Failure probability by wave overtopping over grass-covered and damaged dikes

van Bergeijk, Vera M.; Warmink, Jord J.; Hulscher, Suzanne J.M.H. - 03/03/2021 - All-Risk
We calculate the failure probability by wave overtopping of grass-covered and damaged dikes and show that damages to the dike cover, such as an animal burrowing or an erosion hole, can increase the failure probability significantly.

Optimal planning of flood defence system reinforcements using a greedy search algorithm

Klerk, W. J., Kanning, W., Kok, M. & Wolfert, R. - 01/03/2021 - All-Risk
We ontwikkelen en valideren een zoekalgoritme wat de optimale combinatie van dijkversterkingsmaatregelen op systeemniveau zeer nauwkeurig benadert. Toepassing op een lopend dijkversterkingsproject leidt tot een kostenreductie van ongeveer 40% in vergelijking tot de gebruikelijke aanpak.

Optimal planning of flood defence system reinforcements using a greedy search algorithm

Klerk, W. J., Kanning, W., Kok, M. & Wolfert, R. - 01/03/2021 - All-Risk
We develop and validate greedy search algorithm that can find (near-)optimal combinations of reinforcement measures for dike segments. The approach was applied to an ongoing reinforcement project, and it was found to reduce investment costs by ~40% compared to the conventional approach.

Stormingskenmerken bij de "Pannerdense Kop"-splitsing

11/02/2021 - Rivers2Morrow
De stromingsstructuur verschaft hierover nuttige informatie door de driedimensionale kenmerken van de stroming te detailleren. Deze samenvatting gaat voornamelijk over enkele waarnemingen van de ADCP-onderzoeken die tussen november 2019 en februari 2020 op de Pannerdense Kop zijn uitgevoerd.

Insight into the local bed-level dynamics to assist management of multi-funtional rivers

van Denderen, R. P., Paarlberg, A. J., Augustijn, D. C. M., & Schielen, R. M. J. - 11/02/2021 - RiverCare
River discharge fluctuations cause bed-level variations at various scales, resulting from spatial gradients in the river’s geometry. Insight into these bed-level variations and their relation to discharge fluctuations can help to predict and prevent the formation of local bottlenecks. In this paper, we use bi-weekly bed-level measurements of the river Waal to estimate the bed-level variations related to the river discharge.

Laying bare systemic river bed changes in the river Rhine

Huthoff, F., van Denderen, P., & Paarlberg, A. - 11/02/2021 - RiverCare
It is important to link cause-and-effect relations between bed response and their dominating triggers. This is particularly important in highly-engineered navigable rivers, where multiple influences from close-by and further away can obscure the dominating causes of local bed level changes, and thereby possibly point in the wrong direction when it comes to sustainable river management practices.
