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

Future sediment budget and distribution for the Rhine-Meuse delta
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

Towards a model for river dune dynamics under high and low discharges
The interplay of bedform dynamics, especially river dunes, and extreme flow conditions results in multiple challenges in river management. Decreasing this uncertainty results in more certain flood levels and therefore increases water safety.

A sediment budget for the Rhine-Meuse estuary: importance of dredging and the North Sea sediment flux
In this research, a sediment budget is created for the Rhine-Meuse Estuary (RME) located in the West of the Netherlands for the period 2000- 2018. This budget is also juxtaposed with previous budgets for the area to see how the current sediment budget compares

Superimposed bedforms in the Rhine-Meuse delta
This research aims to elucidate the role of superimposed bedforms in rivers and to determine whether superimposed bedforms contribute to the transport of bed sediment and how they interact with primary dunes.

RiverLab – the numerical experimental facility for river research
The RiverLab is set up as the numerical experimental facility to work together on software and models for research related to river behavior and dynamics. It is not just a model development platform - It’s a community.

Bed level change in the upper Rhine Delta since 1926 and rough extrapolation to 2050
This study constitutes a first step into predicting the long term morphodynamic response of the Upper Rhine- Delta to climate change. The aim is to get deeper insight into past bed level trends and explore options for data-based extrapolation.

A regularization strategy for the two-dimensional active layer model
We propose a different regularization strategy that guarantees that the two-dimensional active layer model is well-posed. We implement the two-dimensional regularization strategy in Delft30-FM and apply it to an idealized case and a field case.

Room for living rivers: effect of large-scale river widening on soil erosion Waal
In dit rapport is gekeken of rivierverruiming een bijdrage kan leveren aan het stoppen of afremmen van de bodemerosie. Met “verkennende berekeningen” is de invloed van (combinaties van) voorgestelde maatregelen op het sedimenttransport en lange termijn bodemontwikkeling van de Waal in kaart gebracht. Ook is gekeken wat naast rivierverruiming nodig is aan suppleties om de bodemerosie op de Waal geheel te kunnen stoppen en in hoeverre door verruiming de benodigde suppletievolumes afnemen.
