How to Stop Beach Erosion

Erosion is a natural process that helps to transfer materials and nutrients around. However, accelerated erosion alongside the sea side can lead to elimination  of beaches and pose a threat to the property on the beach. Beach erosion is happening on a large scale around us. According to the U.S. Environmental Protection Agency, almost 80% of United States beaches have been eroding for decades and it keeps growing. Water waves wash off the sand from the beach and deposit it somewhere else, eating up on beach area. One of the main reasons for beach erosion is the ruse in sea levels that is caused by the melting of glaciers. Greater sea level has higher force to wash away larger amounts of sand from the coast. The solutions to beach erosion are pricey, time consuming but worth the effort.

Thing Required:

– Construction machinery
– Sea walls
– Dredger

Increased global warming leads to excessive melting of glaciers, contributing to sea levels.

    Human factors that contribute to beach erosion include dam building upstream the river. These dams trap the silt in the rivers and turn them hungry for sand on the beaches. Building of infrastructure on the coastline also contributes to coastal erosion. Minimal construction is advised to save the beaches for the future.
