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 assignment2.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.Print ’762.Color lost farmland3.Make 10 m grid4.Count up lost area5.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
Sea level change curves
Approx. last major glacial
event
~6000 YbpPretty close to today…

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
