Abstract
According to the instructions of the World Meteorological Organization and the legal obligations of conducting hydrological monitoring in the Sava River Basin District in the Federation of Bosnia and Herzegovina, the “Sava River Watershed Agency Sarajevo” has been conducting, planning and organizing hydrometric measurements at its hydrological stations for many years. Additionally, the Federal Hydro-Meteorological Institute performs hydrological and meteorological monitoring at its stations. Taking into account the above information, and the fact that the World Meteorological Organization (WMO) has defined “basic” climatic and hydrological series in the interval of 30 years (1961-1990 and 1991-2020), hydrological/meteorological data for the last two basic series (1961-1990 and 1991-2020) were completed for Sava River Basin, with an exception with regard to the period 1991-2000. The study includes statistical analyses that are typical for the analysis of climatological and hydrological parameters. The analysis was performed at three meteorological stations (MS Sarajevo, MS Zenica and MS Tuzla) and three hydrological stations (HS Maglaj, river Bosna; HS Zavidovići, river Krivaja and HS Olovo, river Krivaja), which have the longest series of observations in the Bosna River Basin. The analysis results obtained for the series 1991-2020 will serve as the basis for analyzing the new series 2021-2050, just as the series from 1961-1990 served as the basis for analyzing the series 1991-2020 in this study.
