Numerical Modelling of Seawater Intrusion in Manukan Island's Aquifer

A numerical model SEAWAT-2000 was developed to investigate the current seawater intrusion status in the low lying area of Manukan Island. SEAWAT-2000 output indicated that there is about 1.4% of freshwater and seawater mixing ratio at sea level in low lying area of Manukan Island illustrates the seawater intrusion problem. Upconing process simulated by SEAWAT-2000 showed the current status of s...

Impacts of seawater rise on seawater intrusion in the Nile Delta Aquifer, Egypt.

Several investigations have recently considered the possible impacts of climate change and seawater level rise on seawater intrusion in coastal aquifers. All have revealed the severity of the problem and the significance of the landward movement of the dispersion zone under the condition of seawater level rise. Most of the studies did not consider the possible effects of the seawater rise on th...

Numerical Modeling of Seawater Intrusion in Coastal Aquifer Using Finite Volume Unstructured Mesh Method

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...

Derivation of a Sharp-Diffuse Interfaces Model for Seawater Intrusion in a Free Aquifer. Numerical Simulations

We derive a new model for seawater intrusion phenomena in free aquifers. It combines the efficiency of the sharp interface approach with the physical realism of the diffuse interface one. More precisely, a phase field is used as an intermediate variable for including the exchanges between the characteristic layers of the aquifer (salt water, fresh water, unsaturated zone). The threedimensional ...

Preliminary study on seawater intrusion and aquifer freshening near reclaimed coastal area of Shenzhen, China

Local groundwater in coastal aquifers in Shenzhen has experienced heavy pumping since the 1980’s when Shenzhen began to expand very quickly from a fishing village to a modern city but lacked a public water supply. Meanwhile, large-scale land reclamation was carried out to meet the needs of various urbanization projects. In this paper we analyzed groundwater from a coastal aquifer system in Shen...
