Sekundarni naslov: Hydrologic model of Glinščica watershed with program Flo-2D
Sekundarni povzetek: The present work begins with description of two-dimensional mathematical model Flo-2D. Its use, functioning and procedure of modeling rainfall - runoff for watershed of river Glinscica is represented. In addition analysis and comparison of the final results with results of one-dimensional model HEC-HMS is described. In the sensitivity analysis of the Flo-2D model, the influences of different parameters were tested - the loss settings, the Manning roughness coefficient, the Froude number, the control parameter TOL and the computational grid size. Direct runoff was computed with the Flo-2D program via the SCS Curve Number loss method procedure. Flo-2D model was calibrated and validated on measured hydrographs and runoff volume of Glinscica watershed for specific rainfall event by varying input and modeling parameters including the control parameters, the Manning roughness coefficients and the SCS curve numbers. The main part of the work contains a comparison of a two-dimensional rainfall runoff model conducted using Flo-2D model with a one-dimensional model HEC-HMS. Statistical analyses were made with the Root mean square error method - RMSE. The 10-year and 100-year storms were also modeled. The results have shown that differences in calibrated parameters SCS CN between 1D and 2D model is due to different mathematical algorithms and numerical model. The topographic data turned out to be the main deficiency.

Povzetek (ePrints): V nalogi je predstavljen dvodimenzijski matematični model Flo-2D. Opisana je njegova uporaba, način delovanja in postopek izdelave modela padavine odtok za prispevno območje ljubljanske Glinščice. Nadalje je predstavljena analiza in primerjava končnih rezultatov z rezultati enodimenzijskega programa HEC-HMS. V občutljivostni analizi modela je analiziran vpliv različnih nastavitev za upoštevanje izgub, Manningovega koeficienta hrapavosti, Froudovega števila, kontrolnega parametra modela TOL in velikosti računskih celic. Neposredni površinski odtok je bil izračunan s programom Flo-2D po metodi SCS. Model je bil umerjen na osnovi izmerjenega padavinskega dogodka. Postopek umerjanja Flo-2D modela je bil izveden s spreminjanjem vhodnih parametrov in kontrolnih parametrov modela, koeficienta hrapavosti in različnimi možnostmi infiltracijskega koeficienta SCS CN. Glavni del naloge je primerjava rezultatov med enodimenzijskim hidrološkim modelom HEC-HMS in dvodimenzijskim modelom Flo-2D. Rezultate sem statistično ovrednotila z metodo srednjega kvadratičnega pogreška RMSE. Modelirane so bile 10-letne in 100-letne padavine. Razlika med umerjenimi vrednostmi koeficienta izgub SCS CN za 1D in 2D model je posledica različnega matematičnega opisa in numeričnega modela. Kot največja pomanjkljivost med vhodnimi podatki v model Flo-2D so se izkazali podatki o terenu.
