Er zijn 2 formules bepaald om aan de hand van de stuwstand, het op- en afwaartse &nbsp;waterpeil en debietscoëfficiënten het debiet te bepalen dat over en/of onder de stuw passeert: &nbsp;een overstortformule over de klep (Qklep) en een onderstromingsformule wanneer het water onder &nbsp;het segment stroomt (Qseg). Aan het Hydrologisch Informatiecentrum van het Waterbouwkundig &nbsp;Laboratorium (WL-HIC) werd gevraagd om een debietmeting uit te voeren om de gebruikte formules &nbsp;te controleren en daarbij te adviseren rond de voorgestelde debietscoëfficiënten. Tegelijk werd &nbsp;gevraagd om de inlaat van de vispassage te bemeten en ook de goede werking van de schuif die het &nbsp;toegevoegd debiet in de vispassage regelt te controleren.<br>In rapport WL2025R23_078_1 (Vereecken et al. 2025) werd gefocust op de debieten die over de klep &nbsp;stromen (overstortformule) aangezien de condities tijdens de metingen eind 2024 opwaarts de stuw &nbsp;in de stuwgeul een controle van de onderstromingsformule niet toelieten. Tevens werden tijdens de &nbsp;metingen van 2024 ook de inlaat van de vispassage en het toegevoegd debiet via de regelschuif &nbsp;bemeten en besloten dat beiden goed gedimensioneerd waren.<br>Voorliggend rapport beschrijft de debietmetingen die in het najaar van 2025 en begin 2026 zijn &nbsp;uitgevoerd afwaarts de stuw bij hogere afvoeren waarbij ook water onder het segment stroomt. &nbsp;Voor een goede interpretatie van de metingen zijn de beste inschattingen van het debiet doorheen de &nbsp;vispassage en het toegevoegd debiet bepaald, alsmede het debiet dat afwaarts de stuw via de &nbsp;Gaverbeek wordt toegevoegd","BibLvlCode":"MS","StandardTitle":"Debietmeting in kader van afijking gerenoveerde stuw Sint-Baafs-Vijve – addendum – ijking bij hogere debieten","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2026-09-14 16:03:16.655947","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":"IJking","OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2026,"DateUpdate":"2026-09-14","DateCreate":"2026-09-09","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":0,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":447822,"ISBN":null,"PubliDate":2026,"IssueDate":null,"Volume":"23_078_2","Issue":null,"Pagination":"VI, 12","Place":"Antwerpen","Edition":"Versie 4.0","BRefXtra":null,"BRefXtraRR":null,"SerID":24938,"SerRR":"WL Rapporten.
