Ocean sandy beaches and coastal erosion

Saving our beaches and banning coastal real estate along fragile shorelines are very important issue that must be considered by the scientists. Many houses built on the beach lines, hit by waves, could be protected by building concrete walls, jetties and other appropriate barriers to prevent the action of waves on the properties. On the other hand, these structures would destroy the beach. Knowing how the beach system works, believing that one should not try to interfere with the natural processes that allow beaches to remain in dynamic equilibrium with waves and currents. Humans are upsetting this balance more and more by construction of huts on the coast; for paving parking lots on the beaches; and through the construction of jetties, jetties, piers and wave breakers. The consequence of these constructions carried out with little knowledge is the shrinking of the beaches in a place and expansion in another. The classic example is the containment tip built into the shore at right angles to the shore. In subsequent months and years, the beach sand disappears on one side of the point and the beach expands on the other. As landlords and builders sue each other and state governments, lawyers introduce the issue of "sand rights" into courts of law, that is, the beach's right to have the sand it would naturally contain.
