Interview with Jan Hateboer (Fryslân water board): dike reinforcement requires area-based collaboration

Jan Hateboer (project manager at Fryslân water board) shares in an interview with Martijn van Staveren (All-Risk researcher) his experiences with the implementation of the new safety norms on the dikes of the Wadden Sea. He suggests adopting an area-based approach, look for improved coordination between government partners and better customization of dike reinforcement projects to be smart and efficient.

NCR Lecture: A system perspective on flood defence reinforcement projects

Wouter Jan Klerk talked on the NCR December's lecture about the Dutch flood probability standards, and how he works to optimise the way we reach our risk-based target levels. In the dike reinforcement Streefkerk-Ameide-Fort Everdingen a method was developed and applied to optimize flood defence investments at a system level.

Reflection: Forelands - useful for manageable flood safety or just beautiful nature?

In the 19th and early 20th centuries, salt marshes were mainly created for agriculture in the North of the Netherlands. More recently, we have reconsidered the value of these vegetated foreshores for flood safety.

Reflection: Risk-based inspection and interactions between failure mechanisms

Safety standards of flood defences are based on probabilities of flooding. Using a variety of failure models and statistical methods, we try to assess these probabilities as good as possible, in order to take effective measures for flood risk reduction. The question is how well we actually have insight in the flooding probability, and whether we take all relevant factors into account.

Reflection: Macro stability - better parameters or models or do we need to reinforce the dikes?

Macro instability of the inner slope is an important failure mechanism that has a large influence on the costs of dike reinforcements and their impacts on the landscape. There are various uncertainties considering the strength parameters and models. There seem to be various options when a dike does not meet the standards: better parameter estimation, better models, or realize a conservative and expansive reinforcement. Which options could we explore to deal with macro instability in an efficient manner?

Reflection: Towards a realistic approach of resistance against wave overtopping

Wave overtopping results in a high hydraulic load on the dike cover and can lead to erosion of the grass cover. The overtopping research in the All-Risk program was focused on two aspects: methods for the outer slope and methods for the inner slope.

Reflection: The biggest flood risk in the rivers - bifurcation points or piping?

Flood risk along the Rhine branches: Flood risks along the major rivers continuously demand our attention. During this All-Risk webinar, we called attention to new research on the role of two of the mechanisms that influence flood risk: the two main bifurcations of the Rhine branches and the role of the failure mechanism piping. Can it be plausibly argued that one of the two causes are dominant?
