Each flood defence system along the river Meuse needs to be provided with a safety level with an annual failure probability of 1/250. In the nearby future a new safety philosophy will be introduced, entailing new safety norms and calculations techniques. The water board needs to construct levees including the knowledge of this new safety philosophy. Additionally the water board faces more problems like limited space or an intense infrastructure around the current levees. The objective of this MSc-thesis is to investigate which balance between levee investments and robustness is most cost-effective during the levee design alternative analysis, specified for cases along the river Meuse in Limburg. Robustness within this balance is related to the uncertainties in future hydraulic boundary conditions. Life Cycle Cost Analysis or LCCA is a widely acknowledged technique to support the alternative analysis. One of the methods is the so called Net Present Value (NPV) calculations which include investments as well as benefits. This method suits perfectly to investigate the robustness and the effect of hydraulic boundary condition uncertainties to the alternative analysis. Within this research three different hydraulic boundary condition uncertainty aspects are analysed: The uncertainty in future river widening projects, the uncertainty in statistics and the uncertainty in forecasted climate changes. Two case studies are assessed along the river Meuse in Limburg; Location Arcen and Venlo. For both cases, levees alternatives are defined designed and screened. The resulting alternatives are analysed on their LCC. The cost-effective levee designs along the river Meuse in Limburg are robust in terms of height and are designed with the requirements of the new safety philosophy. LCCA is an appropriate tool to investigate levee design alternatives on a cost-effective manner. Accounting project investments only lead to an unfair alternative analysis. Including uncertainties in hydraulic boundary conditions during the alternative analysis does not lead to another outcome. These uncertainties do contribute to the investigation of the optimal levee height robustness.
