Study Notes
Coastal Environments
- Coasts constantly change due to natural processes like waves (erosion, deposition, transport), weathering, and mass movement (landslides, slumping).
- Coastal environments are affected by rock type, nearby plants/trees, and human activities.
- Changes in sea level over time also impact coastal environments.
- Natural processes create various coastal features: headlands, bays, cliffs, wave-cut platforms, caves, arches, stacks, stumps, beaches, spits, and bars.
- Coastlines have unique ecosystems, including coral reefs, sand dunes, salt marshes, and mangroves.
- Coastal ecosystems include living (plants and animals) and non-living (sand, water) components.
- Human activities can damage coastal ecosystems, such as deforestation, building factories, farming, and tourism.
Coastal Management
- Conflicts arise because different groups use coasts for various purposes (conservation vs. development).
- Coastal flooding occurs due to storm surges, tsunamis, and rising sea levels.
- Forecasting, flood-resistant building design, and public education can reduce flooding impacts.
- Coastal protection methods include:
- Soft engineering (beach replenishment, cliff regrading, ecosystem restoration): working with natural processes
- Hard engineering (groynes, revetments, sea walls, gabions, riprap): structural interventions
- Shoreline management plans are crucial for deciding how best to protect specific coastal areas long-term.
