Answer:
The following practices and methods can help coastal areas cope with coastal erosion, submersion, and saltwater intrusion.
Coastal Protection
Some structures and methods can help protect the coasts from erosion and submersion. They are usually constructed along the coasts.
Seawalls and bulkheads are structures that are built parallel to shores that protect the coasts from wave actions.
Groynes and jetties are structures that are built perpendicular to shores to prevent coastal erosion by promoting beach build-up as they trap sand.
Breakwaters are offshore structures that protect coasts from parallel waves and in turn, prevent erosion and submersion.
Beach nourishment is a method where a large amount of sand is added to the coasts. This will create a new beach or widen an existing one. However, this method is costly which deters communities to use it.
Sandbags are used to counteract waves that hit the shores. They also diminish the effect of a storm surge that can cause submersion.
