Atoll-island groundwater

Detailed Description

Conceptual diagram showing impact of sea-level rise and wave-driven flooding on atoll-island groundwater. (A) Current sea level. (B) Future sea level. Sea-level rise will allow for greater wave heights (H) and wave-driven runup (R), resulting in frequent overwash that will contaminate the atoll island’s freshwater lens. Note: Heights are exaggerated. From article by Storlazzi and others, Science Advances 4:4, published April 25, 2018.
