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.

Flow Structure at the Pannerdense Kop Bifurcation

11/02/2021 - Rivers2Morrow
Flow structure provides useful information regarding these by detailing the threedimensional features of flow. This abstract mainly focuses on some of the observations from the ADCP surveys performed between November 2019 and February 2020 at the Pannerdense Kop

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.

Future sediment budget and distribution for the Rhine-Meuse delta

11/02/2021 - Rivers2Morrow
The Rhine-Meuse delta in the Netherlands has a negative sediment budget, i.e. it annually looses sediment. In this research, we construct a sediment budget for two future scenarios 2050 and 2085 which incorporate both socio-economic change and climate scenarios for the region
