Seawalls are massive structures which are designed to prevent coastal erosion and other damages due to wave action during huge storms such as hurricanes.
My family used to live near one. It are very satisfying to watch during rain storms, because you can hear the sound of the rain falling on top of it. I also loved watching the waves hit the sea wall then roll back down.
Hope this helps. ( Sorry I go a little carried off)
Seawalls, groins, jetties and other shoreline stabilization structures have had tremendous impacts on our nation's beaches. Shoreline structures are built to alter the effects of ocean waves, currents and sand movement. They are usually built to "protect" buildings that were built on a beach that is losing sand.
