Natural barriers, such as reef and mangrove forests, prevent the spread of tsunamis and the circulation of seaside waters and alleviated the flooding and surge of water. A cost-benefit strategy is an effective method to determine whether a seawall is ideal and whether the advantages are worth the expenditure.

This can create coastlines to dissipate, rendering them worthless for coastline goers. Generally, seawalls can be an effective way to control seaside erosion, however just if they are created well and out of products that can stand up to the pressure of recurring wave energy. Some understanding is needed of the coastal processes and morphodynamics certain to the seawall location.


Superstorm Sandy sent out a storm rise of 45 m onto New Jacket's and New york city's barrier island and metropolitan coastlines, approximated at $70 billion in damage. This problem could be conquered by additional modeling and figuring out the extension of height and support of present seawalls which needs to occur for security to be ensured in both scenarios.

, rainfall percolating into the ground behind the wall surface and waves overtopping the wall surface.


The addition of seawalls near marine communities can result in raised watching results in the waters bordering the seawall. Trailing minimizes the light and visibility within the water, which may interrupt the distribution along with foraging capacities of certain varieties. The sediment surrounding seawalls has a tendency to have much less favorable physical homes (Greater calcification levels, less architectural company of crystalline framework, low silicon content, and less macroscale roughness) when contrasted to all-natural coastlines, which can present concerns for species that reside on the seafloor.

However, the former French colonial enclave of Pondicherry ran away unscathed. This was mostly because of French designers who had built (and maintained) a huge stone seawall while when the city was a French nest.
