A seawall provides a defense for canals and bays. Seawalls minimize the eroding impact of the ocean waves and reduce the waves’ energy to protect the nearby land and its inhabitants.
Essentially, seawall construction redirects the waves back to the sea, curbing potential damage and erosion over time. Hence, seawall construction procedure is performed to protect structures and pedestrians from the harmful effects of waves.
There are two different seawall types: vertical walls and riprap embankments. Each does the same job in a different way, but one option may be more suitable than another in a particular situation.
Vertical seawalls are fairly easy to construct, and they can adequately deflect wave energy to protect the coastline. Essentially, they’re upright, sturdy walls that block waves from damaging the coastline. To make the walls more effective, piles may be installed in front of the wall to diminish the wave energy a little and curtail the impact of the wave.
Riprap embankments, or revetments, are great for low-impact areas, and they’re rather cheap. They don’t do well against heavy waves, but they can break up the wave energy of a small wave, lowering the erosion impact of the wave and protecting the coastline.
A riprap embankment basically starts with a rubble mound, and the side of the mound exposed to the sea is covered in porous rocks, sandbags, or stones.
