science. This paper reviews some representative approaches about the integration of GIS and hydrological modeling. Among the different kinds of hydrological modeling this paper will mainly focus on urban flooding modeling, surface water quality modeling, and groundwater vulnerab...
