In this study, we examined possible impacts of the Yangtze River Three Gorges Dam (TGD), the world largest hydroelectric construction, on the adjacent marine ecosystem of the East China Sea (ECS) during its initial water storage period. The TGD filled the first one-third of its storage capacity of 39 billion m3 in 10 days in June 2003, causing an abrupt reduction in the river flow into the ECS....
The effects of changes in climate predicted for 2100—reduction recharge, increase water demand and sea-level rise—on groundwater volume saltwater intrusion have been quantified the Maltese Islands, an archipelago located at center Mediterranean Sea. A three-dimensional density dependent heterogeneous model, working transient conditions, was developed based on morphological geological informatio...
Abstract The currents and water mass properties at the Pacific entrance of Indonesian seas are studied using measurements three subsurface moorings deployed between Talaud Halmahera Islands. moored current meter data show northeastward mean toward Ocean in upper 400 m during nearly 2-yr mooring period, with maximum velocity northern part channel. transport 60- 300-m depths is estimated to be 10...
Saltwater intrusion widely occurs in coastal areas. Therefore, dissolved salts are the most common contaminants in freshwater in coastal aquifers and this contamination arises from saltwater invasion, caused primarily by human activities due to heavy urbanization. For investigation of the methods of increasing storage of fresh ground water and prevention of seawater encroachment, predicting the...
The case study of the brackish spring of "Almyros of Heraklio" in Crete (Greece) and its vast carbonate coastal aquifer is presented, showing the consequence of preferential flows of continental fresh water and saline sea water in karst galleries in a coastal area. Flow heterogeneity generates unexpected upconing in boreholes, and permits the spring of Almyros not to be directly connected with ...

Variability of groundwater quality parameters is linked to various processes such as weathering, organic matter degradation, aerobic respiration, iron reduction, mineral dissolution and precipitation, cation exchange and mixing of salt water with fresh water. Multivariate statistical analyses such as principal component analysis (PCA) and hierarchical cluster analysis (HCA) were applied to the ...
Groundwater is of the most reliable sources of water for agriculture and drinking. In coastal areas due to saltwater intrusion, determine the interface between fresh and salt water for residents of these areas is very important. In this study, the characteristics of coastal aquifers West and East Babolsar, using geoelectrical studies and geo-electromagnetic studied that these methods are of the...
Climate change, which includes increases in temperature, changes in rainfall patterns, sea level rise, salt-water intrusion and a higher probability of extreme weather events such as flooding and droughts, is recognised as a global issue (Bates et al. 2008). The negative effects of these changes are likely to be felt more strongly in the less developed world compared to developed countries, as ...
