Here is a screenshot from my lesson plan:
this image shows settlements in the area, the color of the circle shows how 'sensitive' they are to flooding and the size the population.
this image shows the same area with a red overlay of what has been flooded from the google project. The two translucent areas show regions I identified in the lesson plan as;
- North area: poor people living close to the river
- South area: richer people living further from the river.
