In arid and semiarid regions, water demands of different sectors are related to groundwater resources. Therefore, the assessment of its changes is very important to achieve sustainable development and optimal management of aquifers in the future periods. The aim of this study was to evaluate the effects of climate change on Islamabad aquifer. For this purpose, the output of general circulation ...
Abstract: Groundwater shortage has become a very serious problem in Sanjiang Plain. More and more so-called “funnels” and “hanging pumps” situations occurred due to water shortages. The overall trend of groundwater level has decreased continually over the years. In this study, the Chuang Ye Farm in Jian San Jiang Department was taken as an example to develop a non-stable time series random mode...
It is over two decades that groundwater flow models are routinely implemented for better management of groundwater resources.Modeling groundwater flow with the help of the ground water modeling system (GMS) in the Damghan plain aquifer in northern Iran,which experiences declining levels and numerous environmental hazards, has demonstrated that, (a) in the worst case scenario theaquifer will fac...
Estimating the volume of groundwater contribution to runoff within a watershed is one of the most important subjects in water resources management and hydrology. In this paper, groundwater contribution to total runoff as a base flow index was estimated using hydrograph separation in six stream gauging stations in southwest of Iran. The major objective of this research is to distinguish the most...
Background & Aims of the Study: Heavy metals are one of the most important environmental pollutants which agricultural and industrial activities and urban development increased their entry rate to the underground resources. This study aimed to investigate the concentration of chromium, nickel and manganese in groundwater resources in Asadabad plain....
Groundwater is a precious and limited resource [...]
