Transient waves generated by a box falling into water are analytically and experimentally investigated (Scott Russell wave generator). Within the frame of linear theory, a new analytical solution for the leading wave is proposed. It is shown that both the impulse pressure of the box's impact on the free surface and the velocity field generated during the underwater phase (wave generator type boundary condition) have to be taken into account when predicting wave amplitude and period. The analytical solution, in satisfactory agreement with experiments performed in a two-dimensional flume, can be used for validating numerical models and for estimating the order of magnitude of landslide-generated waves.

Abstract
Transient waves generated by a box falling into water are analytically and experimentally investigated (Scott Russell wave generator). Within the frame of linear theory, a new analytical solution for the leading wave is proposed. It is shown that both the impulse pressure of the box's impact on the free surface and the velocity field generated during the underwater phase (wave generator type boundary condition) have to be taken into account when predicting wave amplitude and period. The analytical solution, in satisfactory agreement with experiments performed in a two-dimensional flume, can be used for validating numerical models and for estimating the order of magnitude of landslide-generated waves.| File | Dimensione | Formato | |
