What is coastal process
What are costal processes?
The three principle marine processes that influence coasts are erosion, transportation and deposition.
What are the example of coastal processes?
Coastal Processes
- Waves.
- Tides.
- Near-Shore Currents.
- Shoreline Weathering.
- Coastal Erosion.
- Sediment Transport and Deposition.
- Organic Activity.
- Changes in Sea Level.
What is a coastal process feature?
Coastal processes create many erosional or depositional features we see when visiting the National Parks such as: Beach Ridges. Beach ridges are wave deposited sand ridges running parallel to shoreline. Wave-Cut Scarps. A wave-cut scarp is a steep bank created by wave erosion.
What are the four coastal processes?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.
Why are coastal processes important?
Coastal processes shape the physical environment, providing habitat such as turtle or seabird nesting beaches, reefs, and mangrove forests or seagrass beds.
What is coastal deposition?
When the sea loses energy, it drops the sand, rock particles and pebbles it has been carrying. This is called deposition. Deposition happens when the swash is stronger than the backwash and is associated with constructive waves.
What is marine and coastal processes?
The atmospheric processes include temperature, precipitation, and winds, while the major marine processes are waves and tides, together with water temperature and salinity. The coast also supports rich ecosystems, including salt marshes, mangroves, seagrass, and coral reefs.
What are the effects of coastal processes?
Coastal Erosion
| Factor | Effect | Time Scale |
|---|---|---|
| Rip currents | Erosion | Hours to months |
| Underflow | Erosion | Hours to days |
| Inlet presence | Net erosion; high instability | Years to centuries |
| Overwash | Erosional | Hours to days |
What does coast mean in geography?
The coast is the land along a sea. The boundary of a coast, where land meets water, is called the coastline. Waves, tides, and currents help create coastlines. When waves crash onto shore, they wear away at, or erode, the land.
