Looking for a solution for flooding water.
a sea wall is a wall built to protect land along the coast from erosion and flooding from the sea. while they do provide protection from the waves and tides, a sea wall may also create more problems. erosion of beach sand may increase because of the wall, and the wall may change the direction and flow of waves and caused erosion in other places.
