To provide more reasonable references for remedying underground water, fuel leak was simulated by establishing an experimental model of a porous-aquifer sand tank with the same size as that of the actual tank and by monitoring the underground water. In the tank, traditional gasoline and ethyl alcohol gasoline were poured. This study was conducted to achieve better understanding of the migration...
Water distribution systems are complex interconnected networks that require extensive planning and maintenance to ensure that the drinking water is delivered to the consumers. Lack of adequate water supply in urban areas is due to aging water distribution systems and inadequate maintenance of this critical infrastructure (Bhave 2003). The reliability of such deteriorating systems is continually...
Oman is located in the tropic of Cancer with extremely hot temperatures ranging between 15 ̊C -25 ̊C in winter and 30 48 ̊C in the summer with low rainfall. Most of the water source is desalinated seawater. Recycling of sewage effluent is a common practice used for farming, public parks and industry. The dried sludge product is used as fertilizer. The highly concentrated sludge with heavy metals i...
It is a basic process, distinguishing of water based on quantity and quality properties and condition of it reach for consuming optimum. It has been to descent processes the level of underground water according to simple hydrograph of Shiraz plain in statistical period of 1993-2011 that totally the level of underground water has been decreasing about 5.98 meters. It has been decreased the quali...
underground dams have recently been considered as hydrological structures for the development of water resources, especially in the dry regions of iran. in this investigation along with the basic studies and the aquifer flow modeling, the probable hydrogeological effects of an underground dam are investigated. the proposed place for the ganjeh underground dam is chehel-khaneh aquifer located in...
extended abstract introduction water resources management in arid and semi-arid areas is very important to provide of water for stakeholders. in recent decades, construction of underground dams have been considered, because of its advantages. these dams have many advantages, e.g., unlike a surface dam, land is not submerged to store water and there is no danger of breaching due to natural or ma...
A large part of Iran is considered a semi-arid regions and water is a limiting factor for human activities in these areas. One of the ways to eliminate seasonal shortages of water is using groundwater. Underground dams can be used for storing and using underground water, which can be used to improve the management of existing water resources and increase the productivity of these resources.1 . ...
The water balance calculation and water quality are very important matters in the groundwater management. The water balance includes two parameters: input and output parameters. The input parameter is consisted from surface recharge (precipitation, irrigation return water, surfaces runoff recharge) and underground inflow (flow from adjacent aquifers). The underground inflow is an important fact...
