Eames","doi":"10.1680/jwarm.2019.172.1.37","DOIUrl":"https://doi.org/10.1680/jwarm.2019.172.1.37","url":null,"abstract":"The dynamics of waves and their interaction with a beach depends on whether the leading wave component is elevated or depressed. These differences are explained in this paper using a hydraulic model and the principle of conservation of impulse. Laboratory experiments of depression waves, conducted using a novel wavemaker, are compared with model predictions. Over a sloping beach, these waves have a nearly constant V-shaped depression trailed by a growing Λ-shaped positive wave. The shoreline recedes over a significant distance, caused by shoreward water being drawn into the V-shaped depression. When the trailing Λ-shaped positive wave breaks, an energetic hydraulic bore develops and moves up the beach. The hydraulic model leads to general formulae for wave slopes, draw-down and run-up. The run-up of negative waves can be larger or smaller than that of positive waves, depending on the wave amplitude and beach parameters. The predictions are compared with results from photographs of depression waves taken during the 2004 Sumatra tsunami. Similar phenomena occurred in Japan in 2011. By incorporating up/down amplitude data in new tsunami warning systems, the properties of tsunamis on beaches could be estimated in real time using the present work, thus improving emergency response strategies. In future, the damage associated with tsunami waves, depending on coastal parameters, could increase with rising sea levels, erosion and destruction of coral reefs, and the loss of Arctic sea-ice.","PeriodicalId":54061,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Engineering and Computational Mechanics","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90501894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
