  • 3. Conclusion
  • The benefits of the integration of flood risk management

into wider development management, urban planning and climate change adaptation are clear;

  • The most successful long-term flood risk management

strategies will balance the implementation of short-run, quick gain, non- structural measures with a vision of the best suite of structural and non- structural measures to be implemented for the longer term;

  • Understanding the required resources, the best and worst

case scenarios and the tipping points at which action becomes imperative, rather than justified, can lead to better decisions.

  • The benefits of the integration of flood risk management
