Understanding the Causes of Coastal Erosion

Natural Causes

Coastal erosion is a complex phenomenon that can be attributed to a combination of natural and human-induced factors. Among the natural causes of coastal erosion are wave action, tides, and longshore drift. Waves exert a powerful force on the coastline, gradually eroding the land and carrying away sediment. Tides also contribute to erosion, particularly during storm surges when high tides can inundate coastal areas and cause significant damage. Additionally, longshore drift, the movement of sediment along the coast, can lead to the gradual loss of beach material.

Human Activities

While natural forces play a significant role in coastal erosion, human activities have greatly exacerbated the problem. Beachfront development, for instance, has altered the coastal landscape by removing natural protective barriers such as dunes and vegetation. This alteration disrupts the natural balance of sediment movement, leading to increased erosion. Improper land use practices, such as deforestation and excessive agriculture, also contribute to coastal erosion by removing vegetation that stabilizes coastal soils. Furthermore, climate change, driven by human activities, has led to rising sea levels and increased storm intensities, both of which contribute to accelerated coastal erosion.
