Sažetak
Limnigraphs are used to continuously measure 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 watercourse flow in its cross-section is represented by the stage- discharge relationship, called the rating curve. Different software packages are often used for flow conditions modeling 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 paper aims to improve the procedure for measuring flow and water levels in watercourses. Mentioned will be the river Plitvica near Varaždin in Croatia. All measurement difficulties (deposits, sediment, vegetation, and control interventions) are 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 period(s) in a year when flow changes could be expected, which affects measuring. As an extension of the research, there is a plan to provide a spatial database and a map of all measured locations. This spatial database would then be available for scientists and experts within the research area(s). Also, remote sensing techniques will be applied in order to map the watercourse and surrounding vegetation.
