Such a set-up also matches wav etank conditions used for testing and validation of model structures such as ships in maritime engineering. Note that shorter\, non-breaking and dis persive waves in deeper water are thus damped by wave breaking at the beac h. A suitable coupling point is chosen in sufficiently shallow water\, whe re the two models are coupled by using variational techniques. Numerically \, a space-time variational approach is followed for the potential-flow wa ter waves coupled to a classical finite-volume method for the shallow-wate r model. The entire approach has been validated numerically against bespok e wavetank experiments undertaken at the TU Delft. The main work was perfo rmed by Floriane Gidel [1]\, in collaboration with Tim Bunnik and Geert Ka psenberg (MARIN\, Maritime Research Institute Netherlands)\, Mark Kelmanso n and the speaker (Leeds). \n\n[1] F.
