Water stress build-up is triggered when groundwater is not drained pipes from behind the seawall. Groundwater against a seawall can be from the location's natural water-table, rainfall percolating into the ground behind the wall surface and waves overtopping the wall surface. The water level can likewise climb throughout periods of high water (high tide - shoreline protection.
