Deze drempel wordt gekenmerkt door een sterke sedimentatie ter hoogte van de groene &nbsp;boeienzijde, aan de oostrand van de platen van Ossenisse.<br>Binnen deze studie werd de waterbeweging en het sedimenttransport ter hoogte van de Drempel van &nbsp;Hansweert in beeld gebracht over de periode 1999 – 2025 met behulp van het SCALDIS model (Telemac3D). &nbsp;In het interessegebied van de studie werd het rekenrooster lokaal verfijnd. Per stap van 5 jaar werd een &nbsp;nieuwe bathymetrie geïnterpoleerd op het verfijnde rekenrooster en werden hydrodynamica en &nbsp;sedimenttransport doorgerekend.<br>Morfologische analyse van de verzamelde topo-bathymetriën toont hoe de bocht tussen de Overloop van &nbsp;Hansweert en de Drempel van Hansweert verbreedt. Tegelijkertijd erodeert de ondiepe zone langs het &nbsp;noordelijke en oostelijke deel van de Platen van Ossenisse. Tussen de Platen van Ossenisse en de Drempel &nbsp;van Hansweert ontstaat een nieuwe ondiepte. Deze nieuwe ondiepte en de Platen van Ossenisse worden &nbsp;gescheiden door een geul, die eb-gedomineerd is.<br>Vanaf 2009 neemt de transportcapaciteit aan de buitenzijde van de bocht van Hansweert stelselmatig toe, &nbsp;terwijl ze aan de binnenzijde van de bocht afneemt. Dit is in overeenstemming met de waargenomen &nbsp;morfologische veranderingen (verbreding van de radius van de bocht). De opeenvolgende simulaties tonen &nbsp;hoe de noordelijke en noordoostelijker rand van de Platen van Ossenisse steeds gekenmerkt worden door &nbsp;een toename van de sedimenttransportcapaciteit. Dit patroon is in overeenstemming met de waargenomen &nbsp;terugschrijding van de plaatrand.","BibLvlCode":"MS","StandardTitle":"Modellering van de waterbeweging en het sedimenttransport ter hoogte van de drempel van Hansweert in de voorbije 20 jaar: deelrapport 1","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2026-06-02 01:38:18.570238","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2026,"DateUpdate":"2026-03-24","DateCreate":"2026-03-23","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":438328,"ISBN":null,"PubliDate":2026,"IssueDate":null,"Volume":"25_086_1","Issue":null,"Pagination":"VI, 52 + 8 p. bijl.","Place":"Antwerpen","Edition":"Versie 4.0","BRefXtra":null,"BRefXtraRR":null,"SerID":24938,"SerRR":"WL Rapporten.
