Abstract:

A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal structures. Shoaling rates and amplitudes are calculated during wave propagation and transformation. Comparison is made with low-order theory and with experiments. Wave impact and breaking on coastal structures are calculated for waves entering the shallower water region. Velocities, impact pressures and forces are calculated and compared to experimental results.
