Structures built to protect beaches
Compare and contrast seawalls and groins
Seawalls are solid structures built along the coast to absorb and deflect the energy of incoming waves, reducing their erosive power. By acting as a barrier, seawalls help to protect the shoreline from erosion caused by the force of waves and tides. However, seawalls can also have negative impacts on coastal ecosystems and may lead to increased erosion in adjacent areas due to changes in sediment transport patterns.
Build groins and seawalls is one example of what you can do.

Seawalls provide protection against erosion and storm surges, helping to prevent coastal flooding and property damage. They can also provide a stable foundation for structures built near the coast and can protect valuable land from being swept away by waves. Additionally, seawalls can help preserve coastal habitats and biodiversity by reducing the impact of wave erosion.
One engineering strategy that has been used to protect coastlines from erosion is the construction of seawalls. Seawalls are vertical structures typically made of concrete or rock that are built along the shoreline to absorb and deflect the energy of incoming waves, reducing their erosive force on the coast. Seawalls can help prevent coastal flooding and erosion by providing a barrier between the sea and the land. However, it's important to consider the potential impacts of seawalls on coastal ecosystems and natural sediment transport processes when implementing this strategy.
The term that refers to someone who is effective, organized, and competent is "efficient."
That would depend on various things: Effective against what?; and used by whom? ; how will they use the weapon?; do they fully understand how to use it?
all costal areas that lack a natural barrier. ie..Reef, Mountain Range..etc...
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.
If someone contracts rabies then it should ideally be treated straight away. If it is administered quickly the treatment can be effective.
