Coastal Management
step 1 Aim:
To examine the interaction of physical and human elements of the coastal environment and to understand the importance of active, responsible and informed citizenship for a sustainably managed, socially just and equitable coastal zone.
Step 2
Four Focus Questions 1. How has the coast change over time? 2. What has been the impact of humans on the coast overtime? 3. Should the development continue 4. How can the coast be sustainably manage? What strategies could we use?
The continental shelf, continental margin, coastal ocean and coastal zone are fuzzy concepts for which various definitions have been proposed.The two main processes involved in the formation of coastal landforms are erosion and deposition.
Coastal Zone
The two mainly processes in involved in
the formation of coastal land forms are Erosion and Deposition
Erosion
Plunge pool undercuts hard rock which collapses. George cut as waterfall moves back
Softer rock erodes more quickly
Plunge pool
New plunge pool
Coastal erosion results from beach-ocean interaction coupled with human activity. The beach system is one that is considered to be in dynamic equilibrium. This means that sand is moved from one location to another but it does not leave the system. For example, winter storms may remove significant amounts of sand, creating steep, narrow beaches. In the summer, gentle waves return the sand, widening beaches and creating gentle slopes. Because there are so many factors involved in coastal erosion, including human activity, sea-level rise, seasonal fluctuations, and climate change, sand movement will not be consistent year after year in the same location.Wind, waves, and longshore currents are the driving forces behind coastal erosion. This removal and deposition of sand permanently changes beach shape and structure. Sand may be transported to land-side dunes, deep ocean trenches, other beaches, and deep ocean bottoms. Coastal erosion poses many problems to coastal
