Povzetek

Na podlagi SL indeksa in prirejene metode analize rečnega gradienta so bile analizirane tri reke z namenom ugotovitve recentnih tektonsko aktivnih prelomov. Metodo sva testirala na južnem delu Ljubljanskega barja, kjer reke prečkajo desno zmične dinarsko usmerjene (SZ JV) prelome. Prereze vodotokov sva najprej analizirala po klasični, v svetovni literaturi vsesplošno uveljavljeni metodi (SL indeks), ki pa ni dala uporabnih rezultatov. Zato sva uporabila prirejeno metodo, ki je omogočila določitev aktivnih območij dvigovanja in spuščanja površja zaradi recentnih tektonskih premikov. Ugotovljene anomalije sva primerjala s podatki Osnovne geološke karte 1 : 100.000 in s podatki radarskih meritev vertikalnih premikov z metodo PSInSAR. Tako sva predpostavila pet potencialno aktivnih prelomov, območja kompresije ter ekstenzije. Rezultati te raziskave so lahko dodaten vir informacij pri izdelavi tektonskega modela Ljubljanskega polja in Ljubljanskega barja.
