{"projectrec":{"ProID":1734,"StandardTitle":"Siltation in the entrance channel to the Berendrechtsluis","OrigTitle":"Aanslibbing in de toegangsgeul van de Berendrechtsluis","Acronym":null,"AbstractEnglish":"Before the Berendrecht lock (new entrance to the Port of Antwerp) was opened, a large scale in situ measurement campaign was organised to measure the siltation rate in the access channel in the\r\nabsence of traffic. The main goals of the measuring programme were:\r\n<ul>\r\n<li>define the different components of the waterflow (tidal variations, vortices, density currents).\r\n<li>evaluate the silt entrainment towards the new lock\r\n<li>evaluate the siltation and consolidation rate in the new entrance channel\r\n<li>define the characteristics of the settled mud.\r\n</ul>\r\nTo meet these requirements within the preset budgetary limits the following major measurements were executed:\r\n<ul>\r\n<li>detailed in situ measurements of velocities (magnitude and direction), temperature, salinity, turbidity and sand content over the complete water depth and a whole tidal cycle (13. hours) from 4 survey vessels,\r\n<li>two campaigns of velocity measurements with floaters: both surface floaters and deep-floaters were used,\r\n<li>during a complete neap- springtide cycle velocity, temperature and salinity were measured in 4 submerged self-recording stations.\r\n<li>in situ density measurement and sampling of the silt with three different techniques (radioactive density probe and 2 different samplers)\r\n<li>regular bathymetric surveys of the whole area with particular interest to the infill rate in a newly created silt trap.\r\n</ul>\r\nThe overall measuring campaign was performed in cooperation with the measuring department of the client and led to a better insight into the different phenomena which influence the siltation and water exchange rates. The measuring reports can be used as a calibration base for the future modelling efforts in the area.","AbstractOtherLang":"Voor de inwerkingstreding van de Berendrechtsluis, werd een grootschalige meetcampagne georganiseerd om de aanslibbing in de toegangsgeul te meten bij afwezigheid van scheepsverkeer.De belangrijkste objectieven van de meetcampagne waren:\r\n<ul>\r\n<li>definiëren van de verschillende componenten van de waterstroom (getijvariaties, draaikolken, dichtheidsstromingen)\r\n<li>evalueren van de slibaanvoer naar de nieuwe sluis\r\n<li>evalueren van aanslibbing in de nieuwe toegangsgeul\r\n<li>definiëren van de kenmerken van het gesedimenteerde slib\r\n</ul>\r\nOm de vereisten binnen het voorgestelde budget te vervullen, werden volgende grote metingen uitgevoerd:\r\n<ul>\r\n<li>gedetailleerde in situ metingen van snelheden (grootte en richting), temperatuur, saliniteit, turbiditeit en zandgehalte in de volledige waterkolom en gedurende een volledige tijcyclus (13 uur) vanop 4 onderzoeksschepen,\r\n<li>twee campagnes van snelheidsmetingen met floaters: zowel oppervlakte floaters als diepte floaters werden gebruikt,\r\n<li>gedurende een volledige doodtij-springtij cyclus werden snelheid, temperatuur en saliniteit gemeten in 4 ondergedompelde zelfopnemende stations,\r\n<li>in situ dichtheidsmetingen en bemonstering van slib met drie verschillende technieken (radioactieve dichtheidssonde en 2 verschillende samplers),\r\n<li>geregelde bathymetrische metingen van het hele gebied met speciale aandacht voor de opvulsnelheid van een nieuw gecreëerde slibval.\r\n</ul>\r\nDe meetcampagne is uitgevoerd in samenwerking met het meetdepartement van de klant en leidde tot een beter inzicht de verschillende fenomenen die aanslibbing beïnvloeden. De meetrapporten kunnen gebruikt worden als calibratie voor toekomstige modelleringsinspanningen in het gebied.","DateLastModified":{"date":"2024-05-06 10:25:46.257000","timezone_type":1,"timezone":"+00:00"},"ParentProID":null,"BeginYear":1989,"EndYear":1990,"BMonth":null,"EMonth":null,"BeginMonth":null,"EndMonth":null,"OrigTitleLangCode":"nl","OrigTitleLangID":41,"OrigTitleLangNL":"Nederlands","OrigTitleLang":"Dutch","OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":1,"ND":"2006-01-27","UD":"2006-08-24","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":"IMDC","ProPartID":6994,"PublicFlag":1,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"Line1":"Van Immerseelstraat 66","Line2":"2018 Antwerpen","Line3":null,"Line4":null,"InsID":777,"FullStandardName":"International Marine & Dredging Consultants NV","Role":"Executant","RoleID":31,"EncAddress":"Van Immerseelstraat 66, 2018 Antwerpen, 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":null,"urls":[{"URL":"www.imdc.be/pdf/FI93003.pdf","externalID":null,"URLTypeCode":null,"URLType":null,"URLTypID":null}],"thesterms":[{"ThesaurusTerm":"Dredging","ThestID":2470,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Dredging","DutchTerm":"Baggerwerk","Code":"c_50c7fa97"},{"ThesaurusTerm":"Hydrodynamics","ThestID":4095,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Hydrodynamics","DutchTerm":"Hydrodynamica","Code":"c_3723"},{"ThesaurusTerm":"Sediment flow","ThestID":7369,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Sediment flow","DutchTerm":"Sedimentstroom","Code":null},{"ThesaurusTerm":"Sediment transport","ThestID":7391,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Sediment transport","DutchTerm":"Sedimenttransport","Code":"c_d1a88f2d"},{"ThesaurusTerm":"Shipping","ThestID":7610,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Shipping","DutchTerm":"Scheepvaart","Code":null}],"taxterms":null,"geoterms":[{"GeoTerm":"Berendrecht Lock","GeoObjectID":8834,"OrigGeoTerm":"Berendrecht Lock","DutchTerm":"Berendrechtsluis"}],"funderids":null,"othtermsFRIS":null,"pictures":[],"spcols":[{"SpColID":27,"SpName":"ScheldeMonitor"},{"SpColID":43,"SpName":"Shipping"},{"SpColID":44,"SpName":"Shipping: Fairway"}],"resmessage":"","complete":1}
