Abstract: Favre waves are non-linear, weakly dispersive wave trains in rivers and channels. In nature, they appear when one or more sluice gates of low-head dams are closed or opened for maintenance reasons. Favre waves develop under certain hydraulic conditions characterized by a Froude number between 1 and 1.3. Under these conditions they can travel several kilometers and have amplitudes up to two times higher than the theoretical hydraulic jump (Treske, 1994), leading to flooding risks. The aim of the present work is to contribute to the experimental knowledge and to the numerical modelling of Favre waves by comparing new experiments and simulations in cases close to engineering situations. The simulations are done with a method proposed by the authors in a recent journal paper (Jouy et al., 2024).
