Have students write a story from the perspective of a sand grain on the Willemar Bluffs as it moves down the bluff, along the shore to Goose Spit and beyond.
What things are a factor in erosion? And how do they change erosion? Trees (vegetation) decrease erosion, slope – steeper increases erosion, storms increase erosion, winds- high winds increase erosion, more rain increases erosion etc…
What happens if we protect the Willemar Bluffs from eroding (install armouring such as rocks and riprap at the bottom)? The beaches in front of the bluffs decrease as does Goose Spit, eventually the armouring may fail.
Why do we want to protect the bluffs from erosion? Houses and properties. What are our other options? Don’t live on a bluff, move the house further back from the bluff.
