“…New data sources (such as remote sensing (Kuban et al, 2022), radar meteorology (Nechaj et al, 2019;Méri et al, 2021), Lidar measurements (Vorobyeva et al, 2019) experiments on hillslopes, and tracer studies have offered unique opportunities to develop and compare different models of the same type (e.g., distributed) or different types of models (e.g., distributed vs lumped, processbased vs conceptual) on a local and regional basis. The confrontation of catchment experiments with results from catchment modelling has become popular in recent years in the region (Szolgay et al, 2020). This report continues the tradition of the Slovak National Reports to the International Union of Geodesy and Geophysics (IUGG) on behalf of the International Association of Hydrological Sciences (IAHS), (see Szolgay, 2003;2007;.…”

The need to increase understanding of the impacts of changing natural and anthropogenic drivers on hydrological processes on local and regional scales is an essential prerequisite for advancing hydrology and a precondition for solving water resources management tasks. Slovakia exhibits abundant spatial and temporal variability of hydrological processes complicating the generalisation of runoff regimes. Changing climate and recent extreme floods and droughts put additional pressure on improving the observing, monitoring, describing, and modelling of hydrological processes. This paper reviews the response of hydrologic research in Slovakia to these challenges published in international journals from 2019 to 2022. It continues the practice of publishing the review part of the Slovak National Reports to IUGG on behalf of the IAHS (Szolgay, 2003;2007;, which follows the custom of National IUGG Committees to prepare a Quadrennial Report for the IUGG General Assemblies containing comprehensive summaries of national activities in geodesy and geophysics (Szolgay, et al., 2023).

In the present paper we analyzed, the occurrence of annual maximum runoff volumes with t-day durations for a 99-year series of mean daily discharge of the Morava River at Moravský Svätý Ján gauge (Slovakia). The runoff volume is, apart from the peak runoff, another very important hydrological characteristic of a river for flood hazard assessment. The maximum runoff volumes with t-day duration were determined. Subsequently, trends of the annual maximum runoff volumes with t-day durations were identified. We analyzed how the annual maximum runoff volumes of the Morava River have changed over the period 1922-2020 and how they have changed over dry and wet periods. The results indicate that the trends of the annual maximum runoff volumes with t-day durations decrease, especially in wet periods. On the Morava River usually the maximum annual discharges occur simultaneously with the annual maximum runoff volume of waves with a given duration t. However, the corresponding values in terms of significance are not equivalent. Based on the exceeding probability curves of the annual maximum runoff volumes, it is possible to determine to the selected volume Vtmax for different t-days the probability of its exceeding and return period. The Log-Pearson distribution type III was used to determine the T-year values of the maximum runoff volumes with t-day duration.

“…The impact of climate change on the river runoff is a very popular issue of scientific studies, which is considered in many scientific papers (Blöschl at al., 2017;Didovets et al, 2019;Duethmann and Blösch, 2018;Gorbachova et al, 2018;Halmová and Pekarová, 2020;Holko et al, 2020;Loboda and Kozlov, 2020;Kubiak-Wojcicka, 2020;Mostowik et al, 2019;Spinoni et al, 2015;Stagl and Hattermann, 2015;Szolgay et al, 2020). The changes of runoff are caused by many factors, i.e.…”

Based on the results of regular monitoring at 11 meteorological stations in the Ukrainian Carpathians, it was discovered a vivid tendency of air temperature increase. It was defined that thermal gradient in the mountains is much less than it is in the free troposphere; at the small altitude it is larger than it is on the tops of mountains. The largest gradient it is observed in period from March till July, the lowest one in period from November till January. It was revealed the cyclical fluctuations of precipitation, in particular the existence of a modern dry phase. There is a tendency of decrease in wind speed during all seasons, which is more evident in the second part of year. There is also the increase in snow cover depth at high altitude. In spite of climate change the river runoff has not changed essentially for the last decades. Like the precipitation the river runoff is of a cyclic nature too. During the last four decades the increase in evaporation, calculated on the base of water balance, has been observed. There is the tendency of runoff increase in a cold period at the large altitude. In turn the water runoff of rivers, located on low-mountain terrain, decreases in the summer period.
