Coastal geography focuses on the interactions between land and sea, including processes like erosion, deposition, and management. Understanding these processes is crucial for addressing coastal hazards and sustainable development.
Key Concepts
- 1Coastal erosion is caused by wave action, currents, and tides.
- 2Deposition occurs when sediment is dropped by the sea, forming features like beaches and deltas.
- 3Human activities, such as construction and dredging, can impact coastal processes.
- 4Coastal management strategies include hard engineering (like sea walls) and soft engineering (like beach nourishment).
- 5Climate change is increasing the risk of coastal flooding and erosion.
Simple Explanation
Coasts are where the land meets the sea, and they are shaped by natural forces like waves and currents. Erosion happens when these forces wear away the land, while deposition builds up new landforms. Humans also affect coasts through activities like building and dredging, which can change how coasts behave. It's important to manage coasts carefully to protect them from issues like flooding and erosion, especially with climate change.
