Autor: Nils B. Kerpen, Torsten Schlurmann, Alexander Schendel, Jannek Gundlach, Daniel Marquard, Markus Hüpgen

Publikováno v: Frontiers in Marine Science, Vol 7 (2020)

In this study, the wave-induced distribution of 13 microplastic (MP) samples of different size, shape, and density was investigated in a wave flume with a sandy mobile beach bed profile. The particle parameter were chosen based on an occurrence proba

Effect of Variations in Water Level and Wave Steepness on the Robustness of Wave Overtopping Estimation

Autor: Nils B. Kerpen, Karl-Friedrich Daemrich, Oliver Lojek, Torsten Schlurmann

Publikováno v: Journal of Marine Science and Engineering, Vol 8, Iss 2, p 63 (2020)

The wave overtopping discharge at coastal defense structures is directly linked to the freeboard height. By means of physical modelling, experiments on wave overtopping volumes at sloped coastal structures are customarily determined for constant wate

Wave Impact Pressures on Stepped Revetments

Autor: Nils B. Kerpen, Talia Schoonees, Torsten Schlurmann

Publikováno v: Journal of Marine Science and Engineering, Vol 6, Iss 4, p 156 (2018)

The wave impacts on horizontal and vertical step fronts of stepped revetments is investigated by means of hydraulic model tests conducted with wave spectra in a wave flume. Wave impacts on revetments with relative step heights of 0.3 < Hm0/Sh < 3.5 a

Full-scale experimental study on wave reflection and run-up at stepped revetments

Autor: Nils B. Kerpen, Torsten Schlurmann, Talia Schoonees

Publikováno v: Coastal Engineering. 172:104045

Stepped revetments are suitable coastal structures in urban areas as they effectively limit wave overtopping whilst offering recreational benefits. A deeper understanding of wave-structure interactions facilitates optimised stepped revetment designs.
