Sekundarni naslov:	Gauging station rating curve extrapolation using HEC-RAS
Sekundarni povzetek:	Rating curve represents stage-discharge relationship and is used to transform observed water level into discharge. At high water levels, the stage-discharge relationship often has to be extrapolated due to lack of measured data. The graduation thesis analyses rating curve extrapolation for gauging station Litija on river Sava. The intent of thesis is to narrow the expansion area of extrapolation. There are different methods for extrapolating stage-discharge relationships and most advanced of them is to use a numerical model. The hydraulic simulation was performed with HEC-RAS, where the river Sava main channel and floodplains geometry had to be surveyed. Using discharge measurements made by acoustic Doppler current profiler (ADCP) and observed water levels, the roughness coefficients of the hydraulic model were calibrated and simulation for high discharges was taken. Due to relative wide floodplains downstream of gauging station, also quasi 2-D simulation using split-flow was taken to verify if 1-D model gives satisfactory results. Comparing both simulations, very good accuracy is established, so the use of 1-D simulation is certified. The final results show about 10 % difference between rating curve developed with HEC-RAS and rating curve used in ARSO.
