Description
A sea level rise relative to the land that causes flooding in the area of interest, which is then below sea level. A special case of the sea level change FEP (FEP 17).
It may be caused either by a global (eustatic) sea level rise due to melting polar ice caps, or a local sea level rise due to subsidence of the land.

FEP Effects
Description of FEP Effects
Topography changes (marine abrasion = lower relief), potentially counterbalanced by subsequent deposition in coastal-marine environment. Water loading may induce subsidence or cause changes in pore structure. Changes in gradient over host rock. Changes in geochemistry. Saturation of aquifer with seawater. Dilution capacity of aquifer and groundwater flow patterns within aquifer change. Stagnant water conditions immediately above the GDF may lead to significantly reduced dilution.
