Which of the major challenges in Houston could we tackle together with Dutch expertise?
Matthijs Kok (TUDelft) interviewed Dr Charlie Penland, principal at the engineering firm Walter P in Houston, with 21 USA and five international offices. Charlie's special interest is in "low-impact" development, hydraulic design, hydrologic analysis, and flood protection.

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?

Dijkwerkersdag 2022 - Towards Improved Flood Defences
On Thursday, May 12, 2022, the annual Dike Day will take place in theatre Spant! in Bussum. The research team of All-Risk will take this opportunity to present their e-book as input for the discussions and activities planned for this day.

Reflection: Looking beyond reinforcement
Implementing large-scale infrastructure projects for flood risk management requires good collaboration between water authorities, municipalities, landowners and societal organisations.

Reflection: Data-driven dike enforcements - Constructive feedback from new and historical sources
The technical assessment of dike reinforcement projects in the Netherlands is flooded with data. Before, during and after dike reinforcements, a lot of data is collected and stored. This webinar attempts to bridge the gap between conventional and new data sources by presenting new methods for improving dike safety through data and discussing the general use of different data sources.

Reflection: Foreshores - 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 into 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?

Eemdijk test: dike with sheet piles has collapsed (in Dutch)!
The test dike with sheet piles collapsed on March 17 around 4 pm. The results of this trial will be used by all dike workers in the Netherlands for years to come. They can lead to a tightening of current calculation methods, so that lighter sheet piles can be used in dikes. That saves steel and therefore money. The next step is now: to start analyzing the data obtained through intensive monitoring in the dyke and on the sheet piles.

Digital magazine of the Flood Protection Program
The Flood Protection Program (also known in Dutch as HWBP), an alliance of the 21 water regional authorities and the Dutch Ministry of Water Infrastructure are the direct users of All-Risk research. Our work is, therefore, regularly featured in their online magazine to keep all dike workers informed. See below the editions featuring All-Risk.

Modelling the waves forces on innovative covers for dikes
We developed a numerical model to investigate the usage of Grassblocks, which are placed underneath the grass cover to protect the dike against the wave forces once the grass is eroded.
