to prevent land from erosion and flooding
As a preventive measure, Japan should build sea wall for a height of 30 feet or more for their coastal cities and towns on the eastern coastal areas in order to stop and avoid Tsunami waves coming ashore and distroy all their homes, factories and infrastructures. I wonder how this idea did not occur to their smart minded people for so long. I do not expect the sea wall will stop all the waves of Tsunami but the force of the waves will be greatly reduced and the water will jump only if the height of the wave is only more than 30 feet ( height of sea wall). With oceanographers and structural engineers, the design of the sea wall may not be a problem. Offshore oil field stuctural piles may be taken as models to build the foundation for such sea walls and the depth about 150 feet to 200 feet piles can be inserted into the seashore for keeping the wall intact while a large Tsunami waves attack the wall. Initial cost of constructing the wall may be highly expensive but considering the long term benefits and the avoidance of natural calamity and the loss of lives and properties of the Tsunamis such happened recently in Japan northeastern coast would be cost effective. -- Jaffarullah@gmail.com
A sea wall is a wall or embankment erected to prevent the sea from encroaching on or eroding an area of land.

The Sea Wall was created in 2008.
so they could cross over the sea
No sea borders the Great Wall of China. The Great Wall of China is on land, facing toward Mongolia. The nearest sea to the Great Wall of China is the Yellow Sea.
Erosion will occur eventually, the water will eventually break through the sea wall and start eroding the houses built behind it. Sea walls are also very expensive to build, they take up a lot of the money from the local government, which means that taxes will increase for the residents in that particular area.
the curved sea wall deflects waves from getting onto shore
The lifespan of sea walls can vary depending on factors such as the materials used, maintenance practices, and environmental conditions. Generally, properly maintained concrete sea walls can last 30-50 years or more before needing significant repairs or replacement. However, natural disasters and extreme weather events can significantly impact the longevity of sea walls.
You can find an aquifer in the ocean right near the sea wall.
A sea wall is a concrete wall used to defend the coast against coastal erosion.
The purpose of a sea wall is to provide a barrier between the sea and land (specifically areas that are heavily populated). This provides protection against sea actions such as tides and waves.
