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...

India is gifted with a rich and vast diversity of natural resources and water is one of them. It plays a vital role in agriculture production. The pumping of ground water to irrigate crops consumes about 50% of the ground water resources and around 35% of the electricity generated in the country. In order to meet the growth target for power availability, its entire requirement cannot come solel...

One of the biggest challenges in managing cold water streams in the Midwest is understanding how stream temperature is controlled by the complex interactions among meteorologic processes, channel geometry, and ground water inflow. Inflow of cold ground water, shade provided by riparian vegetation, and channel width are the most important factors controlling summer stream temperatures. A simple ...

Scientists and engineers understand and communicate hydrologic concepts with the one-word or two-word form of ‘‘groundwater’’ or ‘‘ground water,’’ with care toward consistency in their usage. Both forms certainly mean the same thing. Scientists and engineers also want to improve the public’s scientific understanding of water resources to ensure their future quality and availability. Language pr...

groundwater drought denotes the condition and hazard during a prolonged meteorological drought when groundwater resources decline and become unavailable or inaccessible for human use. the aim of this study is to identify the influencial factors on groundwater drought in hamadan- bahar watershed,iran, to understand the forcing mechanisms. the standardised precipitation index (spi) has been used ...

background: radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. the presence of radon gas is common, wherever those faults are located there. radon concentration of various drinking water resources of bam villages; located near bam fault; was measured. materials and methods: this cross-sectional study was cond...

background: in the present times, arsenic poisoning contamination in the ground water has caused lots of health‑related problems in the village population residing in middle gangetic plain. in bihar, about 16 districts have been reported to be affected with arsenic poisoning. for the ground water and health assessment, simri village of buxar district was undertaken which is a flood plain region...

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). inmany of these regions, the lack of planning and the unauthorized use of resources have led to excessiveexploitation and a lower level of groundwater. the usable groundwater for the country...

Background & Aims: The presence of heavy metals in water resources is a serious threat to human health. Due to the importance of this subject, this research was carried out to determine the concentration of heavy metals in drinking water resources of central and Southern Bardsir plain and compare the results with national and international standards. Methods: The descriptive and cross-sectional...
