Centrum Voda (Center Water)

Centrum Voda je výzkumný projekt, který hledá řešení problémů vyplývajících z klimatické změny a jejího vlivu na vodní poměry. Snažíme se nalézat odpovědi na základní otázky, jestli dokážeme zajistit dostatek kvalitní vody nejen pro potřeby člověka, ale i pro naši krajinu, zda se zvládneme vyrovnat s přívalovými povodněmi a jak dále snižovat znečištění vodního prostředí.

Impact of climate change on runoff and development of forest composition in the coming decades in a selected river basin in Slovakia

In this study, the authors dealt with the impact of climate change on the hydrological regime and runoff in a selected river basin in Slovakia. The research also aimed to estimate changes in forest communities during climate change to runoff processes in the river basin. Two scenarios of change of land use with forest communities and two global climate change scenarios were used. Land use change scenarios were created for the entire territory of the Slovak Republic at the Technical University in Zvolen. Outputs from the Koninklijk Nederlands Meteorologisch Instituut (KNMI) and Max-Planck-Institut (MPI) regional climate change models – both with the A1B emission scenario – were also used for this research. Assum-ing these scenarios, the characteristics of the hydrological regime were simulated by the distributed WetSpa rainfall-runoff model. Based on the research results, it can be estimated that the air temperature will increase, especially in winter, which could result in less snow accumulation and increased runoff in the basin.
The Hron river basin will manifest itself in an increase in mean monthly flows, especially during the autumn and winter months. This may be due to higher temperatures and earlier snowmelt in the area. However, we see that due to climate change, runoff will react in the opposite way in the sum-mer. Compared to the current situation, we assume that there will be an increase in the extremes of the runoff regime in the winter and a decrease in the summer and autumn. Climate models suggest a change in the distribution of atmospheric precipitation, which may result in an increase in floods, droughts, and other extreme weather events.

Preservation of drinking water demand from water reservoirs in climate change conditions

This study presents interim results of an evaluation of a potential climate change impact on the preservation of drinking water demand provided by water reservoirs in the timeframe of the year 2050. Hydrological and water sources and demands balance procedures have been applied, including modelling of the storage ability of water resources and water supply systems.

Climate change in dryas and at the beginning of the Holocene – rise in ocean levels and its impact on the migration of civilizations in the Middle East and the Indian Ocean

Today’s history or archeology is nowadays a highly developed field that that has long since surpassed during the twentieth century, its original, rather humanities, focus – at a deeper acquaintance with a number of published articles or monographs, however, you can find a deficit in relation to the relatively recent findings from climate change history.
