“…This occurrence of "warm" water at greater depths in Prošće Lake was already noticed by Gavazzi (1919), who attributed these temperatures to the influence of a Matica River tributary. Sporadic measurements of water temperatures of the Matica River at various times of a year and for various years show values from 7.0 to 11.3 °C (Petrik, 1961), 10.2 °C (Kempe and Emeis, 1985), and 7.6 ± 0.6 °C (Vurnek et al, 2016). As argued by Gavazzi (1919), this tributary water is rich in suspended matter, and therefore has higher density (and higher turbidity) than the lake water.…”

“…Prošće Lake is mainly fed by the Matica River, and to a lesser extent by Sušanj Stream. Matica River is formed by the confluence of two springs, Bijela rijeka and Crna Rijeka and it is 76 ± 8 cm deep (Vurnek et al, 2016). The lake altitude, area, maximum depth and volume are 636.6 m, 682,000 m 2 , 37.4 m and 7.67•10 6 m 3 , respectively (e.g., Babinka, 2007).…”

Internal seiches in a karstic mesotrophic lake (Prošće, Plitvice Lakes, Croatia)

A lake temperature experiment was performed at the Prošće, Plitvice Lakes, Croatia during a 4-month observational period (6 July–4 November, 2019) to investigate the occurrence and characteristics of internal seiches in the lake. Two-minute mean lake temperatures were measured at a single lake point at fifteen depths ranging from 0.2 to 27 m. Analysis of these data provided insight into the previously unknown and rather complex Prošće Lake seiching. Power spectral densities (PSDs) and magnitude-squared coherences (γ2), together with corresponding cross-spectrum phases that were obtained from the hourly mean lake temperature, air pressure and wind speed data, suggested the presence of three vertical modes of an internal seiche. The first mode (V1H1, period of 6.09 h) corresponds to free baroclinic oscillations; the second mode (V2H1, period of 11.64 h) and the third mode (V3H1, period of 25.60 h) are associated with forced baroclinic oscillations of the lake interior. Excitation of the higher vertical modes is attributed to the influence of dense tributary water. Due to this water influence, vertical temperature gradients in the lake interior were relatively weak; consequently, a single thick metalimnion and/or two metalimnetic layers were established, which resulted in the presence of the V2H1 and V3H1 modes, respectively. Additionally, due to the influence of tributary water, the lake did not attain the typical stratification that is characterized by hypolimnetic temperatures of ≈ 4°C. Instead, during the entire observational period, the hypolimnetic temperatures were consistently above 7.6 °C.

Because of their importance, water springs have been the subject of scholarly study since the late 17th century. With the development of science in the 19th, and especially in the 20th and 21st centuries, they became the object of study of various fields and branches of science. The result of the diverse studies of springs is a rich knowledge of their properties and the development of numerous classifications. Most basic classifications were created at the beginning of the 20th century, but a need for interdisciplinary research and classification of springs has emerged in the last twenty years. Today, however, there is no internationally-accepted interdisciplinary classification or database of springs that would facilitate the comparison of researched features and the use of research data. In Croatia, water-rich karst springs, which are attractive phenomena, have been thoroughly researched and classified, while non-karst springs have been examined less. The aim of this paper is to present the development of spring classifications throughout history, to emphasize the variety of research approaches that have been used, and to present the most important modern research of springs in the world and in Croatia.
