In this webinar, we will show the processes of making a morphological
model of the Rhine Branches in the Netherlands, from the early
discussions on the conceptual setup, through the model construction,
calibration, until the utilisation in projects and case studies.
The Rhine River is considered the backbone of the Northwest European
waterways network. All efforts are made to ensure the navigability of
the river all year round. Due to the morphological behavior of the
river, navigation is subject to hindrance in some locations and
frequent maintenance is being carried out. Morphological changes of
the river are predicted to increase the number of nautical bottlenecks
in the coming years.
Accordingly, a decision
was then taken to create a morphological model that covers the entire
Rhine branches in the Netherlands. The model aims to provide a tool
for river managers, which enables assessment of the morphological
response of the river to different maintenance plans as well as
changes in dredging strategies for a sustainable navigation channel.
Subsequently, a detailed numerical quasi-3D morphological model has
been set up. The model covers, nearly, the entire Rhine system in the
Netherlands, including the branches Bovenrijn, Waal, Pannerdensch
Kanaal, IJssel, Nederrijn, and the Merwedes. The model is used to
analyse the long-term large-scale evolution of the system
incorporating complex time-dependent multi-dimensional phenomena, such
as curvature-induced point bar and pool patterns in bends, as well as
the intermediate-scale (seasonal) variations, which instigate dredging
activities. Several state-of-the-art modelling elements have been
developed and utilised to construct and efficiently run this model;
particularly, a simulation management tool and a sophisticated
In this webinar, we will show the steps from the early stages until
making an operational model (Delft3D
4 Suite) and utilizing it in practice. Furthermore, we will give
an outlook for the next generation operational model using Delft3D
Flexible Mesh Suite (Delft3D FM).
Panel of experts
During the webinar, we had a panel of experts available to answer
questions received via text. After the webinar presentation, there
was an opportunity to ask verbal questions to the presenters.
