study of groundwater quality trend in any region is very important from the view of scheduling and sustainable water resources management. in the present study trend analysis conducted on groundwater quality based on information of 32 piezometeric stations located in the ardabil plain from 1993 to 2008 using the non-parametric spearman test. hydrogeochemical variables studied here are total ani...

Increasing pressure on water supply worldwide, especially in arid areas, has resulted in groundwater overexploitation and contamination, and subsequent deterioration of the groundwater quality and threats to public health. Environmental risk assessment of regional groundwater is an important tool for groundwater protection. This study presents a new approach for assessing the environmental risk...

Overexploitation of groundwater resources has caused groundwater-related problems all over the world. Effective groundwater governance is a favorable guarantee for its protection and sustainable utilization. Accurate prediction of groundwater level (GWL) or depth to groundwater (GWD) plays an important role in groundwater resource management. Due to the limitations and complexity of numerical m...

Iran is among the world’s arid and semi-arid regions and its demand for water has been increased due topopulation growth, urbanization and the development the economic sectors (industrial and agricultural).
