20.500.12556/RUL-130835 Morfološke značilnosti izbranih hudourniških pritokov Čabranke in Kolpe Morphological characteristics of selected torrential tributaries of Čabranka and Kolpa V diplomskem delu smo popisali morfološke oblike dna strug na dveh različnih geoloških podlagah. Prvo geološko podlago je sestavljal dolomitiziran apnenec, po katerem teče vodotok Belica, drugo pa skrilavi glinavci in peščenjaki, po katerih teče vodotok Potuharica. Analizirali smo vpliv padca vzdolžnega profila struge in širino struge na morfološke oblike ravno dno, brazda-tolmun, stopnja-tolmun in kaskade. Poleg tega smo analizirali tudi vrste naplavin, količino naplavin, velikostne razrede ter zaobljenost prodnikov, ki so se pojavljali pri posameznih morfoloških oblikah. Ugotovili smo, da padec vzdolžnega profila struge vpliva na prostorsko razporeditev morfoloških oblik. Na višjih padcih smo večkrat zabeležili kaskade in morfološko obliko stopnja-tolmun, na nižjih padcih pa ravno dno in brazdo-tolmun. Naši rezultati kažejo tudi na povezanost med širino struge in prostorsko razporeditvijo morfoloških oblik. Na ožjih delih strug smo večkrat zabeležili kaskade, medtem ko smo na širših delih večkrat zabeležili morfološke oblike ravno dno, brazda-tolmun in stopnja-tolmun. Dobro poznavanje morfoloških oblik rečnega dna je pomembno za pravilno in dobro gospodarjenje s hudourniškimi strugami. Naši rezultati kažejo tudi na statistično značilne razlike med višino stopnje in padcem vzdolžnega profila struge. Posledično lahko te rezultate uporabimo pri gradnji prečnih objektov, na različnih geoloških podlagah, kjer želimo graditi take višine stopenj, ki se naravno že pojavljajo tekom struge vodotoka. In this thesis, we mapped the morphology of channel beds on two different geological substrates. The first geological substrate consisted of dolomitised limestone, which is the bedrock of the Belica watercourse, and the second of sintered claystones and sandstones, which is the bedrock of the Potuharica watercourse. We analysed the influence of channel slope and width on the morphological forms plane bed, pool-riffle, step-pool and cascades. In addition, we analysed the types of debris, the amount of debris, and the size classes and roundness of the pebbles occurring in each. We found that the channel slope influences the spatial distribution of morphological forms. Cascades and step-pool morphologies were repeatedly observed on higher slopes, while plane bed and pool-riffle morphologies were observed on lower slopes. Our results show a correlation between channel width and the spatial distribution of morphological forms. Cascades were repeatedly recorded in the narrower parts of the channels, while plane bed, pool-riffle and step-pool morphologies were repeatedly recorded in the wider parts of the channels. A good understanding of the morphology of the riverbed is important for the proper management of torrent channels. Our results show statistically significant differences between stage height and channel slope. These results can be applied to the construction of cross-sectional structures, on different geological substrates, where we want to build step heights that already occur naturally in the watercourse. hudourniške struge padec vzdolžnega profila struge širina struge morfološke oblike ravno dno brazda-tolmun stopnja-tolmun kaskade torrent channels channel slope channel width channel morphology plane bed pool-riffle step-pool cascade true false false [S.
