Accuracy of Numerical Morphological Models based on Simplified Hydrodynamics

Sustainable river management often requires long-term morphological simulations. As the future is unknown, uncertainty needs to be accounted for, which may require probabilistic simulations covering a large parameter domain. Even for one-dimensional models, simulation times can be long. One of the acceleration strategies is simplification of...

Accuracy Assessment of Numerical Morphological Models Based on Reduced Saint-Venant Equations

Can linear stability analyses predict the development of riverbed waves with lengths much larger than the water depth?

Sustainable river management can be supported by models predicting long-term morphological developments. Even for one-dimensional morphological models, run times can be up to several days for simulations over multiple decades. Alternatively, analytical tools yield metrics that allow estimation of migration celerity and damping of bed waves,...

The 2021 flood event in the Dutch Meuse and tributaries from a hydraulic and morphological perspective

In July of 2021, large areas in the catchment of the Meuse River in Belgium, the Netherlands and Germany were affected by extreme rainfall and floods. This paper presents the hydraulic and morphological data that were collected during and after the flood. The data were analysed to understand the hydraulic and morphological functioning of the...

Efficient long-term one-dimensional morphodynamic modelling in alluvial rivers using simplified models – theory and validation

A stochastic model approach for optimisation of lowland river restoration works

Over the course of centuries, river systems have been heavily trained for the purpose of safe discharge of water, sediment and ice, and improves navigation. Traditionally, dikes are used to be reinforced and heightened to protect countries from ever higher flood levels. Other types of solutions than technical engineering solutions, such as...

Evaluation of design hydrograph methods and probabilistic methods for estimating design water levels on the river Meuse

Design water levels are needed for the design of flood defences along the Dutch river Meuse. Current practise is that these water levels are determined by hydrodynamic simulation of a standard design hydrograph at the upstream gauging station Borgharen. The peak discharge of this synthetic hydrograph is based on a frequency analysis of the 100...
