20.500.12556/RUL-83428 Koincidenčna verjetnostna analiza visokovodnih valov na sotočju rek Soče in Vipave Coincident frequency analysis of flood waves at the confluence of the Soča and the Vipava rivers V prispevku je predstavljena metodologija koincidenčne verjetnostne analize visokovodnih valov. S pomočjo programa HEC-SSP je izračunan primer koincidenčne verjetnostne analize visokovodnih valov na sotočju Soče in Vipave, pri čemer smo izračunali verjetnostno porazdelitev gladine Vipave v Sovodnjah na osnovi merjenih pretokov Vipave v Mirnu ter izračunanih pretokov Soče na sotočju z Vipavo. Za pridobitev odzivnih krivulj gladine Vipave v Sovodnjah smo izvedli simulacije s pomočjo enodimenzionalnega hidravličnega modela HEC-RAS. Na gladino Vipave na odseku od sotočja do naselja Miren ob visokih vodah močno vpliva povečan pretok Soče na sotočju, ki povzroča zajezitev Vipave in s tem njeno poplavljanje. Za zmanjšanje verjetnosti poplavljanja Vipave na tem odseku bi bilo zato najprej potrebno urediti strugo Soče, da ne bi povzročala zajezitve Vipave v tolikšnem obsegu. In this paper the methodology of the coincident frequency analysis is presented. Using the HEC-SSP program the coincident frequency analysis of flood waves at the confluence of the Soča and Vipava rivers was performed. The probability distribution of water level of the Vipava River in Sovodnje was assessed on the basis of measured discharge data of the Vipava River in Miren and calculated discharge data of the Soča River at the confluence with the Vipava River. In order to obtain the response curves of the water level of the Vipava River at Sovodnje, simulations using a one-dimensional hydraulic model HEC-RAS were performed. The water level of the Vipava River in its lower reach near the confluence is highly influenced by increased discharge of the Soča River at the confluence with the Vipava River, which causes backwater of the Vipava River. In order to reduce the probability of flooding of the Vipava River at its lower reach near the confluence, the backwater effect should be reduced first. koincidenčna verjetnostna analiza HEC-SSP sotočje visokovodni val Vipava Soča coincident frequency analysis HEC-SSP confluence flood wave Vipava River Soča River true false false Univerza v Ljubljani, Fakulteta za gradbeništvo in geodezijo Slovenski jezik Angleški jezik Delo ni kategorizirano 2016-06-13 02:54:16 2016-06-14 08:10:46 2022-11-29 10:07:13 0000-00-00 00:00:00 2014 0 0 Str. 119-137 št. 47 Letn. 27 2014 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 519.2:556.531(282)(497.4) 1581-0267 7409249 1838689 a47av_k.pdf a47av_k.pdf 1 8AC2279FAB30391DCF4A4C410B6996DB 9e1ec003c56af0baf4d76e61b9d885b30228de3905e34c2ce13ca5b48093641b 46f165ad-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/e73dbc9c-b5f7-4b6a-80c5-560d1838fcd8 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=86467 https://actahydrotechnica.fgg.uni-lj.si/si/paper/a47av 0 11b0ef12-6fc5-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164321 Fakulteta za gradbeništvo in geodezijo 0 0 0
