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.

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.

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

The evolution of primary dunes during low flows on the Waal river

11/02/2021 - Rivers2Morrow

In this study, we investigate the dune evolution in a stretch of 2 km Waal iver, the Netherlands, between the cities of Tiel and St. Andries, focusing on the low water period of 2018. The bed elevation profiles are based on Multibeam Echo Sounding (MBES) measurements of the fairway, measured on average once per two weeks.

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).
