Groundwater over-abstraction may cause land subsidence (LS), and the LS mapping suffers subjectivity associated with expert judgment. The paper seeks to reduce hazard, vulnerability, risk by formulating an inclusive multiple modeling (IMM), which combines two common approaches of multi-criteria decision-making (MCDM) at Level 1 artificial intelligence (AI) 2. Fuzzy catastrophe scheme (FCS) is u...

چکیده این تحقیق با هدف پهنه­بندی آسیب­پذیری آبخوان مرند با استفاده از روش­های drastic، avi و مقایسه پهنه بندی در سه روش مذکور انجام شده است. روش drastic از ترکیب هفت مشخصه هیدروژئولوژیک قابل اندازه­گیری و مؤثر در انتقال آلودگی به آب­های زیرزمینی تشکیل شده است. روش  aviنیز دارای دو مشخصه است. نتایج حاصل از روش drastic تقریباً کامل­ترین شاخص برای ارزیابی میزان آسیب­پذیری آب­های زیرزمینی است که مح...

Abstract Over the last three to four decades, several methods for assessing groundwater vulnerability anthropogenic pollution have been developed. Researchers and policymakers widely used these preventing through knowledge about particularly vulnerable areas. This systematic review presents different significant of aquifers protection resource. Previous studies mentioned that formulating a sing...

introduction drastic model is an index and overlapping model that has been designed for producing vulnerability scores for different points by combining several thematic layers. overlapping distinguished methods are themost applicable methods for evaluatingvulnerability of aquifers because they are cheap, they can directly reach a defined goal, the used data in the methods are accessible or can...

Contamination of groundwater has become a major concern in recent years. Since testing of water quality of all domestic and irrigation wells within large watersheds is not economically feasible, one frequently used monitoring strategy is to develop contamination potential maps of groundwater, and then prioritize those wells located in the potentially highly contaminated areas for testing of con...

Abstract Groundwater resources in the south Darb El Arbaein are currently threatened by agricultural impact and rock water interaction associated with over exploitation. Planning of Nubian sandstone aquifer is required, especially this new invest area. It implemented GIS to establish vulnerability areas evaluate protocol plans for hydrogeological parameters soil. The TDS concentration ranged fr...

Abstract This study performed a correlation analysis between groundwater quality parameters with organic and inorganic pollutants using the area under curve (AUC) of receiver operating characteristics (ROC) map in Kano Metropolis, North-western Nigeria. The aim is to present spatial relationship existing vulnerability condition resources view developing risk map. Eight water (Ca, Al, Cl, NO3, T...

Water quality has an high impact on human health. Chemical mixtures deployed in the environment can lead to multilevel contamination, going from groundwater through surface water, crops, vegetables, livestocks and, finally, humans. Groundwater can be contaminated by the percolation of chemical compounds due to various management errors, which can be mainly re-conducted to vulnerability of the g...
