Figures & Tables

The range and trend of changes in air temperatures from 1951 to 2020 and in the period before (1951–1988) and during the warming (1988–2020) according to Wrzesiński and Brzezińska (2023), modified.

The location of water gauge stations on rivers studied in Poland (based on data from IMGW-PIB; numbering in accordance with Appendix 1).

Trends in changes of maximum daily discharge in a hydrological year against average maximum specific runoff from 1951 to 2020.

Trends in changes of maximum daily seasonal discharge against the average maximum specific runoff in four seasons in 1951–2020.

Percent share of trends with a defined statistical significance (p) in analysed series of monthly, seasonal and annual maximum discharge from 1951 to 2020.

Changes in average maximum runoff values [%] during the 1988–2020 warming period relative to the 1951–1988 period and their statistical significance (p).

Changes in seasonal average maximum runoff values [%] during the warming period of 1988–2020 relative to the 1951–1988 period and their statistical significance (p).

Percent share of positive and negative differences in average monthly, seasonal and annual maximum discharge during the warming period of 1988–2020 relative to 1951–1988 and their statistical significance (p).

Dendrogram of gauges grouping based on 12 monthly values of the changes in the average maximum specific runoff and the plot of the linkage distance. Note: gauge ID codes in accordance with Appendix 1.

Locations of water gauges grouped based on changes in the monthly average maximum specific runoff during the warming period of 1988–2020.

The scope of changes in average maximum specific runoff (MHq) in the warming period after the 1988 in individual groups, as derived from the grouping presented in Figure 9.

Inventory of rivers and water gauge cross sections and basic hydrological data from 1951 to 2020 after Wrzesinski 2016, 2021, modified (Note: Mq – mean specific runoff; MLq – mean low specific runoff; Types of river regime: 1 –nival poorly developed, 2–nival moderately developed, 3 –nival strongly developed, 4 – nival-pluvial, 5 – pluvial-nival_ Statistically significant change at: p<0_05, p<0_01, * p<0_001)_
