How is river flooding managed?

Lesson targeted at Year 8 but could be used at KS3 and KS4. Mini assessment of terms hard and soft followed by discussion of strategies used to reduce flood risk. When talking about how flood risk can be managed, I usually make comparison to a road and how it can become congested (flooded). If we make the road wider, then it can hold more traffic (increase capacity), increase the velocity by changing the road to a motorway or put in traffic calming (reduce discharge) to deter traffic coming down the road. Then a look at 4 strategies. Taught over 2 lessons with exam question as plenary task/ write up task.
