The day of the dike worker Emma Avoyan
The All-Risk research is particularly useful to the Dutch Protection Program (HWBP). Such is the case of Emma Avoyan researcher at Radboud University into the collaborative efforts of the dike reinforcement projects so that the HWBP magazine featured a day of her work.

Workable water management - experiences on interdisciplinary collaboration
Lawyer Marleen van Rijswick and engineer Matthijs Kok are working together on workable innovations in water management. On this blog, they share the experiences from their interdisciplinary collaboration for a new call of the Netherlands Organization for Scientific research (NWO) that stimulates such approach. This interview was carried out by Sonja Knols-Jacobs and first published on the NWO website.

Reflection: Better mapping of the subsurface
How can we make better use of subsurface information to improve the parameter estimates of models that determine the occurrence of piping, slide flow of channel banks or other failure mechanisms of river dikes?

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 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.
