Forces on a Vertical Dam due to Solitary Impulse Wave Run-Up and Overtopping

Extreme wave run-up on a vertical cliff

Wave impact and run-up onto vertical obstacles constitutes one of the main phenomena which have to be taken into account in the design of coastal structures. From the linear wave theory we know that the wave height on a vertical wall is twice the incident wave amplitude. Weakly nonlinear theories bring some small corrections to this result. However, in the present study we show that certain sim...

Vulnerability of Buildings on Coastal Dikes due to Wave Overtopping

The vulnerability of buildings on coastal dikes due to overtopping wave impacts is difficult to assess. A method is developed in this paper to quantify the vulnerability of masonry buildings on a coastal dike exposed to wave overtopping. Using previous studies, the accidental loads due to the extreme wave impacts are characterized. Using the approach from Eurocode 6, the strength of masonry bui...

Boussinesq Modelling of Solitary Wave Propagation, Breaking, Runup and Overtopping

A one-dimensional hybrid numerical model is presented of a shallow-water flume with an incorporated piston paddle. The hybrid model is based on the improved Boussinesq equations by Madsen and Sørensen (1992) and the nonlinear shallow water equations. It is suitable for breaking and non-breaking waves and requires only two adjustable parameters: a friction coefficient and a wave breaking paramet...

Numerical Wave Tank Analysis of Wave Run-Up On a Truncated Vertical Cylinder

A new far-field closure condition for a CFD-based numerical wave tank that uses a potential wave solution to overlay the outer computational domain of a CFD solution is described. A prescribed potential wave solution covers the region beyond a diameter more than 10 times of floater footprints. The diffracted waves from the body are absorbed by the ‘potential-attractor’ terms applied in the inte...
