To investigate the influence of breaking logs on flowpatterns and energy dissipation in the lock chamber, a dedicated (generic) physical model was built, consisting of one circular opening in a lock gate sealed by a vertical lift valve. Both configurations without and with breaking logs, having a square cross-section, were tested. The configurations with breaking logs differ with respect to the spacing and the number of the breaking logs. First, the influence of the breaking logs and the associated blockage of the opening by the breaking logs onto the discharge coefficient of the opening was assessed. The velocity measurements and the visualisation of the flow pattern revealed the spreading of the jet and the corresponding velocity decay at short distances downstream of the gate opening. Also an asymmetrical behaviour of the jet and backflow effects were noticed, due to the dimensions and downstream boundary conditions of the model.","AbstractOtherLang":null,"BibLvlCode":"M","StandardTitle":"Experimental investigation of the influence of breaking logs on the flow patterns induced by lock filling with gate openings [PRESENTATION]","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:43:10.835353","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2016,"DateUpdate":"2017-01-16","DateCreate":"2017-01-16","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":0,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":282656,"ISBN":null,"PubliDate":2016,"IssueDate":null,"Volume":null,"Issue":null,"Pagination":"27 slides","Place":"Antwerp","Edition":"Presented on the 4th IAHR Europe Congress, Liège, Belgium, 27-29 July 2016","BRefXtra":null,"BRefXtraRR":null,"SerID":null,"SerRR":null,"Ser2BRefID":null,"Ser2RR":null,"StandardTitleSer":null,"ISSN":null,"AbbrevSer":null,"Degree":null,"ThesisID":null,"InsID":null,"Acronym":null,"FullStandardName":null,"ToPubliDate":null,"SerNotes":null,"eISBN":null,"Pages":null},"serrec":null,"relations":null,"relationsRev":null,"addrec":null,"othpubs":null,"ownerships":null,"authors":[{"AutName":"Verelst","Firstname":"Kristof","Initials":"K.","Affiliation":"Flanders Hydraulics Research","Discriminator":null,"CorporateFlag":0,"BEntID":274674,"AutID":144372,"OrderNr":1,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":"0000-0002-3926-8421","PersID":3358,"InsID":null},{"AutName":"Vercruysse","Firstname":"Jeroen B.","Initials":"J.B.","Affiliation":null,"Discriminator":null,"CorporateFlag":0,"BEntID":274674,"AutID":73587,"OrderNr":2,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":"0009-0002-1134-4549","PersID":14808,"InsID":null},{"AutName":"Ramos","Firstname":"Pedro","Initials":"P.X.","Affiliation":null,"Discriminator":null,"CorporateFlag":0,"BEntID":274674,"AutID":213468,"OrderNr":3,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":null,"ORCID":null,"PersID":null,"InsID":null},{"AutName":"De Mulder","Firstname":"Tom","Initials":"T.","Affiliation":"Dept. of Civil Engineering, Ghent Univ., Hydraulics Laboratory","Discriminator":null,"CorporateFlag":0,"BEntID":274674,"AutID":220086,"OrderNr":4,"DegrID":null,"EditorFlag":0,"CorrespFlag":0,"IllustratorFlag":0,"ReviserFlag":0,"TranslatorFlag":0,"InsAcronym":null,"InsFSN":"Universiteit Gent;
