Groundwater chemistry of small tropical islands is influenced by many factors, such as recharge, weathering and seawater intrusion, among others, which interact with each other in a very complex way. In this work, multivariate statistical analysis was used to evaluate the factors controlling the groundwater chemistry of Kapas Island (Malaysia). Principal component analysis (PCA) was applied to ...

Clemen Climate change effects are expected to substantially raise the average sea level. It is widely assumed that this raise will have a severe adverse impact on saltwater intrusion processes in coastal aquifers. In th...

In simple terms, water is one of the natural resources that very important and valuable for survival humans other living things. The aims this study are to: (1) Determine distribution use boreholes; (2) Knowing level sea intrusion on ground in Kendari City. analytical methods used are: Spatial interpolation analysis to create a map boreholes using Arcgis 10.8 application; Quality assessmentbore...

T HE effects of administering sea water and similar solutions to animals, and occasionally to human beings, have been studied sporadically. Semipopular accounts of the gross effects of the drinking of sea water by shipwreck victims exist (I). During World War II the torpedoing of ships at sea and the loss of planes over open ocean, setting survivors adrift in lifeboats and on rafts, gave impetu...

Definitions and forms of salinity All natural waters contain soluble salts. The concentration of the salts determines whether the water is of high quality (drinkable or usable for irrigation without need for special precautions) or of low quality (brackish or saline). Water in the soil also contains soluble salts (sometimes called free or nonattached salts). The amount of salts in the root zone...

Salinity is the relative concentration of salts in water. In a city of southern China, the local water supply company pumps water from a nearby river for potable use. During the winter dry season, the intrusion of sea water raises the salinity of the river to a high level and affects approximately the daily life of 450,000 residents of the city. This paper reports the application of constraint ...

Both groundwater flow and mercury concentrations in pore water and seawater were quantified in the groundwater seeping site of the Bay of Puck, southern Baltic Sea. Total dissolved mercury (HgTD) in pore water ranged from 0.51 to 4.90 ng l-1. Seawater samples were characterized by elevated HgTD concentrations, ranging from 4.41 to 6.37 ng l-1, while HgTD concentrations in groundwater samples ra...

We analyze the management of a coastal aquifer under seawater intrusion using distributed control methods. The aquifer’s state is taken as the water head elevation, which varies with time and in space since extraction, natural recharge and lateral water flows vary with time and in space. The water head, in turn, induces a temporalspatial seawater intrusion process, which changes the volume of f...

Seawater intrusion, Coastal aquifer. 14Coastal zones, also referred to as the land-sea interface, are dynamic zones where terrestrial 17 freshwater biogeochemically interacts with seawater. have been recognized be 18 increasingly vulnerable contamination due dense human populations and anthropogenic 19 activities (Michael et al., 2017). Groundwater-seawater exchange is one of most important 20 ...

A coupled framework, linking subsurface flow and surface hydrodynamics, is developed applied to a real-world case study of Pingtung coastal aquifer in southwest Taiwan, East Asia. FEFLOW adopted develop 3-D variable density transient groundwater model the shallow lying 250 m below mean sea level (MSL). This with 1-D river network model, comprised main its two tributaries, using MIKE 11 through ...
