The coast is one formed by highly destructive waves. Look at the pictures to see the destructive power of the waves, and the beautiful features they formed.
Highly destructive waves, hitting the cliffs that remain standing.
The high erosive powers of the wave have shaped this coast, and signs are put up along the coast, with a red line, to warn people about the dangers.
The famous Queen's head, a sedimentary rock feature shaped by the waves' erosive power.
The new type of sea wall used to protect the coast from further erosion.
A zoomed-in view of the seawall.
Consider this: Why is it that this sea wall is not just a concrete wall, but made up of concrete pieces with such weird shapes? Think about the problems of a concrete wall along the coast, or the problems of the traditional seawall...
sea walls are built as they can absorb the energy of the wave and protect the coast against strong waves during storms.however, it has to be carefully maintianed, or the base of the sea walls may be weaken and eventually collapse. The new sea walls can distribute the energy of the waves throughoutthe whole sea wall. Reducing the amount of damages the sea wall will get and therefore the it will last longer than the traditional sea wall.

ReplyDeleteA seawall is a form of hard and strong coastal defense constructed on the inland part of a coast to reduce the effects of strong waves.Modern concrete seawalls tend to be curved to reflect the wave energy back out to sea. Poor designs require constant maintenance as waves erode the base of the seawall.Curved or stepped seawalls are designed to enable waves to break and to dissipate wave energy and repel waves back to the sea. The curve can also prevent the wave over topping the wall, and provide additional protection for the toe of the wall.

Xiu Xing is right when he says the new sea walls can distribute the energy. Think about how. If the sea wall is not a single solid piece of wall, then what can the sea water do? How does that dissipate the energy?
ReplyDeleteMiaoling has pointed out another type of seawall. It's curved, and it is another way to dissipate the energy. I'll post a picture of it soon, for all to see.
