These include topics such as the prediction of coastal erosion and floo ding\, the design of engineering solutions and the development of nearshor e marine renewable devices and offshore wind turbines. With the aim to inf orm these applications\, this work will present recent findings on the acc urate modelling and understanding of coastal processes.\n\nRather than foc using solely on regular wave patterns\, this work delves into the statisti cal representation of random wave variables\, a crucial aspect often overl ooked in traditional analyses. To achieve this\, an extensive dataset comp rising long random wave simulations was generated at the Hydrodynamics Lab oratory of Imperial College London. By parametrically exploring a broad pa rameter range of incident storm conditions across three distinct planar be ach bathymetric profiles\, we aim to provide comprehensive insights into c oastal wave evolution. High-resolution analysis of water surface elevation s\, covering the entire length of the beach and encompassing over half a m illion waves per location\, was conducted. Additionally\, numerical invest igations employing a phase-resolving\, non-hydrostatic model (SWASH) were performed to validate the findings.\n\nComparative analyses between our da tasets and existing theoretical frameworks shed light on the distribution of wave heights and crest heights. Furthermore\, we investigate the interp lay between nonlinear wave evolution\, wave breaking\, and the underlying topography of the problem. The present work highlights some disparities be tween theory and empirical measurements but also offers valuable physical insights. These insights\, coupled with practical considerations tailored for engineers\, aim to facilitate more accurate and effective coastal engi neering solutions.\n LOCATION:https://researchseminars.org/talk/UEA_mth/6/ END:VEVENT END:VCALENDAR
