Study Notes
Coastal Environments
- Coasts constantly change due to natural processes like waves, weathering, and mass movement.
- Coast shape depends on rock type, nearby plants/trees, and human activities.
- Natural processes like erosion/deposition create landforms: headlands, bays, cliffs, wave-cut platforms, caves, arches, stacks, beaches, spits, and bars.
- Coastal ecosystems include coral reefs, sand dunes, salt marshes, and mangroves.
- Features of coastal ecosystems: non-living things (sand, water) and living things (plants, animals).
- Human activities can damage coastal ecosystems (deforestation, building factories, tourism, farming practices).
- Conflicts arise over coastal use (conservation vs. development).
- Coastal flooding caused by storms, tsunamis, and climate change.
- People use methods like forecasting, designing flood-resistant buildings, and education to reduce the impact of floods.
- Soft engineering protects coasts by working with nature (beach replenishment, cliff regrading, ecosystem rehabilitation).
- Hard engineering involves building structures (groynes, revetments, seawalls, gabions, riprap) to protect shorelines.
- Shoreline management plans decide the best method to protect and manage specific coastlines.
