This diploma thesis discusses the issue of finding type of water turbine for very low heads and low discharges, which could be operated as mobile micro hydropower plant in island mode. Thesis deals with summary of appropriate choices of water turbine for needs of micro hydropower plant. Essential part of diploma thesis deals with design of optimized waterwheel. Waterwheel was chosen because commercial high-speed turbines have low efficiency for low heads. Waterwheel was manufactured and measured in laboratories of Fluid engineering. Measurement output was discharge and efficiency characteristic of turbine. The price calculation was made after manufacture.

This diploma thesis deals with returning of modified troughs of small watercourses to the natural state - revitalisation. The general idea of the river beds and water environment revitalisation will be explained in the theoretical part. It will also deal with its history, development and practical application. The practical part will contain an own project creation. It is a project of the adjusted small watercourses bed revitalisation in the level of study. A section of a fine river was used for this thesis. It is called Žďárský Stream and it belongs to the cadastral area Žďár near the Kaplice. Individual parts of the river and its basin will be mapped in this work. It will also consider the hydrological and geographical conditions and it will propose a technical solving for a local revitalisation of the adjusted river bed. It will ínclude natural factors support, the ecological-morphological improvement, the migrational permeability and other links to the river environment.

Thesis deals with the efficiency of inland waterways in the Czech Republic and its measure which would lead to its greater use. For this precaution is considered a project the Weir in Děčín and without this, the project can not proceed in the construction of other projects in the Czech inland waterways. The first part is devoted to the description of inland waterways as part of the trans-European networks. Furthermore there are institutions in charge of the developement and operation of waterways. Legislation defining the rules to ensure continuity of water transport is also important in the developement and operation. The second part deals with positive relationship between freight water transport and economy of the Czech Republic. I describe in the last chapter of the thesis project the Weir in Děčín and the subsequent project of navigability of the Elbe River to Pardubice and construction of the Danube-Oder-Elbe.

Water is an integral part of our life and waterways and areas were and still are an essential part of the public space of our cities and municipalities. We can find public space in every seat and we meet with the water on many of them. The water in public spaces appears in a different form. Whether these are minor elements, such as fountains, drinking water features, or larger water flows and water area. The water in the public space has its indispensable role. It is well known that its presence has a great impact on the well-being of man. Despite the fact that water is really important in the Interior of human settlements, over the years, water has disappeared on many places from public spaces, due to the technical development and development of settlements. The development of human settlements and public spaces takes place constantly from the time they were established. In recent years, the viewpoint of their importance is significantly changing and lot of the seats are aware of their value. The public space is like a living room of the city, thus a representative place. That´s why, the reconstructions of public space are quite often in recent years with use of water elements. The phenomenon of water surfaces is a factor which affecting the sustainable development and quality of life. Public space is not only an important functional element in the big cities. It has a great importance for smaller municipalities too. And just on them the thesis is focused. Their public space is often neglected. As well as water features in the surrounding area, which are uncared-for or extinct. Water in the form of water courses or water bodies have a great potential, in which a lot of possibilities is hidden, with which you can work in the urbanized areas. The goal of this thesis is to find a new role for the watercourses and water areas to be integrated into public space and public space, thanks to this, become a representative and functional part of the village once again.

Degradace půdy zasolováním, zvyšující se teplota a následný úbytek mnonžství srážek v posledních letech vedou k rozšiřování aridních a semi-aridních oblastí (v současnosti pokrývají třetinu pevniny Země). Navíc představují globální environmentální problémy, které, pokud se nebudou správně řešit, můžou vést k vážné celosvětové krizi. V této diplomové práci jsme propojili tato témata a zaměřili se na lepší porozumění role sodných kationtů na vazbu vody v půdní organické hmotě v aridních a semi-aridních podmínkách. Náš cíl byl prozkoumat proces vzniku a stabilitu vodních molekulových můstků a vodních-kationických můstků v půdní organické hmotě, sílu vazby a množství vázáné vody v půdě za využití diferenční kompenzační kalorimetrie. Nasycení sodnými kationty bylo studováno ve dvou koncentračních oblastech. Na simulaci přirozených podmínek v půdách bylo použito nasycení vazebných míst sodnými kationty do 100% a nasycení nad 100% reprezentovalo vysoce zasolené půdy. Výsledky potvrdily význam schopnosti půdy získávat vodu ze vzdušné vlhkosti, podíl vody v půdě vzrůstal s relativní vlhkostí. Vyšší podíl vody v půdě pak způsoboval snížení síly vazebných interakcí, což bylo interpretováno jako fakt, že rovnováha mezi půdní a vzdušnou vlhkostí vede k optimální vlhkost půdy. Přítomnost sodných kationtů ve vzorcích do nasycení 100% měla na množství vody zanedbatelný vliv, ale v přesycených vzorcích umožňovala navázání většího množství vody. V přesycených vzorcích bylo také pozorováno zvýšení síly vazebných interakcí mezi půdou a vodou, což vede k její větší zádrži. Molekulové můstky byli stabilnější ve vzorcích, které obsahovaly Na+. Nejvyšší stabilita byla pozorována u 10% nasycených vzorcích, další zvyšování Na-saturace pak již vedlo k snižování stability molekulových můstků. Hlavním výstupem práce je, že tvorba vodních-kationických můstků stabilizuje půdní strukturu a že má vlyv na sílu a množství vody vázané v půdě, což představuje klíčové aspekty kvality půdy. Je potřebný rozsáhlejší výskum tohoto tématu, aby získané výsledky pomohli optimalizovat půdní manažment v aridních oblastech a také v ostatních oblastech, kde dochází k degradaci půdy.

This thesis deals with the evaluation of hydrological properties variability of soils in forest catchment Tetřívčí brook in the source area Blanice based on selected hydropedological characteristics with respect to soil type, vegetation cover and character of slope. The selected hydropedological characteristics are maximum capillary water capacity, full water capacity, soil infiltration capability - infiltration rate and cumulative infiltration and retention potential of soils. In sum of seven soil subtypes found in forest (coniferous, deciduous and mixed) and meadow (cut and non-maintained) and on the different slope (three categories) were studied in the catchment area. This thesis is built on bachelor thesis, which dealt with the variability of hydropedological characteristics in the experimental pair comparison basins of Tetřívčí and Zbytinský brook. In the thesis were used mainly the measured data obtained from repeated field campaigns in pre- selected sites and data from the database of experimental catchments of Zbytiny. In the selected sites were made soil probes, soil samples were taken using Kopecky cylinders and infiltration measured by a single-cylinder infiltrometer. By laboratory determination and calculation, selected hydropedological characteristics were obtained. The results were...
