Coastal aquifers are increasingly threatened by seawater intrusion due to increased urbanization, groundwater exploitation, and global sea-level rise. Pattern diagrams, which constitute the outcome of several hydro-geochemical processes, have traditionally been used to characterize vulnerability to seawater intrusion. However, the formats of such diagrams do not facilitate the geospatial analys...

Geochemical evaluation of the sources and movement of saline groundwater in coastal aquifers can aid in the initial mapping of the subsurface when geological information is unavailable. Chloride concentrations of groundwater in a coastal aquifer near San Diego, California, range from about 57 to 39,400 mg/L. On the basis of relative proportions of major-ions, the chemical composition is classif...

[1] During the 1997–1998 El Niño event, the average sea surface temperature (SST) in the Taiwan Strait (TWS) in the winter was 1.4 C higher than that of the winter climatological mean. The areal ratio of the warm water ( 2 C above the regional mean) to the cold water ( 2 C below the regional mean) in the TWS increased by 25%while the area of the eutrophic water (chlorophyll a >1 mg m ) was halv...

As a semienclosed marginal sea, the Red Sea connects with open ocean through narrow strait at its southern end, known as Bab-al-Mandeb (BAM) strait. The water exchange between and Gulf of Aden BAM is crucial for mass transformations thermohaline circulation in well nutrient supply to ocean. In this study, three-dimensional high-resolution nonhydrostatic MIT general model (MITgcm) was used inves...

Estuaries are vulnerable to climate change and particularly sensitive extreme river discharge (RD) sea-level rise (SLR). To understand the effects of RD SLR on estuaries, an integrated modeling approach is adopted simulate hydrodynamic changes in Yangtze River Estuary. Model results showed that will intensify estuarine hydrodynamics water level, currents, salinity. Water current speed, salinity...
