Abstract

Magistrsko delo obravnava poplavno problematiko naselja Preddvor. V naselju je struga hudournika Suha utesnjena in speljana v prepuste oz. daljše zacevitve, katere imajo poddimenzionirane pretočne odprtine. Poleg tega je vodotok pred vstopom v naselje speljan pod mostno odprtino, katere dimenzije so prav tako neustrezne. Namen naloge je bilo izdelati hidrološko hidravlično študijo vodotoka, prikazati obstoječe stanje ob nastopu poplavnih voda s 100-letno povratno dobo in predlagati ureditve za zmanjšanje poplavne ogroženosti. Analiziran je bil predlog umestitve suhega zadrževalnika nad naseljem. Hidrološka študija vodotoka je bila izdelana s programskim orodjem HEC-HMS. Rezultat modela je predstavljal hidrogram odtoka za poplavni dogodek s 100-letno povratno dobo. Za izgradnjo hidravličnega modela smo javno dostopne LIDAR podatke združili z geodetskim posnetkom dela obravnavanega odseka potoka Suha. Podatke smo obdelali z GIS orodji in s pomočjo programskega orodja Civil AutoCAD definirali prečne prereze struge vodotoka. Geometrijo struge smo uvozili v program Hec-RAS, glavni vhodni podatek za model je predstavljal hidrogram odtoka. S hidravličnim modelom smo prikazali najprej obstoječe stanje ob nastopu visokih vod in nato stanje po izgradnji suhega zadrževalnika.

Secondary title: Discussion of the flood problem of the Suha torrent in Preddvor with the flood regulations proposal
Secondary abstract: The master's thesis deals with the flood problematics in the section through Preddvor settlement. In the settlement, the Suha torrent channel is arranged thorugh culverts, which are in terms of floodwater conveyance very problematic. In addition, before entering the settlement, the watercourse runs under a bridge opening, with inadequate hydraulic conductivity. The purpose of the project was to develop a combined hydrological and hydraulic study of the Suha torrent section, present the existing flood problematics in case of floods with a 100-year return period and to propose the flood system. We analyzed the proposal for the placement of a dry reservoir. A hydrological study of the watercourse was made using HEC-HMS software. The result of the model was a floodplain hydrogram for a flood event with a 100-year return period. To build a hydraulic model, publicly accessible LIDAR data was combined with geodetic survey of a part of the torrent channel and processed with GIS tools. Using the Civil AutoCAD software we defined torrent channel cross-sections. The geometry of the riverbed was imported into the program Hec-RAS, the main input into the model was the hydrograph. With the hydraulic model, we first analyzed the existing flood situation and then the situation after the arrangement of the proposed dry retention area.
