Benthic species as mud patrol ‐ modelled effects of bioturbators and biofilms on large‐scale estuarine mud and morphology

Muriel Z.M. Brückner, Christian Schwarz, Giovanni Coco, Anne Baar, Márcio Boechat Albernaz, Maarten G. Kleinhans - 31/03/2021 - Estuaries shaped by biomorphodynamics, inherited landscape conditions and human interference

Numerical modelling of wave overtopping at dikes using OpenFOAM

Chen, W., Warmink, J. J., van Gent, M. R. A., & Hulscher, S. J. M. H. - 21/03/2021 - All-Risk
A 2D numerical model based on OpenFOAM® is set up in this study for predicting wave overtopping at dikes that have complex configurations with berms and roughness elements.

Risks and management of alien freshwater crayfish species in the Rhine-Meuse river district

Pim Lemmers, Frank P.L. Collas, Ronald Gylstra, Ben H.J.M. Crombaghs, Gerard van der Velde and Rob S.E.W. Leuven* - 17/03/2021

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 berekenen de faalkans van overslag voor dijken met een goede en beschadigde grasmat en laten zien dat beschadigen aan de grasmat, zoals een konijnen hol of een erosie gat, leiden tot een behoorlijke toename van de faalkans.

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.

Innovatieve monitoringstechnieken voor rivierbeheer : verkenning naar de mogelijkheden en de meerwaarde van cameramonitoring

Bart Strijker, Guy Dupuits, Eelco Verschelling, Fedor Baart - 01/03/2021

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
