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.

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 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.

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.

Scenarios for Controls of River Response to Climate Change in the Lower Rhine River

11/02/2021 - Rivers2Morrow

We discuss the projected changes of the hydrodynamic river controls over the 21st century, and how they can be transformed into suitable boundary conditions for a schematized model. Here we consider the Lower Rhine River, from Bonn (Germany) to Gorinchem (Netherlands).

Compensating human interventions at a river bifurcation

Gensen, M. R. A., Warmink, J. J., Huthoff, F., & Hulscher, S. J. M. H. - 11/02/2021 - All-Risk

Impact of river interventions under a range of discharges and roughness conditions to possibly counteract the feedback mechanism between water levels and discharge at a bifurcating river.
