Flood Guideline

Guideline on Integrating Climate Change Projection Into Flood Risk Assessments & Mapping

Summary

Extreme hydrological events are on rise across ASEAN and are expected to intensity in scale and frequency in the future due to climate change. The main objective of these guidelines is to assist AMS conduct flood risk assessments and mapping at the river basin level by integrating climate change impacts. These guidelines and technical reports provide a holistic overview of risk assessment to assist AMS decision-making and supplement existing flood risk assessment guidelines. These specifically cover the ASEAN region and should be applied at the river basin level for integrated flood risk management and planning (IFRM). They will be useful to: 

  • Identify flood risks and vulnerabilities due to extreme hydrological events and future climate impacts
  • Conduct climate change impacts assessments and develop of realistic scenarios using the hydrological and flood inundation modeling and geospatial tools
  • Identify new, as well as hidden vulnerabilities and conduct vulnerability and damage assessment
  • Assess and map flood risks under different climate change scenarios.
  • Carryout risk planning using the principles of integrated flood management
  • Assist in the application of community-based flood risk management and planning.
