What is beach protection?
Coastal protection refers to the construction of structures, such as protection dykes and reinforced dunes, to safeguard developments from flood damage and erosion caused by coastal storms. These structures are designed to resist breaching and minimize the impact of severe weather on low-lying coastal areas. Many types of shoreline protection methods involve the construction of man-made structures, such as jetties, breakwaters, groins, and seawalls.Hard coastal protection methods Other shoreline protection methods include hard structures like groynes, breakwaters and seawalls. Groynes are constructed perpendicular to the coastline. They protect against erosion by reducing alongshore drift and trapping sediment.Seawalls, groins, jetties and other shoreline stabilization structures have had tremendous impacts on our nation’s beaches. Shoreline structures are built to alter the effects of ocean waves, currents and sand movement. They are usually built to protect buildings that were built on a beach that is losing sand.A beach acts as a coastal defence as it reduces wave impact and prevents inland flooding. However the beach needs to be properly managed to ensure it is wide and high enough to prevent it from being overtopped during high sea levels. This can be done through beach replenishment or beach recycling.
What are the main characteristics of a beach?
The main characteristic of a beach is the accumulation of loose particles like sand or pebbles along the water’s edge. Beaches at the ocean are often expansive and have tides that come in and out, which can create unique ecosystems with marine life. Beach management is defined as the process of maintaining or improving the conditions of a beach as a recreational resource and a means of coastal protection while providing facilities that meet user demands.
