Red River Case Study:
- Identify the type of drainage basin.
- Where does the Red River drain into?
- Use specific characteristics to identify the age type of the Red River.
- What type of soil is most common? Explain why.
- On the “Pattern of lateral channel migration” map, indicate where there would be erosion, deposition and levees
- Sketch how this area would look if oxbow lakes were formed
- Explain what some appropriate land uses for flood plains would be.
- Which flood year was the worst for Winnipeg? Explain why.
- See “TOP 10 RED RIVER FLOODS SINCE 1800”, how can you explain why in 1826, the river was only 2 feet higher than in 1852 yet there was an extra 60,000 cubic feet of water whereas between 1996 and 2006, there was a similar rise in the river but only 9000 more cubic feet of water.
- Why does this make flooding around the Red River more dangerous than an area like Vancouver at the end of the Fraser River?
- Explain how floodways on the Red River work to keep Winnipeg safe.
- What secondary system is in place to protect the Red River Valley from floods? Explain how it works.
- Why would ice mitigation help prevent a flood?
