Local communities have taken a number of approaches to solving the problem of shrinking beaches. one direct, but relative expensive approach is to a beach by dumping tons of sand just slightly upcurrent of the beach.

One direct, but relative expensive approach is to PUSH a beach by dumping tons of sand just slightly upcurrent of the beach.

Explanation: Shrinking Beaches can be defined as the displacement of land, or long-term removal of small particles (beach sand) and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, or other impacts of storms.

When a beach is shrinking also known as beach erosion, to prevent the beach from shrinking any further, addition of sand and rocks will minimise the effect of the erosion and might as well stop it in the long term . The sand may be dredged from nearby and pumped onto the beach, or transported in from outside areas.
