Analiza hidravličnih razmer na odseku mestne Ljubljanice in Gruberjevega prekopa : diplomska naloga

Kolenc, Matjaž (author), Rusjan, Simon (mentor), Rak, Gašper (co-mentor)

Diplomska naloga analizira hidravlične razmere na reki Ljubljanici in sicer na odseku mestne Ljubljanice in na Gruberjevem prekopu. Predstavljen je pregled nad poplavno problematiko v povezavi z vplivom vegetacije, ki zavira pretok glede na svojo strukturo, velikost in samo količino. Še posebej veliko je vegetacije na Gruberjevem prekopu, kjer obrežna drevesa visijo v vodo. Nato je predstavljeno poglavje o gradbenih konstrukcijah ki so umetna ovira rekam, ki tako povzročajo zajezitve in poplave. To so mostovi in mostni oporniki, prelivi, jezovi, zapornice, pragovi,.. Predstavljen je tudi program Hecras, s katerim smo analizirali model reke Ljubljanice, kot primer diplomske naloge. Na koncu so predstavljeni rezultati, njihova interpretacija in pa primerjava med povratnimi dobami odsekoma mestne Ljubljanice in Gruberjevega prekopa.

• Title: Hydraulic analysis of a reach of Ljubljana river and Gruberjev prekop : graduation thesis

Abstract

My graduation thesis is about analysing hydraulic relationships of a reach of Ljubljana river and Gruberjev prekop. Chapter of flooding is presented. Then correlation with vegetation, which slows down the flow with it's structure and shape is overviewied. Influence of vegetation in reach Gruberjev prekop is highlighted, where among other things, trees are hanging in the river. Next chapter is about construction structures that interfere with the flow. These are bridges and bridge piers, weirs, ….Program Hec-Ras, which is used as analytical model of reach of Lljubljana river is introduced . At the end, we overlook results and interpret the correlation of flow between mestna Ljubljanica and Gruberjev prekop.
