2. Flooding and flood mitigation

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)
    • Two contrasting detailed examples of flood mitigation of drainage basins
