Sažetak
The present paper focuses on problems arising from changes in monitoring technology and methodology used for primary analyses of series of hydrological data of the same type - primarily series of data on water levels and flow rates calculated from them. As consequence of such changes, inconsistencies are encountered in collected data series, which are particularly pronounced in data from hydrological stations on small torrential streams. The inconsistency of collected data is usually attributed to replacement of discrete water gauge reading of water levels with continuous water level recording. Another important change affecting consistency of collected data series is change in primary analyses of collected data that are stored in national hydrological databases. After the initial long-term period when the mean daily flow rates were determined directly from the data on mean daily water levels, the Croatian Meteorological and Hydrological Service (DHMZ) has been carrying out more precise hourly flow rate analyses since 2001. This paper uses several typical examples to analyse changes caused by the mentioned modifications in monitoring and primary analyses method, and gives recommendations for use of available data series.
