Abstract: Highlights•Development of first free and fully flexible adjoint hydro-morphodynamic framework.•Verification of adjoint capabilities using dual-twin experiments.•Application of adjoint methods to analyse sensitivity to spatially-varying parameters.•Use of adjoint methods to calibrate for several uncertain parameters in an experiment.•Inversion of a tsunami-like wave using final sediment deposits from experimental data.
