Abstract: | All over the world flooding is experienced, which can result in casualties and large monetary damages. This study focuses on the potential of spatial measures to reduce flood risk in the Netherlands, a flood-prone country with strict safety standards. First, the influence of model complexity on the derived safety standards is assessed, in order to make a comparison between effectiveness of calculated measures and model uncertainty. Next, spatial measures from were ranked using interviews. Lastly, measures were evaluated by comparing their investment costs with the added benefits of the measures. Two different spatial measures were evaluated, namely heightening a highway using a temporary flood defence and decompartmentation by removing a regional dike. The temporary flood defence measure showed to be effective to decrease the total amount of monetary damages and the total costs when including investment costs. However, north of the highway locally flood risk is increased because of the increased water depths. The decompartmentation measure is effective in reducing the local individual risk (LIR). However, it does increase monetary risk, as a result of the increased number of victims and monetary damage. |
