Discussion
State whether the following is true or false.
A single storm's erosion is not evidence of a long term erosion trend.
Answer: B
Correct answer: True
Storm erosion is largely cross-shore: sand is drawn offshore into bars and returns over the following calmer months. A trend requires a net loss from the system, which is a matter of the sediment budget rather than of any one event. Acting on a post-storm survey as though it showed a trend has led to a great deal of unnecessary defence, which is why the distinction is drawn so firmly.
