Švihov dam, the largest drinking water source in the Czech Republic and Central Europe, has problems with eutrophication. The Švihov dam catchment spreads over 1200 km<sup>2</sup> and supplies over 1.5 million people in the capital of Prague and the Central Bohemian region with drinking water. Due to intensive agricultural activities and a lack of wastewater treatment plants in small settlements, the water quality is deteriorating. As a result, corrective measures need to be taken. Technological Agency of the Czech Republic supported this research which proposes different scenarios for a reduction of water quality degradation in the dam. The Trnávka dam watershed was chosen for study purposes as it occupies one quarter of the Švihov dam watershed. Hydrological balance was established using measured data. Point and non-point sources of nutrients were determined by field research and included in a Soil and Water Assessment Tool (SWAT) model. This study aims to propose complex watershed management to improve the state of the environment in the entire area and to reduce eutrophication. Different management practices would reduce nutrient loads of streams and increase water quality which is the critical factor in dam eutrophication. This research brings methodology and systematic approach to integrated management, and can be applied not only for the Švihov dam, but also for other watersheds, including those which function as drinking water supply.

Abstract Water services, as a necessity for natural ecosystem functions and a key output from public governance, play a crucial role in forming sustainable relationships between natural, economic, and social factors in the development of society. Primarily, these relationships relate to the natural impacts of weather and climate on the variability of the hydrological cycle. Secondary relationships exist between providers and consumers of the services. Services provided by operators of public water supply and sewerage systems are a specific segment of water services. Their sustainability is controlled on the one hand by public regulation and and on the other by a combination of economic, social, and environmental objectives and the means by which they are achieved. The aim of this paper is, based on the parameters of supply and demand, to quantify the most important aspects of sustainable management of water supply and sanitation enterprises in connection with the current model for state regulation. The methodology is based on an examination of consumer behaviour indicators which can be interpreted from ‘water bills’. The comparison of household expenditure on water services in the Czech Republic shows that some are already approaching, and even exceeding, the limit of what is considered social acceptability.

Emergency Water Supply

The source of water supply in Nanchang City is relatively single, and the safety of urban water supply is difficult to guarantee. According to the hydrogeological conditions of the study area, a threedimensional visualization numerical model of groundwater system was established. After the model identification and verification, combined with the target of emergency water supply in Nanchang city, the emergency exploitation of groundwater in Youkou emergency water source was simulated by using the model under different emergency exploitation schemes, respectively. The prediction results show that compared with scheme I and scheme II, scheme III is most suitable for the requirements of well layout, which has the advantages with the minimum drawdown of groundwater level, and the maximum exploitation. For scheme III, under the conditions that the dewatered aquifers are no more than 1/2 and 2/3 of the original aquifer, the emergency exploitation of 36.55×104m3/d and 49.45×104m3/d can be provided, which could meet the emergency water demands of 54.9% and 74.3% of the local residents, respectively.

The Impact

Climate-smart forestry (CSF) consists of an extensive framework of actions directed to mitigating and adapting to global climate change impacts on the resilience and productivity of forest ecosystems. This study investigates the impact of the pan-European 2018 drought on carbon exchange dynamics in typical highland and mountain forests in the Czech Republic, including two coniferous stands (Norway spruce at Bílý Kříž and Rajec) and one deciduous stand (European beech at Štítná). Our results show that the annual net ecosystem CO2 uptake at Rajec decreased by 50% during the drought year in comparison to a reference year with normal climatic conditions. The Bílý Kříž stand is less affected by drought, as the local microclimate ensures sufficient water supply. The European beech forest at Štítná is most resilient against drought and its negative impacts — there we detect no differences in carbon exchange dynamics between the drought year and the reference year. We consider the matching of tree species to site conditions as crucial in the context of CSF, specifically regarding the stand response to water limitation and water supply and demand. Successively replacing spruce with beech trees in areas with high water demand but limited water supply, like Rajec, will support the goals of CSF.
