20.500.12556/RUL-84284 Hidrološko modeliranje potoka Mačkov graben s programoma Flo-2D in HEC-HMS diplomska naloga Hydrological modeling of Mačkov graben using Flo-2D and HEC-HMS Diplomska naloga obravnava padavinsko prispevno območje Mačkovega grabna, ki leži v severozahodnem delu porečja Gradaščice in je eno od eksperimentalnih porečij Katedre za splošno hidrotehniko UL FGG. Za namen hidrološkega modeliranja Mačkovega grabna sta uporabljena dva različna programa, Flo-2D in HEC-HMS. Predstavljen je opis njunega razvoja, delovanja ter postopek izdelave modela. V nadaljevanju je predstavljeno merjenje pretokov v naravnih vodotokih s poudarkom na metodi razredčenja ter instrumentu Flo-tracer. Glavni del rezultatov predstavlja izdelava hidrološkega modela v programih Flo-2D in HEC-HMS za porečje Mačkovega grabna. Pri modelu Flo-2D je poudarek na določitvi topografije, vnosu padavin, izbiri metode izgub ter nastavitvi kontrolnih prametrov. Izdelava modela v HEC-HMS zahteva izdelavo modela povodja ter meteorološkega in kontrolnega modela. Sledilo je umerjanje obeh modelov na izbranih merjenih padavinskih dogodkih in pripadajočih hidrogramih odtoka. Prikazana je primerjava modeliranih in izmerjenih hidrogramov za izbrane padavinske dogodke, s pomočjo koeficienta Nash-Sutcliffe pa ovrednotena natančnost obeh modelov v primerjavi z izmerjenimi vrednostmi. Za bolj natančnega se izkaže model v programu HEC-HMS, ki v povprečju dosega višje vrednosti koeficienta. The theme of this thesis is a basin of torrent Mačkov graben which is located in nortwestern part of Gradaščica River basin and is one of the experimental cathments of the Chair of hydrology and hydraulic engineering at UL FGG. With a goal to develop hydrologic model of Mačkov graben two different programs are used: Flo-2D and HEC-HMS. In the first part the development and functioning of both models is presented. It is followed by presentation about measuring water flows in natural torrents with emphasis on dilution method and Flo-tracer instrument. The main part of results includes hydrological modeling using both programs. For the model in Flo-2D is important to correctly determine topography, rain data, loss method and control parameters. The model in HEC-HMS demands the basin, meteorological and control model. In the next step comparison of modeled hydrographs with measured ones was conducted for selected rainfall events. At the end models were evaluated using Nash-Sutcliffe coefficient. The model in HEC-HMS demonstrates higher values of Nash-Sutcliffe coefficient than model in Flo-2D. gradbeništvo UNI HS padavine hidrogram hidrološko modeliranje koeficient Nash-Sutcliffe graduation thesis precipitation hydrograph hydrological modeling Nash-Sutcliffe coeficient true false false [M.
