{"projectrec":{"ProID":1785,"StandardTitle":"Modelling of toxic pollutants in an estuarine environment","OrigTitle":"Modelleren van toxische polluenten in een estuarien milieu","Acronym":null,"AbstractEnglish":"A numerical model is presented for simulating the transport of toxic pollutants in rivers, estuaries and seas. The numerical model is based on a finite volume approach and consists of different sub models:\r\n<ul>\r\n<li>A hydrodynamic module for describing river water flow, tidal flows, sea currents, etc.; \r\n<li>A module for simulating the transport of dissolved chemicals and suspended particles, including dispersive mixing due to turbulence; \u00b7 A module for sediment transport, incorporating erosion and resuspension processes; \r\n<li>A module for simulating the transport of sorbing toxic pollutants, using simulation results and information obtained with previous modules. \r\n<\/ul>\r\nThe model is applied to the river Schelde (Belgium), the Schelde estuary (The Netherlands), and the sea along the Belgian coast. Simulation results are presented for several heavy metals and organic micro pollutants, as PCBs, proving the importance of particulate matter. In particular, it is shown that sorbing chemicals tend to accumulate in the estuarine sediments, while only little amounts are reaching the sea. In addition, it is found that the mobility of heavy metals is strongly influenced by salinity, and that the mobility of organic pollutants depends upon complexation with dissolved organic matter.","AbstractOtherLang":null,"DateLastModified":{"date":"2025-07-02 08:33:20.809226","timezone_type":1,"timezone":"+02:00"},"ParentProID":null,"BeginYear":1994,"EndYear":1998,"BMonth":null,"EMonth":null,"BeginMonth":null,"EndMonth":null,"OrigTitleLangCode":"nl","OrigTitleLangID":41,"OrigTitleLangNL":"Nederlands","OrigTitleLang":"Dutch","OtherAbstractLangCode":null,"OtherAbstractLangID":null,"OtherAbstractLang":null,"OtherAbstractLangNL":null,"Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":1,"ND":"2006-06-08","UD":"2006-08-25","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":"HYDR","ProPartID":7250,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Vrije Universiteit Brussel; Faculty of Engineering; Department of Hydrology and Hydraulic Engineering","Line1":"Pleinlaan 2","Line2":"1050 Brussel","Line3":null,"Line4":null,"InsID":790,"FullStandardName":"Vrije Universiteit Brussel; Faculteit Toegepaste Wetenschappen; Vakgroep Hydrologie en Waterbouwkunde","Role":null,"RoleID":null,"EncAddress":"Pleinlaan 2, 1050 Brussel, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[{"Surname":"Mwanuzi","Firstname":null,"Initials":"F.","LeaderFlag":0,"PersID":11750,"Role":null,"RoleID":null,"PastInstitute":1,"BeginDay":null,"BeginMonth":null,"BeginYear":null,"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}],"refs":null,"urls":null,"thesterms":[{"ThesaurusTerm":"ANE, Netherlands, Westerschelde","ThestID":182103,"ThesTypID":34,"ThesType":"ASFA Geoterms","OrigThesTerm":"ANE, Netherlands, Westerschelde","DutchTerm":null,"Code":null},{"ThesaurusTerm":"Ecotoxicology","ThestID":9505,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Ecotoxicology","DutchTerm":"Ecotoxicologie","Code":"c_35788"},{"ThesaurusTerm":"Hydrodynamics","ThestID":4095,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Hydrodynamics","DutchTerm":"Hydrodynamica","Code":"c_3723"},{"ThesaurusTerm":"Modelling","ThestID":5269,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Modelling","DutchTerm":"Modellering","Code":"c_230ab86c"},{"ThesaurusTerm":"PCB","ThestID":6047,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"PCB","DutchTerm":"PCB","Code":null},{"ThesaurusTerm":"Pollution","ThestID":6383,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Pollution","DutchTerm":"Vervuiling","Code":"c_6077"},{"ThesaurusTerm":"Sediment transport","ThestID":7391,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Sediment transport","DutchTerm":"Sedimenttransport","Code":"c_d1a88f2d"},{"ThesaurusTerm":"Water quality","ThestID":9125,"ThesTypID":1,"ThesType":"ASFA Thesaurus List","OrigThesTerm":"Water quality","DutchTerm":"Waterkwaliteit","Code":"c_16061"}],"taxterms":null,"geoterms":[{"GeoTerm":"Belgian Coast","GeoObjectID":2550,"OrigGeoTerm":"Belgian Coast","DutchTerm":"Belgische kust"},{"GeoTerm":"Westerschelde","GeoObjectID":4752,"OrigGeoTerm":"Westerschelde","DutchTerm":"Westerschelde"},{"GeoTerm":"Zeeschelde","GeoObjectID":2546,"OrigGeoTerm":"Zeeschelde","DutchTerm":"Zeeschelde"}],"funderids":null,"othtermsFRIS":null,"pictures":[],"spcols":[{"SpColID":27,"SpName":"ScheldeMonitor"}],"resmessage":"","complete":1}
