Sažetak
Limnigraphs are used for continuous measurement of water levels on watercourses, which are mostly located in a small number of locations, often distant from each other. The relationship between the measured water levels and the flow of the watercourse in its cross section is represented by the stage-discharge relationship, called rating curve. Most often different software packages are used for modeling of the flow conditions within the watercourse, which simplifies the actual (real) conditions. Continuity of the measuring is required to obtain the real situation, despite the fact that it is difficult, due to costs and a lot of required time. For these reasons, the goal of the presented paper is to improve the procedure for measuring flow and water levels in watercourses. Mentioned will be shown on the river Plitvica near Varaždin in Croatia. All measurement difficulties (deposits, sediment, vegetation, control interventions, etc.) will be taken into account. Rescaled Adjusted Partial Sums (RAPS) method will be applied to determine the subseries within the original time series of the averaged daily flow. Such is required to determine the time period(s) in year when flow changes could be expected, which definitely affects measuring.
