For the Instructor
These student materials complement the Coastal Processes, Hazards and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Summative Assessment
Answer the questions in the worksheet
- During which of the time periods are the sand dunes of the island most evident in the profile data?
- Which of the profile transects had the highest sand dunes during this time period?
- Which had the lowest sand dune during this time period?
- Which of the profiles had the widest horizontal extent of sand dunes? Approximately how wide were they?
- During which of the time periods were the sand dunes the most reduced in elevation?
- Why were the dunes reduced? Provide some explanation about where this sediment may have gone.
- During which time period did the greatest amount of erosion take place on the island relative to the baseline survey date of February 1, 2008? Explain why you think that this erosion took place.
- For each survey transect location (1-3), indicate where along the transect the most significant erosion take place during the three survey dates. For example, did the most amount of erosion on transect 1 take place at the beach face or in the dunes between the first and third survey?
- Which of the 3 transects shows the greatest amount of net deposition in the dunes during the post-Hurricane Alberto recovery time period?
- Which of the profiles shows the greatest amount of net deposition in the intertidal zone during the post-Hurricane Alberto recovery time period?
Before you turn in the file, don't forget to add the files that you created earlier in the activity. You should have saved 3 transect plots.
Submit your responses following the directions that your faculty member gives you.
