this research was conducted in order to study the effect of climate and geology factors on groundwater sources in mahvelat plain. in order to study the groundwater quality and quantity considering groundwater resources including wells and qanats; using groundwater surface, electric conduction (ec) and the total density solution (tds), the maps of groundwater surface fluctuation and quality para...

The prediction of groundwater quality is very important for the management of water resources and environmental activities. The present study has integrated a number of methods such as Geographic Information Systems (GIS) and Artificial Intelligence (AI) methodologies to predict groundwater quality in Kerman plain (including HCO3-, concentrations and Electrical Conductivity (EC) of groundwater)...

Our main objective in the present study was to assess the spatial variation of chemical and physical water properties. Prior to the design of groundwater quality monitoring networks, it is essential to investigate the spatial structure of the groundwater quality variables. A case study is presented which used ground water quality observations from groundwater domestic wells in the Dameghan, Ira...

Groundwater is the most important source of water supply for agricultural purposes in arid and semi-arid areas. In many areas, excessive use of high quality water resources leads to reducing the available water resources and turning to the use of low quality water resources. Thus, knowing the temporal and spatial variation of groundwater quality is a necessary factor for implementation of sound...

Leachate and groundwater samples were collected from Gazipur landfill-site and its adjacent area to study the possible impact of leachate percolation on groundwater quality. Concentration of various physico-chemical parameters including heavy metal (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and microbiological parameters (total coliform (TC) and faecal coliform (FC)) were determined in groundwater and lea...

Evaluation of groundwater hydro chemical characteristics is necessary for planning and water resources management in terms of quality. In the present study, a self-organizing map (SOM) clustering technique was used to recognize the homogeneous clusters of hydro chemical parameters in water resources (including well, spring and qanat) of Kerman province; then, the quality classification of groun...

Abstract Background and purpose:In many regions especially in the north of Iran groundwater is the most important resource for drinking supply. A present study was carried out in the Tajan plain in northern Iran. The aim of this study was to evaluate the quality of groundwater. Materials and Methods:In order to constructing the groundwater quality index (GWQI) 3 main levels were composed select...

© 2007 Wiley Periodicals, Inc. Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/tqem.20130 Groundwater is an essential source of drinking water in rural India. Contamination of groundwater (resulting from human activities or from inherent aquifer material composition) reduces the supply of safe drinking water, posing a threat to public health and a challenge to ...
