“…In the case of the Aim River (France), Wawrzyniak et al (2017) determined that when groundwater supply constitutes 16%, it cools the river by 0.68 °C (± 0.13 °C,) and when it accounts for only 2%, it cools the river water by 0.11 °C (±0.01 °C). The analysis of the thermal regime of rivers in Latvia evidenced that lower water temperatures occurred in rivers with high groundwater supply (Latkovska and Apsite, 2016).…”

The paper evaluates changes in the water temperature of the Vistula River – one of the longest rivers in Europe. Mean monthly and annual water temperatures from the period 1971–2017 for 11 stations along the entire length of the river revealed the increasing trends. The mean increase in water temperature in the analysed multi-annual period was 0.31 °C dec–1. In the majority of analysed stations, the key factor determining changes in the water temperature of the river was air temperature. The observed water warming in the Vistula River should be considered an exceptionally unfavourable situation in the context of importance of water temperature for a number of processes and phenomena occurring in river ecosystems. Given the scale of changes, fast measures should be undertaken to slow down the warming.

“…In the case of the Bela River in Slovakia, in the period 1959-2008, water temperature increased by 0.12 °C (Pekárová et al 2011). In Latvia, analysis was performed concerning water temperature fluctuations in the warm half-year (May-October) in division into large, medium-sized, and small rivers (Latkovska, Apsite 2016). Based on data from 36 hydrological stations, increase in water temperature was determined to be prevalent (it concerned more than 72% of rivers).…”

The paper presents an analysis of water temperature fluctuations in four rivers: Nysa Łużycka, Bóbr, Bystrzyca, and Nysa Kłodzka, in south-west Poland (Fore-Sudetic region) in the period 1971–2014. The obtained results show an evident increase in water temperature ranging from 0.15 °C·dec/1 to 0.33 °C·dec/1. Such changes were particularly determined by changes in air temperature. Water temperature increased in two analyzed stations: Zielona Góra and Wrocław by 0.37 and 0.35 °C·dec/1, respectively. While the variability of the rate of warming of particular rivers in the analyzed region should be associated with local factors occurring in the catchments, the contribution of forest cover is of key importance. A change in water temperature constituting its primary parameter will cause further transformation of the discussed river ecosystems. Combined with poor water quality, rising water temperatures can become a factor inhibiting further economic development of the Fore-Sudetic region in Poland.

Effect of Air Temperature Increase on Changes in Thermal Regime of the Oder and Neman Rivers Flowing into the Baltic Sea

et al. 2021

The paper presents long-term changes in water temperature in two rivers, Oder and Neman, with catchments showing different climatic conditions (with dominance of marine climate in the case of the Oder and continental climate in the case of the Neman River). A statistically significant increase in mean annual water temperature was recorded for four observation stations, ranging from 0.17 to 0.39 °C dec−1. At the seasonal scale, for the winter half-year, water temperature increase varied from 0.17 to 0.26 °C dec−1, and for the summer half-year from 0.17 to 0.50 °C dec−1. In three cases (Odra-Brzeg, Odra-Słubice, Niemen-Grodno), the recorded changes referred to the scale of changes in air temperature. For the fourth station on Neman (Smalininkai), an increase in water temperature in the river was considerably slower than air temperature increase. It should be associated with the substantial role of local conditions (non-climatic) affecting the thermal regime in that profile. Short-term forecast of changes in water temperature showed its further successive increase, a situation unfavorable for the functioning of these ecosystems.
