These accessories are meant to enhance the fish attraction performance of the fish passage attached to the lock‐weir complex in Denderleeuw. Previous studies performed by Badano et al. (2019) for the fish passage in Denderleeuw show favorable currents going through the entrance of the fishpass, and overall flow velocities somewhat below the upper threshold defined by the designer. However, studies conducted here show increased flow bulking and aeration downstream of the weir, plus diminished flow attraction due to the sheer difference in specific forces between the flow exiting the fish passage and the flow produced by the weirs. The present results differ from previous studies, and may lead to different assessments. Therefore, the present work attempts to provide further explanation to the aforementioned phenomena and to critically assess the differences between the previous and the present study.</span>","AbstractOtherLang":null,"BibLvlCode":"MS","StandardTitle":"Numerical study of fish passage entrances annex to Denderleeuw's weir‐lock complex: preliminary assessment of flow attraction performance and revision of previous studies","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-19 01:39:16.211860","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"CFD","OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2025,"DateUpdate":"2025-05-19","DateCreate":"2025-05-12","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":0,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":407941,"ISBN":null,"PubliDate":2025,"IssueDate":null,"Volume":"18_135_1","Issue":null,"Pagination":"IX, 31 + 25 p. bijl.","Place":"Antwerp","Edition":"Version 3.0","BRefXtra":null,"BRefXtraRR":null,"SerID":362151,"SerRR":"FH reports.
