Current patterns are dominated by eddies. Residual currents produce enhanced transverse and axial dispersion by the mechanism of tidal \"random walk\". The axial dispersion coefficient due to residual current eddies is shown to be comparable to the observed long-term value for the seaward section of estuary considered, and is much greater than values which can be attributed to vertical shear in tidal and residual currents, or transverse shear in tidal currents. Transverse mixing due to tidal \"random walk\" is found to be much greater than that which can be attributed to other known mechanisms. Estuarine width is shown to be important in that it limits the size of horizontal eddies, and therefore controls the dispersion for given tidal and residual current speeds.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Residual currents in the Severn Estuary and their effects on dispersion","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":1982,"MonPub":null,"DateUpdate":"2005-09-20","DateCreate":"2005-09-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1982PP25500003","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":76594,"PubliDate":1982,"Pagination":"403-410","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43599,"SerRR":"Oceanologica Acta.
