After this, a minimum depth of 14.5 meter below NAP could be guaranteed for the fairway. Thresholds slit up constantly, leading to continuous dredging to keep them at the desired depth. The maintenance dredging work on the thresholds encompassed an average of 8 to 9 million m3 a year from 1978 to 1989, and approximately 2 million m3 a year on the remaining areas.","EngDescr":null,"OrigAbstract":"De eerste grote verruiming van de Westerschelde begon in 1967 met het verdiepen van de drempel van Bath en eindigde in 1978 toen als laatste de drempel van Hansweert verdiept was (Belmans, 1988). Na deze verdieping kon voor de vaargeul een minimale diepte van 14,5 meter beneden NAP gegarandeerd kon worden. Drempels zanden constant aan en daarom moet er continu gebaggerd worden om ze op de gewenste diepte te houden. De onderhoudsbaggerwerkzaamheden op de drempels bedroegen vanaf 1978 tot 1989 gemiddeld 8 à 9 miljoen m³ per jaar en op de overige gebieden rond 2 miljoen m³ per jaar.","OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":"Dutch","EmbargoDate":null,"OrigDescrLangNL":"Nederlands","OrigLangCode":"nl","OrigLangCodeExtended":"dut","OrigLangID":41,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":null,"AccessConstraints":null,"UDate":"2010-07-19","CDate":"2010-01-14","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-05-30 01:37:59.451226","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":0,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":0,"FreshFlag":0,"BrackishFlag":1,"TerrestrialFlag":0,"StatusID":1,"DasType":"Static graphs","DasTypeID":18,"DasOrigin":null,"Progress":null,"AccessConstraint":null,"AccConstrEN":null,"AccConstrDisplay":null,"License":null,"AccConstrDescription":null,"Lineage":null,"AccConID":null},"dois":null,"spcols":[{"SpColID":52,"SpName":"Methods and techniques"},{"SpColID":27,"SpName":"ScheldeMonitor"}],"keywords":[{"ThesaurusTerm":"ANE, Netherlands, Westerschelde","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, Netherlands, Westerschelde","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Dredging","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_50c7fa97","Description":null,"OrigThesTerm":"Dredging","DutchTerm":"Baggerwerk","URI":"http://aims.fao.org/aos/agrovoc/c_50c7fa97","DasKeywordDescr":null},{"ThesaurusTerm":"Dredging","ThesTypID":2,"ThesType":"CSA Technology Research Database Master Thesaurus","Code":null,"Description":null,"OrigThesTerm":"Dredging","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Dredging","ThesTypID":3,"ThesType":"Transportation Research Thesaurus","Code":"Fcfxeud","Description":null,"OrigThesTerm":"Dredging","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Dredging","ThesTypID":4,"ThesType":"CAB Thesaurus","Code":"40702","Description":null,"OrigThesTerm":"Dredging","DutchTerm":"Baggeren","URI":"https://id.cabi.org/cabt/40702","DasKeywordDescr":null},{"ThesaurusTerm":"Sand","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_6779","Description":null,"OrigThesTerm":"Sand","DutchTerm":"Zand","URI":"http://aims.fao.org/aos/agrovoc/c_6779","DasKeywordDescr":null},{"ThesaurusTerm":"Western Scheldt estuary (The Netherlands)","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"Western Scheldt estuary (The Netherlands)","DutchTerm":null,"URI":null,"DasKeywordDescr":null}],"parents":null,"children":null,"othrel":null,"othrelrev":null,"ownerships":[{"OrderNr":1,"Surname":"Peters","Firstname":"Bianca","Initials":"B.G.T.M.","PerPublicFlag":1,"AdrID":null,"Email":null,"InsPublicFlag":1,"Acronym":null,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"InsOwnerCNT":1,"PersID":13928,"InsID":8730,"FullInstitute":"Ministerie van Infrastructuur en Milieu;
