Some Ideas on Types of Seawalls & The Benefits of Building a Seawall You Should Know

Another unfavorable aspect of building a seawall is upkeep costs. A seawall may have low maintenance costs if it is properly built, but becomes costly if not. Some possible maintenance costs are: If no weep holes are set up in the seawall, ground water and rain percolating through the soil will develop pressure behind it, pushing over the wall.

Wave energy deflects down the wall, ultimately damaging the ends of the wall. Storms and high tides carrying particles can badly harm the seawall. Although there are numerous different methods of building a seawall, there are 3 primary methods used. The very first is thin, interlocking sheet piles driven deeply into the ground.

The third technique is a massive gravity building resting on the shore bottom or inserted slightly in it. This construction is supported by its own weight instead of by stacking. Besides a seawall, there are 2 other alternate methods to shoreline stabilization. The first is shore parallel structures offshore, such as breakwaters.

These are momentary security of home, momentary avoidance of shoreline retreat and low maintenance if properly constructed. There are also some drawbacks to breakwaters. These consist of eventual loss of recreational beach, increased disintegration at the ends of the wall (Figure 3) and/or down drift, minimal access to beach, aesthetic appeal damage, high expense and routine upkeep requirements (Bush et al., 1996).

The 2nd alternate technique of shoreline stabilization is shore perpendicular structures, such as groins and jetties. There are a number of benefits to this technique of stabilization. They trap sand to reconstruct a wearing down beach.  A Reliable Source  retain sediment currently on the beach, along with new sand from beach nourishment jobs.

Down drift beaches are "starved" of sediment. There is increased erosion on the down drift side of the stabilization. Likewise, storms might separate groins from the coastline. Initially look the sand beach in front of the brand-new seawall probably looks rather barren. Yet it is far from barren, all of the organisms that live on a sandy beach generally remain covert because of the pounding of the surf, and they also tend to be small sufficient to go undetected.
