Physical and Human Factors Affecting Flood Risk

AQA GCSE Geography lesson for the 2016 specification Unit 1C: In this lesson we look at the physical and human factors affecting flood risk and storm hydrographs and what factors affect their shape.

We start with a retrieval practice quiz with ten questions. We begin by looking at the definition of flooding and a brief example by considering the floods around Doncaster in 2019 and 2020. There is a video clip for this. We then look at the physical and human factors that affect flooding. The students have a diagram to annotate and locate an appropriate example on the diagram, they then colour code the annotations into physical and human factors. We then explore the components of a hydrograph. The students have a blank graph to label on the various component parts of the graph. We then look at what factors are likely to affect the storm hydrograph. Here the students have a grid to fill in with annotations from the board. They have to locate where the annotation would logically go on their grid. We finish with a 4-mark GCSE style question and there is some tips for students who need it on how to answer it.

Hope this saves you some valuable planning time.
