Za prikaz dinamike spreminjanja so primerna orodja GIS(Geografski informacijski sistemi), ki omogo~ajo ve~slojno primerjavo linij re~nih strug po posameznih ~asovnihpresekih. V prispevku sta na dejanskem primeru odseka reke Save med medenskim mostom in soto~jemtreh rek prikazana spreminjanje struge reke Save na Ljubljanskem polju v zadnjih 230 letih ter primerjavauporabe »klasi~nih« in sodobnih metod.KLJU^NE BESEDEgeoreferenciranje, vektorizacija, DMV, re~na struga, reka Sava, Ljubljansko polje, GISABSTRACTChanging of Sava's river channel on Ljubljana's fieldChanging of river riverbed is a dynamic process, and with the use of GIS (Geographical Information Systems)tools, this process can be clearly shown. This is achievable due to the šnature’ of GIS and its multi-layerapproach, where the river channel patterns in different years can be easily compared with each other. Inthis article, the changing of Sava's river riverbed in the last 230 years is outlined. In this specific case of theriver Sava, which is on Ljubljana's field, between the Medno's bridge and the confluence of three rivers,there is also the comparison between the šclassical’ and modern methods approach.KEYWORDSgeoreferencing, vectorisation, DEM, river channel, river Sava, Ljubljana's field, GIS113
