The analysis is based on daily discharge data of 11 gauging stations in the hydrogeologically non-homogenous Ljubljanica River catchment. For each of the stations, we calculated 24 values of recession constants using a different combination of criteria. Based on these values we determined the influence of each criterion on the final result using statistical tests and graphical approaches. Analysis showed that the recession constants calculated using various methods are statistically significantly different for all gauging stations. The recession constants obtained using the individual recession segment method (IRS) are on average 3.1 days higher than those calculated using the master recession curve method (MRC). The influence of the other two criteria, namely the length of the segment and the period for calculating the initial discharge, is not so obvious, since it is most likely conditioned by catchments" characteristics influencing the time dynamics of the runoff</dc:description><dc:description xml:lang="sl">V prispevku smo analizirali vpliv izbire treh kriterijev na vrednost recesijskih konstant nizkih pretokov, in sicer vpliv izbire metode izračuna, vpliv izbire dolžine segmenta recesijske krivulje (4, 5, 6 ali 7 dni) in vpliv izbire obdobja (celotno obdobje, mesečno, sezonsko), na podlagi katerega se določi začetni pretok, ki določa mejo za vključitev padajočih delov hidrograma v recesijsko analizo. Analiza je izdelana na dnevnih podatkih pretokov 11 vodomernih postaj hidrogeološko nehomogenega porečja Ljubljanice. Za vsako od obravnavanih postaj smo z različno kombinacijo kriterijev izračunali 24 vrednosti recesijskih konstant, na podlagi katerih smo s statističnimi testi in grafičnimi pristopi določili vpliv posameznega kriterija na končni rezultat. Analiza je pokazala, da se rezultati, dobljeni po različnih metodah, statistično značilno razlikujejo na vseh obravnavanih postajah. Vrednosti recesijskih konstant po metodi posameznih recesijskih segmentov (IRS) so v povprečju za 3,1 dan višje od vrednosti po metodi glavne recesijske krivulje (MRC). Vpliv ostalih dveh kriterijev, tj. dolžine segmenta in izbire obdobja, ni tako enoznačen, saj je najverjetneje pogojen z lastnostmi porečja, ki vplivajo na časovno dinamiko odtoka</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-6741ZI2G"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-6741ZI2G" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-6741ZI2G/29552c48-6bf8-4909-97c4-e61bc3add693/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-nc-sa/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-6741ZI2G/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-6741ZI2G" /></ore:Aggregation></rdf:RDF>
