Coastal erosion refers to the gradual wearing away of the coastline due to the action of natural agents like waves, wind, and tides. The intensity of coastal erosion depends on several factors, such as the natural waves, the strength of wind, the type of rocks and sediments on the coast, and the rate of sea level rise. Additionally, the amount of human activities like coastal fishing, waste disposal, and damming of distributaries can also affect the intensity of coastal erosion. For example, excessive fishing can lead to the depletion of marine organisms that hold the sand and soil together, while the deposition of waste on the coast can alter the chemical composition of the water and soil, making it difficult for plants and animals to survive. Overall, the intensity of coastal erosion is a complex phenomenon that is influenced by both natural and human factors.
