This paper presents a methodology to assess the uncertainty of semi-distributed hydrological models by including, in addition to a list of model parameters, additional unknown factors in the calibration algorithm to account for the rainfall uncertainty (using multiplication factors for each separately identified rainfall event) and for the heteroscedastic nature of the errors of the stream flow. We used the Differential Evolution Adaptive Metropolis algorithm (DREAM(zs)) to infer the parameter posterior distributions and the output uncertainties of a SWAT model of the River Senne (Belgium). Explicitly considering heteroscedasticity and rainfall uncertainty leads to more realistic parameter values, better representation of water balance components and prediction uncertainty intervals.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Assessment of the different sources of uncertainty in a SWAT model of the River Senne (Belgium)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-22 01:31:50.384935","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Uncertainty assessment; Rainfall uncertainty; SWAT; DREAM","OtherDescriptors":null,"Notes":null,"AnaPub":2015,"MonPub":null,"DateUpdate":"2018-03-27","DateCreate":"2016-02-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000353073700010","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.envsoft.2015.02.010"},"refs":null,"anarec":{"AnaID":252644,"PubliDate":2015,"Pagination":"129-146","XtraPublOfAnaID":null,"ISBN":null,"Volume":"68","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":123438,"SerRR":"Environmental Modelling & Software.
