Coastal Erosion

Comments (0)

The Nuffield Foundation provides this resource which shows students how, given a set of measurements along an irregular coastline, it is possible to approximate the area of land which is lost to coastal erosion over a period of time.

Coastal erosion A - this activity uses the context of coastal erosion to introduce the trapezium rule for estimating the area under a curve. The activity can be presented using the slideshow and related material on the internet.

Coastal erosion B - has the same example and exercises, but with functions modelling the coastline so that the areas can be determined using integration. There is also a natural extension that relates to introducing and using rates of change, the land loss due to coastal erosion.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
