20.500.12556/DKUM-13177 ANALIZA REKE SAVE S PROGRAMOM HEC-RAS NA ODSEKU OD HE VRHOVO DO SEVNICE THE ANALYSIS OF THE RIVER SAVA ACCORDING TO THE PROGRAMME HEC-RAS AT THE SECTION OF THE HYDRO-ELECTRIC GENERATING STATION VRHOVO TO SEVNICA Ob vse bolj nepredvidljivih klimatskih pogojih in posledicah človekovega ravnanja z okoljem je smotrno poznati najnevarnejše odseke poplavnih rek in pravočasno predvideti morebitne katastrofe. S pravočasnimi pravilnimi ukrepi v boju zoper podivjano naravo lahko rešimo celotne ekosisteme v okolju vodotoka. V sodobnem času razvijajoče se tehnologije so zmogljivosti računalnikov omogočile kompleksne hidravlične račune, prikaze in simulacije obnašanja vod. Programi z preprostimi grafičnimi vmesniki so postali uporabniško dostopnejši tudi širši populaciji. Diplomsko delo tako obravnava prikaz uporabe enega izmed teh programov za izračun pretokov in obnašanja naravnih vod, programa HEC-RAS za namene poznavanja obnašanja toka naravnih vod, v dotičnem primeru reke Save na odseku do HE Vrhovo do Sevnice. Obsega opise porečja reke, matematične računske modele uporabljene v programu, pridobivanje in izluščanje željenih hidroloških podatkov, ter rezultate analize. Izračuni so bili narejeni za primer stalnega in nestalnega toka, opravljena je bila analiza rezultatov in primerjava le teh z grafičnimi in slikovnimi prilogami ter grafikoni. Under the increasing unpredictable climate circumstances and consequences of human deeds, it is expedient to know all the dangerous sections of the overflowing rivers and to predict the eventual catastrophes on time. With preventive measures in the struggle against the fierce nature, the entire ecosystem in the area of the watercourse can be saved. In the time of the contemporary developing technology, the capacity of computers made the complex hydraulic calculations, demonstrations and simulations of water conduct possible. Programmes with simple graphic intermediate elements became even more accessible to the broader population. Therefore, this diploma paper is a research about the usage of one of these programmes for the measurement of water flows and the behaviour of natural waters, the HEC-RAS programme with the intention to get the knowledge of natural water steams, on the example of the river Sava at the section of the Hydroelectric Power Plant (HE) Vrhovo-Sevnica. It includes the descriptions of the river basin, mathematical calculating models used in the programme, acquisition and pointing out the wanted hydrological data, and the results of the analysis. The calculation has been made in the case of the steady and unsteady water flow, an analysis was done and a comparison of those with the graphical inserts as well as images and diagrams. reka Sava vodotok HEC-RAS stalni tok nestalni tok the river Sava watercourse HEC-RAS Hydroelectric Power Plant steady flow unsteady flow true true false [B.
