Non-metabolic use of solar energy in plants can be seen as plant thermoregulation driven directly by solar irradiance. Adaptations leading to warming up are particularly important in cold habitats. Cooling processes are needed everywhere where there is short-term or long-term excess of solar energy. Plants are of utmost importance for ecosystem and landscape functioning. Vegetation has a potential to regulate the Earth{\crq}s surface temperature and improve conditions for other living organisms. By regulating energy and water fluxes between land surface and the atmosphere vegetation is closely related to the climate system.

The "Rašeliniště Kapličky" Nature Reserve is situated in the eastern part of the Šumava Mts. The reserve contains different peatland vegetation types - ombrogenous and transition bog parts. The area was partly drained due to extensive mining, pasturing and forestry in the past There are variously old drainage canals now. My thesis contains (i) the evaluation of groundwater table fluctuation and its relationship to vegetation composition and the drainage intensity and (ii) the evaluation of plant species composition in differently drained parts of the peatbog. There was strong relationship between actual groundwater table and precipitation, especially in drained areas, the diversity and the occurrence of expansive species were also related to groundwater table. A map of dranaige network inside the peatbog (1 : 3 500) and vegetation map (1 : 4 000) in the ArcMap programme for GIS environment were constructed. In the most drained part of the area the revitalisation measure was proposed {--} installation of wooden dams for blocking of drainage system.

The aim of the graduation theses was the using bioaccumulation efficiency of plants, especially water mosses, for the monitoring of the occurence of risk elements in surface waters. The graduation theses assess the content of risk elements in this bioindicators in relation to quality of water supply river Malše. Water mosses susceptibly reflect the statement of water environment and they confirm very good quality of water in river Malše and its usability as water supply river in term of content of monitored risk elements (chrome, arsenic, zinc, lead, cadmium, mercury and uranium).

Erosion is a natural life process. But man its activities and accelerating erosion phenomena that threatens one of the most valuable components of the environment - soil, which is difficult to make up for hundreds and thousands of years. The Czech Republic is threatened by water erosion over the third and wind erosion, about one-tenth of the local soil. When we add to the volume of soil that are occupied by new buildings, it turns out that the soil relatively quickly disappearing. This work deals with the calculation and solution of water erosion in the village Protivec, using the universal equation USLE, the modified equation MUSLE and CN curves method. The resulting values are compared with the values of a land adjustment project, landscaping and erosion control measures are proposed.

This master‘s thesis deals with small water power plant Beneš. The first part of the thesis tries to find causes of low efficiency of this power plant. The second part contains suggestions of construction changes for increasing of efficiency – design of new runner blades and basic parameters of new distributor.

The thesis discusses the rights and responsibilities of landowners and water works, from the perspective of both public and private law. Defines land as an object of ownership, defines terms waterworks and focuses on the institutions of the interaction of land and water works. In detail discusses mode of buffer zones, land servitudes and obligations in relation to flood protection.

This diploma thesis deals with a proposal and evaluation of stream restoration measures as an effective tool to achieve good ecological status within the requirements of the Water Framework Directive 2000/60/ES. The main aim of this diploma thesis is to propose stream restoration measures at the Lišanský Brook based on evaluation of hydromorphological status, analysis of land-use changes and anthropogenic modification of the river basin, runoff and water quality assessment. Attention is also paid to the evaluation of the restoration measures in the selected localities on Botič and Litovický Brook. The main method used for the design and assessment of stream restoration measures is a field survey using the HEM methodology (Langhammer, 2014). Land-use analysis and stream adjustment analysis are based on available historical maps. Based on the results, Lišanský Brook is evaluated as moderately modified. The entire river basin is an intensively farmed landscape that has been affected by inappropriate anthropogenic modifications. To improve the current unsuitable stream conditions, it would be convenient to apply complete restoration measures on Lišanský Brook. Keywords: Stream, restoration, habitat, diversity, urban area, rural landscape

Title: First aid in drowning - knowledge and methodology of teaching pupils of the second grade of elementary school Objectives: The aim of this work is to determine the theoretical knowledge of first aid for drowning man of students in the second grade of elementary schools and to create a model lesson suitable for these students. Methods: In the theoretical part of thesis was used research of literature in the first aid and water rescue. The research was conducted by interviewing, the form of survey. Analysis method (Non-numerical one-dimensional analysis) was used for sorting the information which were obtained, synthesis metod was used in their summary. Results: The knowledge of pupils at our elementary schools, picked by us, about the safety rules of water behavior is sufficient. On the other hand, knowledge of specific first aid to drowning man is insufficient. In some cases, there were answers which had more than 90% success, but in the basic questions about behaviour in specific situations, almost 2/3 respondents answered badly. Keywords: First Aid, Water Rescue, Framework Educational Program.

The thesis deals with the importance of water resources and their influence on political development with the example of Kyrgyzstan. The main objective was to find out the role of water resources in domestic politics, how water influences the relationship between Kyrgyzstan and its neighbors, and whether water resources are of interest to the world's superpowers. Geopolitical analysis was carried out on three levels. At national level, water scarcity, uneven distribution and obsolete water systems are a cause of civil discontent. Corruption in the state sphere negates the possibility of modernization of existing water facilities. Water management is dependent on non-governmental associations and foreign financial assistance. At regional level, there is constant tension between Kyrgyzstan, where all the important rivers of the region rise, and the states lying downstream of these rivers. The cause of this tension is different demands of individual states on water use. International treaties address the situation, but are mostly non-functional in the long term. At the supra-regional level, the interests of especially Russia and China collide. Both superpowers seek to prevent US influence in the region. At the same time, they gain a dominant position in Kyrgyzstan in the economic and security spheres....

Změny kvality vody v malých tocích, vyvolané vybudováním čistírny odpadních vod, představují doposud málo studované a přitom velmi aktuální téma současné hydrologie. Tato studie se zabývá popsáním těchto změn a faktorů, které je ovlivňují. Pro účely výzkumu bylo vybráno pět malých, zemědělsky využívaných povodí prvního řádu (čtyři povodí průměrně 6 km2 , jedno 16 km2 ). V každém zájmovém území byla vždy jedna vesnice od 640 do 2 500 obyvatel. Během 7 - 16 let trvajícího měsíčního monitoringu základních indikátorů kvality vody (O2, BSK5, CHSKCr, TOC, konduktivita, N-NH4, N-NO2, N-NO3, PC, P-PO4) byla zachycena stavba čistíren v obcích. Spolu s daty o účinnosti čistíren byly vyhodnoceny změny kvality vody v toku. Identifikované typy změn ukazují na problematické aspekty vývoje kvality vody v malých povodích. Kromě očekávaného rychlého a razantního snížení hodnot zátěže po výstavbě čistírny odpadních vod se vyskytují i odlišné projevy změn - pouze mírné snížení zátěže, stagnace, dokonce i zvýšení koncentrací sledovaných indikátorů. Mezi další typické změny patří navýšení hodnot 1-2 roky před uvedením čistírny do provozu a opožděná nitrifikace v toku způsobená nevhodným provozem čistírny. Mezi nejdůležitější faktory ovlivňující změny patří provoz čistírny, velikost průtoku recipientu, zemědělské...
