De oorspronkelijke kalibratie is gebeurd in 2001-2002 met meetreeksen tot 1999. Sinds dan zijn meer metingen beschikbaar en zijn ook de inzichten in het kalibreren van hydrologische modellen gegroeid. Meteorologische gegevens (neerslag en evaporatie) werden verzameld en gecontroleerd tot en met 2008. Er was duidelijk te merken dat enkele van de pluviografen systematisch minder neerslag registreerden. De berekende debietsneerslagen voor de voorspellingsmodellen, die hiervan gebruik maakten, zijn dan ook duidelijk lager dan de gebiedsneerslagen voor de offline kalibratie.<p>Ook de debiet/peilreeksen voor de 9 te kalibreren modellen werden verzameld en gecontroleerd. Vooral de moeilijk verklaarbare verschillen tussen verschillende QH verbanden en de soms belangrijke plantengroeicorrectie vallen op.<p>De resultaten van de herkalibratie zijn divers. Soms worden met de vroegere parametersets nog altijd goede resultaten bekomen met de langere meetreeksen. Voor andere modellen wordt nu met een lichtjes gewijzigde parameterset effectief betere resultaten bekomen. Er zijn echter ook enkele modellen waar vroeger geen goede resultaten bekomen werden en dit nog steeds niet lukt. Wanneer de neerslagen die berekend werden voor de real time voorspellingsmodellen toegepast worden, zijn steeds significante onderschattingen van de gesimuleerde afvoeren het gevolg.","BibLvlCode":"MS","StandardTitle":"Bijstand modelinstrumentarium hydrologie: hercalibratie van de modellen van het Demerbekken","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2026-06-05 01:37:24.441262","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2010,"DateUpdate":"2021-10-12","DateCreate":"2011-01-10","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":0,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":201325,"ISBN":null,"PubliDate":2010,"IssueDate":null,"Volume":"706_15c","Issue":null,"Pagination":"IV, 37 + 132 p. bijl.","Place":"Antwerpen","Edition":"Versie 2.0","BRefXtra":null,"BRefXtraRR":null,"SerID":24938,"SerRR":"WL Rapporten.
