Quantifying multiple planning objectives of flood adaptation measures – a case study of Odense, Denmark

It is difficult to implement urban flood adaptation measures due to organisational and financial barriers. We quantify and value planning objectives of urban flood adaptation measures in relation to urban planning. The purpose of doing so is to be able to frame adaptation projects to attract relevant stakeholders, e.g. by changing the framing from “reduce flood damage” to “improve urban areas”.

Studies quantifying the effect of measures and primary valuation studies are searched for in literature, being electronic journal databases and existing tools and databases. We focus on studies that differ in time and space to get a better understanding of the indicators to improve our project estimates.

We apply preliminary findings to a case study in Odense, Denmark. The results show that objectives of increasing air quality and physical health are dominating. The results show a high sensitivity to the initial input values used to calculate the indicator and to the aggregation method. This stresses the importance of understanding indicators better to not under- or overestimate the contribution of measures to the targeted planning objectives.
