A large number of coastal aquifers are threatened by saltwater intrusion. Saltwater intrusion may occure due to human activities and by natural events such as climate change and sea leael rise. In coastal aquifers, overabstraction due to high demands for domestic water supply is the main cause of saltwater intruson. Also the rise in sea level due to the climate change accelerates the saltwater intrusion into the aquifers which reduces the fresh groundwater resources. With the impact of sea level rise and overpumping combined together the problem becomes even more serious and requires fast solutions. Coastal aquifers are affected by the rise in the sea level due to climate change and global warming. It is estimated that the mean sea level will rise in a range between 20 to 88 cm during the current century. The rise in sea level will shift the saltwater interface further inland. As a result, the extraction wells that were originally in fresh groundwater, may then be located in brackish water or saline water and upconing may occur. Consequently, the abstraction rates of these wells may have to be reduced or the wells abandoned. This is considered one of the most serious impacts of sea level rise. Therefore, saltwater intrusion due to sea level rise should be predicted and prevented (or at least controlled) to protect groundwater resources.
