The present paper addresses the prediction of wave breaking from measuredtime-histories of the free surface profile. The Double Fourier velocitypotential model of Baldock and Swan (1994) is used to study timehistoriesobtained in a wave basin that contain large wave events. Themodel can recreate the surface elevation in space using a single timehistoryand the results are used to study geometrical properties of thewaves in the spatial domain. Wave breaking is detected by using the freesurface values of the dynamic breaking criterion proposed by Barthelemyet al. (2018). The evolution of the Bx parameter is obtained from the experimentalmeasurements directly and it is shown to separate steep wavesfrom breaking events.
