Coastal erosion is a natural process that slowly wears away land along the shore. Here are the main reasons it happens:
Wave Action: Strong waves, especially during storms, crash against the beach and cliffs, wearing them down.
Human Activities: Building things like sea walls and jetties can mess up how sand moves naturally, which can make erosion worse in some spots.
Sea Level Rise: Climate change is causing oceans to rise. This makes erosion worse because the water can reach further onto land.
To help reduce erosion, we can use different methods:
Soft Engineering: This includes adding sand to beaches that are eroding. It helps to restore and keep the coastlines healthy.
Hard Engineering: This means building strong structures like sea walls and groynes that block waves. But sometimes, these can lead to more erosion in other areas.
Managed Retreat: This approach allows some areas to erode while moving buildings and roads to safer spots. It can be a better long-term solution.
A good example of managing coastal erosion can be found in the Netherlands. There, they use a mix of dikes and smart land planning to protect their coasts from erosion and flooding.
Using these strategies is really important for keeping our coastal areas safe!
