Numerical hydrodynamic modelling represents the backbone of modern river design and engineering. My research builds on two-dimensional models, which is a compromise between computational performance and accuracy. The ultimate goal, however, is morphodynamic modelling, which currently provide reliable results only with complementary physical laboratory models.
As long as numerical methods are still struggling with efficient solutions for sediment transport and morphodynamics, these can be well reproduced in physical models. We used physical modelling, for example, to optimize sediment passage in the framework of the restoration of the Drance River (Valais, Switzerland).
