To research if the current practice of mandating individual flood risk assessments supports the goal of an optimal flood risk a case study is performed in this thesis. The flood risk in 2050 is assessed for the liquid bulk storage terminals of the company Vopak located in and near the Botlek area of Rotterdam harbor. The used flood risk assessment method in this case study enables a quantitative risk evaluation in which there is a distinction between four risk categories; fatalities, environmental, economic and reputation risk.
