Title: Water Waves. Applications to their interaction with obstacles and to the impact by extreme meteorological conditions

Abstract:

The classical mathematical description of water wave motion will be presented and two related problems will be addressed through applications in ocean engineering and oceanography. The hydrodynamic forces on offshore structures are of interest to the energy industry.

This problem will be modelled by singular integral equations where the solutions can be efficiently computed by a spectral method. Ocean waves can be modelled and predicted using the linear theory and the wave action balance equation employed by models such as SWAN and SWASH. The impact on the coast, including flooding, caused by extra-tropical cyclones can then be estimated.

These two examples will be presented in the light of recent results.
