Transport is in the form of bed load and the rate of transport is proportional to some power of the local current speed. It is assumed that the tidal current is dominated by the M<sub>2</sub> constituent. From the analytical expression it follows that the interactions of M<sub>2</sub> and M<sub>o</sub> (= Eulerian mean current) and of M<sub>2</sub> and any of its even overtides, M<sub>4</sub>, M<sub>8</sub> <i>etc.</i>, constitute the major contribution to the tidally averaged sediment transport. A combination of the M<sub>2</sub> tidal current and a fundamental constituent in the diurnal, semidiurnal or subsequent period bands results in a tidally averaged transport that fluctuates with the corresponding beat frequency. Therefore, for the long-term mean bed-load transport only the contributions of M<sub>2</sub> and M<sub>o</sub> and of M<sub>2</sub> and its even overtides are of interest. Application to the main channel of the Ems estuary showed good agreement with transport pathways derived from the grain-size distribution pattern. The tidally averaged sediment transport is largely the result of the interaction of the M<sub>2</sub> and M<sub>o</sub> tidal current constituents.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Tide-induced residual transport of coarse sediment; application to the Ems estuary","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1993,"MonPub":null,"DateUpdate":"2001-09-14","DateCreate":"2001-08-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1993MK65700001","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16128,"PubliDate":1993,"Pagination":"209-220","XtraPublOfAnaID":null,"ISBN":null,"Volume":"31","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
