In the context of fish migration between the Scheldt and the Reduced Tidal Areas, in 2015, during the annual 13-hour measurement in the GOG/GGG Bergenmeersen, WL measured the slope of one non-return valve in addition to the incoming and outgoing flow. The measurement of the non-return valve and the analysis were carried out under project 15_034. The measurement of flow rate and valve angle were successful. The analysis provided important insights into the fish migratory capacity of the non-return valve. The measured levels upstream and downstream of the structure were less reliable. During the 13-hour measurement planned on 22/09/2016 at Bergenmeersen, the up- and downstream gauges will be read telemetrically and the outgoing flow rate will be measured by means of an adcp device placed in a shaft. In addition, the INBO will also conduct a test with a cap by and fish trap around the same period. For these reasons, it is considered opportune to measure the slope of the check valve again in 2016. This opinion concerns the measurement of the check valve and analysis of the results analogously as carried out in 2015.
","AbstractOtherLang":"In kader van de vismigratie tussen de Schelde en de Gereduceerde Getijdegebieden heeft WL in 2015, tijdens de jaarlijkse 13 uurs meting in het GOG/GGG Bergenmeersen, naast het in- en uitgaande debiet ook de helling van één terugslagklep opgemeten. Het opmeten van de terugslagklep en de analyse zijn uitgevoerd onder project 15_034. De meting van het debiet en de klephoek zijn goed gelukt. De analyse gaf belangrijke inzichten in de vis migreerbaarheid van de terugslagklep. De opgemeten peilen op- en afwaarts van de constructie waren minder betrouwbaar. \r\n\r\nTijdens de op 22/09/2016 geplande 13-uurs meting te Bergenmeersen worden de peilen op- en afwaarts telemetrisch ingelezen en zal het uitgaande debiet opgemeten worden door middel van een in een koker geplaatst adcp toestel. Bijkomend zal rond dezelfde periode ook het INBO een proef uitvoeren met een pet door en vissen afvangen. Omwille van deze redenen wordt het opportuun geacht om in 2016 opnieuw de helling van de terugslagklep op te meten. \r\n\r\nDit advies betreft de opmeting van de terugslagklep en de analyse van de resultaten analoog zoals uitgevoerd in 2015.","DateLastModified":{"date":"2025-03-31 14:21:54.831934","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":2016,"EndYear":2019,"BMonth":9,"EMonth":1,"BeginMonth":"September","EndMonth":"January","OrigTitleLangCode":null,"OrigTitleLangID":null,"OrigTitleLangNL":null,"OrigTitleLang":null,"OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":1,"ND":"2019-01-11","UD":"2025-03-31","DMPFlag":0,"Budget":1,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":"WL","ProPartID":16520,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Flemish Government; Mobility and Public Works; Flemish Ministry of Mobility and Public Works; Department of Mobility and Public Works; Flanders Hydraulics","Line1":"Berchemlei 115","Line2":"2140 Antwerpen (Borgerhout)","Line3":null,"Line4":null,"InsID":116,"FullStandardName":"Vlaamse overheid; Beleidsdomein Mobiliteit en Openbare Werken; Vlaams Ministerie Mobiliteit en Openbare Werken; Departement Mobiliteit en Openbare Werken; Waterbouwkundig Laboratorium","Role":"Executant","RoleID":31,"EncAddress":"Berchemlei 115, 2140 Antwerpen (Borgerhout), Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[{"Surname":"Vercruysse","Firstname":"Jeroen","Initials":"J.B.","LeaderFlag":1,"PersID":14808,"Role":null,"RoleID":null,"PastInstitute":0,"BeginDay":15,"BeginMonth":3,"BeginYear":2007,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Visser","Firstname":"Klaas Pieter","Initials":"K.P.","LeaderFlag":0,"PersID":26457,"Role":"Observer","RoleID":16,"PastInstitute":0,"BeginDay":3,"BeginMonth":9,"BeginYear":2012,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Das","Firstname":"Sam","Initials":"S.","LeaderFlag":0,"PersID":11347,"Role":"Partner","RoleID":17,"PastInstitute":0,"BeginDay":1,"BeginMonth":8,"BeginYear":2005,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Smolders","Firstname":"Sven","Initials":"S.","LeaderFlag":0,"PersID":20633,"Role":null,"RoleID":null,"PastInstitute":0,"BeginDay":4,"BeginMonth":4,"BeginYear":2014,"EndDay":null,"EndMonth":null,"EndYear":null},{"Surname":"Coen","Firstname":"Leen","Initials":"L.","LeaderFlag":0,"PersID":16217,"Role":null,"RoleID":null,"PastInstitute":1,"BeginDay":1,"BeginMonth":8,"BeginYear":2014,"EndDay":23,"EndMonth":12,"EndYear":2023},{"Surname":"Henderick","Firstname":"Andy","Initials":"A.","LeaderFlag":0,"PersID":18733,"Role":"Data collector","RoleID":18,"PastInstitute":0,"BeginDay":12,"BeginMonth":1,"BeginYear":2007,"EndDay":null,"EndMonth":null,"EndYear":null}],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null},{"instituterec":{"Acronym":null,"ProPartID":16522,"PublicFlag":1,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"Line1":"Havenstraat 44","Line2":"3500 Hasselt","Line3":null,"Line4":null,"InsID":14126,"FullStandardName":"De Vlaamse Waterweg","Role":"Proposer","RoleID":32,"EncAddress":"Havenstraat 44, 3500 Hasselt, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null}],"refs":[{"BRefID":304386,"AnaPub":null,"MonPub":2018,"RefStringPartII":".
