An iterative methodology is proposed and applied for experimental generation of tsunami-like waves using a piston-type wavemaker with spectral control. Three distinct types of wave interaction with the beach are observed with forming of plunging or collapsing breaking waves. The Lagrangian model demonstrates good agreement with experiments. It proves to be efficient in modelling both wave propagation along the flume and initial stages of strongly non-linear wave interaction with a beach involving plunging breaking. Predictions of wave runup are in agreement with both experimental results and the theoretical runup law. date: 2013-10 official_url: http://dx.doi.org/10.1016/j.coastaleng.2013.05.008 vfaculties: VENG oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_source: WoS-Lite elements_id: 809795 doi: 10.1016/j.coastaleng.2013.05.008 lyricists_name: Buldakov, Eugeny lyricists_id: EBULD04 full_text_status: public publication: Coastal Engineering volume: 80 pagerange: 83 - 94 issn: 0378-3839 citation: Buldakov, E; (2013) Tsunami generation by paddle motion and its interaction with a beach: Lagrangian modelling and experiment.
