Description Project Description
The small island developing states (SIDS) are the first to be hit seriously by sea level rise and climate change. Besides increased flooding and coastal erosion, freshwater lenses below islands will shrink and fresh groundwater reserves will be reduced significantly. The migration of climate refugees from SIDS to the continents is inevitable when we are not able to find a solution to protect the precious fresh groundwater reserves below these islands.

Research question
Which hydrogeological conditions control the size of fresh groundwater lens on atoll islands in the Pacific Ocean and how can these lenses be protected against sea level rise and climate change?

Method
A sensitivity analyses will be carried out by numerical modelling of different kinds of islands showing the variation of the above-mentioned characteristics. The models will be constructed with SEAWAT
