fw.2 Flooding and flood mitigation
Unit Contents
fw.2 Flooding and flood mitigation is part of the Freshwater geographic theme (Paper 1). The geographic inquiry for this sub-topic is: how physical and human factors exacerbate and mitigate flood risk for different places
Geographic inquiry: How physical and human factors exacerbate and mitigate flood risk for different places
- Hydrograph characteristics (lag time, peak discharge, base flow) and natural influences on hydrographs, including geology and seasonality
- How urbanization, deforestation and channel modifications affect flood risk within a drainage basin, including its distribution, frequency and magnitude
- Flood mitigation, including structural measures (dams, afforestation, channel modification and levee strengthening) and planning (personal insurance and flood preparation, and flood warning technology)
