Wave Run-Ups and Overtopping Affected by Oblique Wave Approaches and Currents

Abstract

To quantify the effect of a current on the height of a wave’s run-up and overtopping combined with an oblique wave approach, the “FlowDike” hydraulic research project was carried out. Tests were performed on two dike slopes of 1:3 and 1:6. Waves were generated across (perpendicular to) the physical model and also inclined in-plane to the stream axis. Oblique waves were generated both towards and along the flow’s direction. The effect of the current and of the wave direction on the height of the wave run-up and amount of the wave overtopping was expressed by means of a combined correction factor for the wave’s inclination and flow velocity. The results of the research confirmed that the flow velocity had only a small effect.

Spectral analysis of oscillatory wind wave parameters in fetch-limited deep-water conditions at a small reservoir and their prediction: Case Study of the Hulín Reservoir in the Czech Republic

“…When certain conditions are met, it can be assumed that the relationships between wave parameters can still be sufficiently plausibly described by linear wave propagation theory. In the last decade in the Czech Republic, numerous types of research have been performed on closed reservoirs, and draft protective measures have been applied to banks (Kotaška, 2019;Pelikán and Marková, 2013;Pelikán and Šlezingr, 2015;Pelikán and Koutný, 2016;Říha and Špano, 2012;Špano, 2019;Špano and Duchan, 2021;Špano et al 2022).…”
