Going to the Beach? Instructions on Completing Activities for the Coastal Geomorphology Laboratory Activity 1: Analyze sea cliff loss Task 1: Calculate erosion along the Suffolk coastline in the U.K. using ground survey SUBMISSION IS ADVANCING AT A FRIGHTFUL SPEED 1 meter per flag Task 1: Calculate erosion along the Suffolk coastline in the U.K. using ground survey • Finish table • Calculate erosion rates Task 2. Analyze change in a coastal landslide using aerial photography Looking east Task 2. Analyze change in a coastal landslide using aerial photography Bluff (small cliff) retreat from landsliding: how fast? how much? Task 2. Analyze change in a coastal landslide using aerial photography Task 2. Analyze change in a coastal landslide using aerial photography Analyze 1976 and 1995 and then answer: how much farmland has been lost (sq. meters) and how fast? 1. Download these files from the web page version of the assignment 2. Print ’76 Task 2. Analyze change in a coastal landslide using aerial photography Analyze 1976 and 1995 and then answer: how much farmland has been lost (sq. meters) and how fast? 1. 2. 3. 4. 5. Print ’76 Color lost farmland Make 10 m grid Count up lost area Measure biggest distance lost & calculate rate of retreat Task 3. Analyze change at Point Reyes using a historical map Task 4. Compare rates of cliff retreat Activity 1: Task 5 Calculating very long-term rates of cliff retreat using offshore rocks and sea stacks Approx. last major glacial event ~6000 Ybp Pretty close to today… Sea level change curves Activity 1: Task 5 Calculating very long-term rates of cliff retreat using offshore rocks and sea stacks (10 points) Activity 1: Task 5 Calculating very long-term rates of cliff retreat using offshore rocks and sea stacks Overview of Activity 2 You study change in depositional (beach) contexts, using a mixture of maps, aerial photography, and satellite images. Activity 2 • Task 1. Analyze human modification of California beach: Humboldt Bay • Task 2. Analyze change accomplished by major storms – Study the effect of Hurricanes on the Dauphin Island (a barrier island) Task 1. Analyze human modification of California beaches You analyze Humboldt Bay Task 1. Analyze human modification of California beaches You analyze Humboldt Bay… add Jetties Task 2. Analyze change accomplished by major storms Task 2. Analyze change accomplished by major storms Draw out the area lost, using scale
