Coastal Landforms (Abrasion (Five W's and H (Where: (Along coasts or…

- - - - Need to consider coastal erosion, such as abrasion, when protecting and managing coasts.
      - Raises awareness to the public about abrasion; convinces people to move away from danger.
    - - Coastal erosion caused by abrasion can disrupt fishing; disruption of docks and shallow waters (abrasion platforms) caused by abrasion is unsuitable for boats.
      - Sediments picked up by water can choke fish. These sediments are primarily caused by inefficient fishing practices, however abrasion can cause these sediments to wear down other material, creating even more sediment, choking even more fish.
        Resulting from this, sea sponges are also being choked.
    - - This can cause houses of the community to collapse or become flooded by water.
      - At first, sea floors/coasts experiencing abrasion can be sharp and jagged, posing a risk for swimmers and boaters.
      - The eroding coastline poses a risk for infrastructure in the future.
  - - - Along coasts or edge of a body of water.
    - - Usually after hydraulic action, where waves can use the broken off sediments to wear down coasts. This process also usually occurs at high tide, as waves are able to reach cliffs and are not restricted by wave-cut platforms.
    - - A process of erosion that affects coastlines.
    - - When waves break, they create a swash. This swash will pick up material from the floor or from the preexisting wave. Inevitably, this swash will reach coasts with these sediments and erode them.
    - - It affects coastal communities; retreating coastlines will reach communities and destroy infrastructure. (More in stakeholders)
    - - Particles carried by waves are thrown at rock on the coast, wearing it away.
- - - - Can better attract customers from the beach; their industry is themed around the ocean.
      - Nearer to the source, so they can obtain fresher produce easier.
    - - Residential areas beside the beach not only provide a good scenery and access to the beach, but the proximity to the water also regulates temperatures.
      - If beaches are polluted, this can cause swimmers and others on the beach to be sick, which can cause the beach to temporarily or even permanently close, negatively impacting the coastal economy.
      - Uses beach for leisure and recreation.
      - Overuse of beach by the public may negatively impact and destroy the ecosystem. For example, sand dunes may be destroyed by unaware visitors.
    - - Tours and tourist events on the beach/coast can easily attract tourists, benefiting the industry.
      - Able to use beach scenery for tourist purposes to their advantage.
  - - - Along a coast or edge of a body of water.
    - - Beaches form when waves deposit material on a coast, which means the waves are constructive. From this, we can infer that beaches build up the fastest when the waves are formed by calm conditions (gentle winds and clear weather), making them constructive.
    - - A narrow build-up of sediments.
    - - Waves inevitably break shallow parts in water, forming a swash and backwash. If the swash is strong enough, it will deposit more sediments then eroded (constructive wave), creating beaches.
    - - It positively affects the general public; provides a place for recreation, leisure and sport. (More in stakeholders)
    - - Waves carrying sediments deposit sediments onto a coast via constructive waves (strong swash). These sediments are picked up by eroded rocks and reefs under the sea, or are eroded off the coast and taken away by a backwash, then redeposited.
