An Eulerian model was employed to represent the fluid and the sediment phases. The subgrid-scale fluid stresses were modeled with the Smagorinsky model, whereas subgrid-scale sediment fluxes were based on a gradient approach. To avoid tuning constants, a dynamic procedure was applied. A two-way coupling between sediment and fluid improved the computational description of sediment transport. Sediment concentration profiles and the statistics of sediment fluxes are presented and compared with the Rouse profile and the RANS solution. The results obtained agree well with the theory and with measurements. The LES results also indicate that the assumption of a constant Schmidt number, as is mostly assumed in RANS simulations is erroneous.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Large eddy simulation of sediment transport in open-channel flow","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:32:16.125655","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"LES; open channel; RANS; rouse profile; sedimentation; settling;suspension","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2022-07-12","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000267615700001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/00221686.2009.9522000"},"refs":null,"anarec":{"AnaID":257963,"PubliDate":2009,"Pagination":"291-298","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43069,"SerRR":"Journal of Hydraulic Research = Journal de Recherches hydrauliques.
