Such a set-up also matches wavetank c onditions used for testing and validation of model structures such as ship s in maritime engineering. Note that shorter\, non-breaking and dispersive waves in deeper water are thus damped by wave breaking at the beach. A su itable coupling point is chosen in sufficiently shallow water\, where the two models are coupled by using variational techniques. Numerically\, a sp ace-time variational approach is followed for the potential-flow water wav es coupled to a classical finite-volume method for the shallow-water model . The entire approach has been validated numerically against bespoke wavet ank experiments undertaken at the TU Delft. The main work was performed by Floriane Gidel [1]\, in collaboration with Tim Bunnik and Geert Kapsenber g (MARIN\, Maritime Research Institute Netherlands)\, Mark Kelmanson and t he speaker (Leeds). \n\n[1] F.
