Proposal of a method for assessing combined flood risk reduction effect by hazard control measures and exposure reduction measures based on limited data.

This article verifies the applicability of an assessment method on flood risk reduction, combining and assessing hazard control measures and exposure reduction measures together. The method develops collated flood risk curves and uses limited data, so it is an approach which can be readily applied in developing countries, where an understanding of flood risk reduction measures are become increasingly important. The method was proposed as a result of studies conducted by the National Institute for Land and Infrastructure Management, Ministry of Land, Infrastructure, Transport and Tourism, Japan. When applying the method to a river improvement and relocation scheme with land mounding in Mindanao, the Philippines, the advantages and limitations of the method are considered.
