Abstract

Primarni cilj ovog rada je otkriti je li došlo do promjene u režimu otjecanja i predstaviti moguća predviđanja u budućnosti. Korišteni su satni podaci za koje su prikazani osnovni statistički pokazatelji te je provedena spektralna analiza i Fourierova transformacija. Podaci koji su korišteni dobiveni su iz tri hidrološke stanice, a to su: Kupari, Hrvatsko i Kamanje. Na temelju provedenih analiza zaključeno je kako je primijećena znatna razlika ulaznih signala te da su tijekom godina primjećivani sve veći ekstremi kako u sušnim tako i u vlažnim razdobljima. Iako su rijetki radovi na ovu temu kod kojih se provodi spektralna analiza, ipak ih ima te su uzeti kao temelj pisanja ovog rada, a cilj je bio doraditi ih korištenjem satnih podataka.

Abstract (english)

The primary goal of this paper is to find out there has beed a change in the runoff regime and to present possible predictions in the future. Hourly date were used for which basic statistical indicators were presented, and spectral analysis and Fourier transform were performed. The data used were obtained from three hydrological stations, namely: Kupari, Hrvatsko and Kamanje. Based on the concluded that a significant difference in input signals was observed and that increasing extremes were observed over the years in both dry and wet periods. Altrough there are few papers on this topic that perform spectral analysis, they still exist and were taken as the basis for writing this paper, and the goal was to refine them using hourly data.
