Global climate change poses challenges to areas such as low-lying coastal zones, where sea level rise (SLR) and storm-surge overwash events can have long-term effects on vegetation and on soil and groundwater salinities, posing risks of habitat loss critical to OPEN ACCESS J. Mar. Sci. Eng. 2015, 3 1150 native species. An early warning system is urgently needed to predict and prepare for the co...

For the frangible ecological environment, it is very important to reasonably develop and utilize groundwater resources in Northwest China. Shallow groundwater level is an essential factor related to the eco-environmental problems such as oasis degeneration and land salinification. The lack of groundwater dynamic data is a critical concern for water resources management in the arid region. This ...

This paper presents the analytical solution of groundwater response to tidal fluctuation in a coastal multilayer aquifer system consisting of a leaky confined aquifer, a semipermeable layer, and an unconfined aquifer. The semipermeable layer, or the roof of the leaky confined aquifer, extends under the sea. Comparisons are made with solutions derived previously, which considered only a single a...

A 200m(2) pilot-scale field test successfully demonstrated the use of nanoscale zero-valent iron (NZVI) for effective remediation of groundwater contaminated with chlorinated organic compounds in Taiwan within six months. Both commercially available and on-site synthesized NZVI were used. A well-defined monitoring program allowing to collect three-dimensional spatial data from 13 nested multi-l...

Groundwater depletion is becoming a serious policy concern in many developing countries but little is known about the costs of groundwater depletion. I use annual deviations of depth to groundwater from 1999 to 2003 from the 1985-1995 decadal means for Indian districts, to investigate how production and sown area respond to groundwater fluctuations. I find that a 1 meter decline in groundwater ...

The changes in human population often correspond with change in land use, including expansion of urban areas, agriculture and increasing industrialization, which necessitate increasing the available amount of drinking water. As the surface water sources are under the pressure of pollution, it has become necessary to use groundwater at an increasing rate. Groundwater recharge can be abundant in ...

The study of the groundwater resources and their properties are very important due to the vast desert areas and arid conditions. Given the current situation in Iran, the water supply is one of the most important territorial and environmental problems. In this study, groundwater resources were surveyed and mapped in Yazd Province and their properties were modeled to determine their effectiveness...

[1] A viscoelastic model is developed to simulate the groundwater level changes in the Cho-Shui River alluvial fan in Taiwan after the Chi-Chi earthquake. An analytical solution is derived with the assumption that no leakage occurred in confined aquifers during the coseismic period. The solution is used to analyze the data collected from a high-density network of hydrologic monitoring wells in ...
