The aim of the methodology is to present methods for quantifying the impacts of projected climate change on the water balance when applying adaptation measures in the Czech Republic for the next few decades. Adaptation measures should contribute to the sustainability of the water balance in all major user segments of water use and management in the basin. The main principle is the use of hydrological models to transform climate change scenarios into time series of hydrological conditions and to quantify the overall water balance of the basin using different types of adaptation measures and their implementation over time. Special emphasis is placed on the evaluation of combinations of adaptation measures that cannot be analysed by simplified methods. The methodology is designed to search for the optimal combination of adaptation measures in the assessed catchment. The proposed approach eliminates the shortcomings of effectiveness assessment from the perspective of the exclusive user of the water resource, as the evaluation of the effectiveness of adaptation measures is carried out in the form of a multi-criteria analysis of the evaluation of the outputs of the simulation model for predicting the water balance in the whole basin. This methodology can be used to assess different adaptation measures in all basic segments of water users: agriculture, forestry, energy, water management and others.

Ongoing climate change is causing a global increase in air temperature. While this is leading to an acceleration of the global hydrological cycle, and therefore a global increase in precipitation, the spatiotemporal variability in precipitation is much more complicated. While temperature in the Czech Republic shows a consistently increasing trend similar to that of surrounding countries and the planet as a whole, precipitation can be simplified that long-term averages of annual totals remain and are likely to remain very similar in the coming decades. Rising air temperatures inherently bring increased evaporative demand of the atmosphere and, for the same precipitation, a lower ratio of precipitation to evaporation, i.e. the climatic water balance shows a negative trend.
Hydrogeological aproaches as the tool for the mitigation of negative impact of climate change in water management: Evaluation of qualitative and quantitative aspects of managed aquifer recharge
Rozman, David ; Hrkal, Zbyněk (advisor) ; Rapantová, Naďa (referee) ; Pech, Pavel (referee)
The thesis adresses the issue of efficient use of groundwater resources under the ongoing climate change conditions, which results in reduced natural recharge of aquifers. It focuses on the assessment of qualitative and quantitative aspects of managed groundwater recharge. In addition to a review of the issues of artificial recharge, the thesis provides two outputs. The first one is a critical evaluation of the effectiveness of artificial infiltration in crystalline conditions, typical for a large part of the Czech Republic, where at present artificial infiltration is not a commonly applied procedure. The second key output is the monitoring of the occurrence of new types of micropollutants from the category of so-called emerging pollutants, which may limit the availability of drinking water sources, especially in periods of climatic stress. Research within the PhD project was conducted at several pilot sites and the results are published in peer-reviewed articles. The obtained findings confirm the suitability of the managed groundwater recharge procedure and the considerable effectiveness of attenuation processes of the aquifers in degrading micropollutant pollution.
Isotope hydrogeology and geothermal applications to clarify the origin, the sustainability and the character of groundwater flow: Bohemian and Aquitaine sedimentary basins
Jiráková, Hana ; Hrkal, Zbyněk (advisor) ; Rapantová, Naďa (referee) ; Michelot, Jean-Luc (referee)
Isotopic investigations combined with geothermal applications represent powerful tools for the exploration of groundwater potential as a drinking or geothermal resource. This Ph.D. Thesis combines both approaches, environmental and radioactive isotopes together with temperature data in deep aquifers, in order to enrich and update the knowledge concerning the aquifer recharge processes in the Aquitaine Basin (France) and the aquifer recharge processes and geothermal potential in the Bohemian Cretaceous Basin (Czech Republic). Stable isotopes (18 O, 2 H, 13 C) combined with radioisotope data (14 C, 3 H) are used to estimate the recharge timing and climatic conditions prevailing during the infiltration from the Late Pleistocene up to modern time. The character of groundwater recharge and regime are necessary to generate relevant source data for the accurate modelling of complex groundwater systems. Three groups of groundwater recharge types can be distinguished throughout Europe - (i) continuous recharge and (ii) interrupted recharge during Last Glacial Maximum and (iii) a group corresponding to particular recharge conditions. The contrasted geographic and climate conditions at both study sites in France and the Czech Republic have entailed a great heterogeneity of the recharge conditions and...
Long-term groundwater regime in multilayered water-bearing systems on the example of uranium mining impact on groundwater conditions of the Bohemian Cretaceous Basin, Czech Republic

Lipanský T. (2016): Dlouhodobý režim proudění podzemních vod v hlubokých pánevních kolektorech, na příkladu ovlivnění hydrogeologických poměrů české křídové pánve hornickou činností v okolí Stráže pod Ralskem. Doktorská disertační práce. - Univerzita Karlova v Praze Abstract: This thesis sumerises the development of groundwater regime in a multilayered water-bearing system of the Bohemian Cretaceous Basin in maximal proposed extent of area where the groundwater regime had been affected by mining of radioactive materials near Strář pod Ralskem. The aim of the work was to describe the groundwater regime on the basis of measured monitoring data and map interpolations. The former Uranium mining from Cenomanian sandstone sediments represents the largest human impact on the natural groundwater flow of a multilayered water-bearing system within both the Bohemian Cretaceous Basin and the Czech Republic. Newly created graphs and maps of piezometric surfaces bring an insight into the dynamics of the Bohemian Cretaceous Basin water-bearing system and give an idea of long- term groundwater heads and flow directions development in the studied area. This was achieved despite the fact that this study does not present a hydraulic model, but an interpolation of monitoring data. Maps and grids of piezometric surfaces can be...
