Beach

In understanding coastal and coastal areas almost all of us know the beach but often also do not understand what the definition of the beach, therefore from our understanding many mistakes, for example by making beaches with coastal equations and different beaches are almost equal.

In the coastal sense is the meeting area between the sea water and the soil that eventually happens called the tide and low tide even when it comes a storm, though not often occur.
The coast is an area that starts from coastal areas to far to the mainland. There is no definite or clear boundary regarding the coastal area but clearly the coastal area is part of the coastal area itself.
