“…The methodology for solving this issue has been divided into three areas. The first one was the calibration and validation of the Hron [36] and WetSpa [37] rainfall-runoff models, processing the outputs from the ALADIN-Climate [38], KNMI and MPI [39] climate models, and a simulation of the altered minimum flows. The second area was focused on the measurement of abiotic and biotic characteristics and modeling in-stream habitat quality.…”

The study is focused on the objectification of an assessment of the quality of an in-stream habitat in mountain and piedmont streams by the decision-making Instream Flow Incremental Methodology (IFIM) due to climate change. The quality of the habitat was assessed on the basis of a bioindication, represented by ichthyofauna. Sixty-four reaches of 47 watercourses in five river basins in Slovakia, in which ichthyologic, topographic, and hydraulic measurements were performed, were evaluated. The effect of the physical characteristics of the stream channel on the quality of the in-stream habitat has been verified on a number of reference reaches in which the measurements were performed at different water levels. From the set of the data measured, an analysis aimed at determining the impact of individual characteristics on the quality of an in-stream habitat has been carried out. The results show the optimum ratio of the weights of the flow velocity and water depth for an assessment of the quality of an in-stream habitat due to climate change.

“…The aforementioned major drivers result in higher winter runoff and lower runoff during other seasons. However, in different regions of the planet, runoff projections may vary due to dissimilarities in natural (primarily climatic) conditions [46][47][48][49][50]. The present study results demonstrate that even among different hydrological regions of Lithuania, river runoff projections may differ.…”

Hydropower (potential and kinetic energy) is one of the most important renewable energy sources in the world. This energy is directly dependent on water resources and the hydrological cycle. Ongoing climate changes are likely to influence the availability/amount of this energy resource. The present study explores the relationship between climate changes and river runoff, projects future runoff in both gauged and ungauged river catchments, and then assesses how these alterations may affect the future hydropower resources in Lithuania. Runoff projections of the gauged rivers were evaluated applying Swedish Department of Climate hydrological model, and runoff of ungauged river catchments were estimated by created isoline maps of specific runoff. According to an ensemble of three climate models and two Representative Concentration Pathway scenarios, runoff and hydroelectric energy projections were evaluated for two future periods (2021–2040, 2081–2100). The results demonstrated a decrease in future river runoff. Especially significant changes are expected according to the most pessimistic RCP8.5 scenario at the end of the century. The projected changes are likely to bring a negative effect on hydropower production in the country. These findings could help understand what kind of benefits and challenges water resource managers may face in the future.

“…Good examples of such models include: WetSpa (e.g., Wang et al 1996;Safari et al 2009; in Slovakia e.g., Valent et al 2015Valent et al , 2016Rončák et al 2016Rončák et al , 2017a, SWAT (Arnold et al 1998), and MIKE SHE (e.g., Refsgaard, Storm 1990;Tegelhoffová 2010). This article builds on previously published papers dealing with a similar theme and which use several older outputs of global and regional models, climate change scenarios, and various conceptual and distributed hydrological models (Hlavčová et al 2008(Hlavčová et al , 2015Štefunková et al 2013Štefunková et al , Rončák et al 2017b).…”

The aim of this study is to look at the impacts of land use and climate change on extreme runoff regimes in selected catchments of Slovakia, with an emphasis on selected characteristics of hydrological regimes, catchment runoff, and, especially extreme runoff. Changing climate conditions, characterized especially by changes in precipitation, air temperatures, and potential evapotranspiration in future decades, have been predicted by recent outputs of the KNMI and MPI regional climate change models and the A1B emission scenario. The land use changes were characterized by various future land use scenarios. Assuming these scenarios are accurate, the hydrological regime characteristics were simulated by the WetSpa distributed rainfall-runoff model, which was parameterized for the selected river basins with a daily time step until 2100. Changes in the total runoff and its components (the maximum and design discharges), as well as changes in soil moisture and actual evapotranspiration, compared to the current state, confirm the assumption of an increase in the extremes of the hydrological regimes during periods of flood events. The results of the study showed a need for a reevaluation of design discharge values for future designs of water management structures.
