Sažetak
The paper contains a hydrological analysis of overflow discharges measured at the Rječina spring. The available data included average daily overflow discharges measured in the period from 1 January 1948 to 31 December 2015. It should be noted that measurements at the spring were not conducted in the period from 1 January 1960 to 31 December 1965 and throughout 2001, i.e. the 68-year period contains complete overflow discharge data for 61 years. The average multiannual discharge in the available period equalled 6.85 m3/s. The lowest value of the average annual overflow discharge was recorded in 2011 and amounted to 3.53 m3/s, whereas the highest value was observed in 1951 and equalled 11.21 m3/s. It was determined that a series of average annual overflow discharges can be divided in two time subseries: (1) 1948 – 1979 and (2) 1980 - 2015. In the first subseries, the average annual overflow discharge equalled 7.86 m3/s, whereas in the second one it was lower by 1.76 m3/s, equalling 6.10 m3/s. The number of days per year (N) when the spring runs dry was analysed. Based on available data, the analysis of abstracted water quantities from the Rječina spring was conducted in the period from 1 January 1997 to 31 December 2015. It was reported that the hydrological regime of the spring had a strong natural variability, and it was recommended that detailed interdisciplinary investigations of the spring water should be carried out to ensure its sustainable use and facilitate further development.
