gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Evaluation of surface water quality is a complex process undertakingmultiple parameters. Converting great amount of parameters into a simpler expressionand enabling easy interpretation of data are the main purposes of water quality indices.The main aim of this study is to plan effective water resources management system forKarun River by combination of CCMEWQI and Geographic Information System ...

rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Abstract The 2000 European Union Water Framework Directive (WFD) states that “Member States shall ensure the necessary protection for bodies of water identified with aim avoiding deterioration in their quality order to reduce level purification treatment required production drinking water.” However, it does not specify how evaluate or quantify this treatment. We propose a novel index (WQI) prep...
Abstract The aim of this study is to determine the Caracosh (Al-Hamdannia district) groundwater water quality index (CCME WQI). This was calculated by taking samples and putting them into a thorough physicochemical examination. For calculating WQI, following 9 parameters have been considered: pH, TDS, T. Alkalinity, hardness, Ca, Mg, Chloride, Sulphate Nitrate. WQI for these ranges from 25.19 9...
