Spectral Analysis of Flood Waves in Open Watercourse
The Sava river is one of three longest rivers in Croatia, and therefore very important for water resources management in the Republic of Croatia. The length of the Sava River is 945 km, and its catchment area is 95, 720 sq. km. Because of its importance, the Sava is the subject of continuous hydrological research. This paper contributes to this body of research by outlining the application of spectral analyses. Generally, large floods do not result from a single flood wave, but from a number of successive flood waves. This paper is based on the study whose aim was to carry out spectral analysis of successive flood waves on the basis of measured water levels. By Fourier transformation, spectral density functions were developed from measured water levels. They reflect the hydrological character of the studied watercourse and its catchment area. From stable water wave spectra it is possible to derive synthetic level graphs, which, in turn provide the basis for hydraulic analyses of propagation of successive synthetic water waves.
