This experimental study focuses the inﬂuence of bed material mobility and initial downstream water level on maximum waterlevel and time to peak of dam-break waves. It covers horizontal bed conditions on ﬁxed bed, sand bed, and pumice bed. Results includewater surface level time evolution, maxima wave levels and time to peak. The inﬂuence of bed material mobility and downstream waterlevel was identiﬁed and characterized, stressing the importance of using mathematical models with appropriate sediment transportformulations instead of purely hydrodynamic models to simulate dam-break waves on mobile bed channels.
