groundwater makes up an important part of global freshwater resources, though it is often threatened by overuse of natural resources along with abundant production of wastes in modern society. this study aims to investigate the removal of three heavy metals including nickel, cadmium, and lead from groundwater via electrocoagulation, a suitable method for treatment of water-soluble compounds, de...
برداشت های ژئوالکتریک یا مقاومت ویژه در منطقه خرمالو، واقع در استان گلستان، به منظور تعیین گسترش جانبی و عمقی سازندهای آبدار اجرا شده است. پارامترهای کیفی آب مانند tds و ec نیز از چاه های آب موجود در منطقه مذکور تعیین شده اند. هدف از این بررسی های مقاومت ویژه در این پایان نامه، تشخیص آبخوان های زیرزمینی منطقه و نیز به دست آوردن رابطه ای (خطی) بین پارامترهای ژئوالکتریکی و هیدروژئولوژیکی در منطقه...
Water pollution is an increasing global issue that societies are facing and threating human health, ecosystem functions agriculture production. The distinguished features of artificial intelligence (AI) based modeling can deliver a deep insight pertaining to rising water quality concerns. current study investigates the predictive performance gene expression programming (GEP), neural network (AN...

One of the important purposes of hydrology is to ensure water supply in accordance with the quality criteria for agricultural, industrial, and drinking water uses. The groundwater is the main source of water supply in arid and semi-arid regions. This study was conducted to evaluate factors regulating groundwater quality in Rafsanjan plain. A total of 1040 groundwater samples randomly were colle...
background: the aim of this study was to evaluate the physical and chemical quality of groundwater in the villages of qom province during summer 2014, and to compare the results with iran’s standard no. 1053. methods: this research is a descriptive sectional study. during the investigation, one step sampling with the necessary repetitions (if necessary) was performed of each well for evaluation...
Modeling surface water quality using soft computing techniques is essential for the effective management of scarce resources and environmental protection. The development accurate predictive models with significant input parameters inconsistent datasets still a challenge. Therefore, further research needed to improve performance models. This study presents methodology dataset pre-processing opt...
Salinity is a classic problem in water quality management since it directly associated with low indices. Debate continues about selecting the best model for forecasting, remains major challenge and causes much uncertainty. Accordingly, identifying optimal modelling that can capture salinity behaviour becoming common trend recent research. This study applies novel combined techniques, including ...
