freshwater lens on small islands may easily be overexploited or polluted due to overdrafts of fresh water by pumping which causes drawdown of the water table a rise or up-coning of the saltwater interface. present study is concerned with using a three-dimensional finite-difference numerical model to simulate the groundwater flow and transport model to predict the behavior of groundwater system ...

Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

Groundwater is one of the most vital of all common pool resources throughout the world. More than half of groundwater is used to grow crops. This research models groundwater depletion patterns within a multiagent system framework. Irrigators are modeled as agents in the multi-agent system. The irrigation strategies adopted by the agents are investigated using game theory, under several futurist...

Drinking contaminated groundwater can have serious health effects. Bacterial assessment of groundwater in Ekiti State was carried out to determine its potability and source(s) of pollutants. Consequently, 73 groundwater samples were collected for bacterial analysis and NO3 determination. At each location, depth of each well and depth to water table were measured using dipmeter. Temperature (°C)...

250 words) The increasing pressure and overexploitation of water bodies in the recent decades are negatively affecting the quality and quantity of aquifers. Its deterioration is also having many negative impacts on numerous ecosystems connected with these water bodies, as is the case of groundwater-dependent ecosystems (GDEs). Therefore, the protection of groundwater resources and ecosystems ar...

We measured denitrification, immobilization, and respiration in microcosms that simulated groundwater conditions in a riparian forest in Rhode Island. Measured rates were compared with rates of NOj" removal measured in a companion study using a groundwater monitoring well network and 10-mo injection of NOf and a bromide tracer to groundwater in the same riparian forest. Limiting factors for den...

An assessment of groundwater pollution in the area surrounding a domestic wastewater treatment plant in northern Jordan has been carried out. Groundwater in the study area is classified as alkaline earth water with increased portions of alkalis and prevailing chloride, tending to shift to alkaline water with the dominance of chloride. This trend indicates mixing between the two end members of f...
