The theme of this diploma theses is project of the small water reservoir on Mačický brook in cadastral Volenice. Water reservoir is designed mainly for the accumulation function, Water reservoir can improve water flow in the catchment area behind reservoir. In the first part of this thesis is the literature searches which process the topic of the climate changes. Designed reservoir can work as a measure for mitigation one of the consequences of climate change drought. Further this section dealt with possibilities of design of all required elements for project of water reservoir. The second part is focused on the very characteristics of the selected area which are used as base for the design. The third part dealt with the design of the required individual objects for proper operation of the reservoir and their verification by using hydrotechnical calculations and flood wave transformation. Also is specified the design of the integration of the reservoir into the countryside by using riparian vegetation.

The presented thesis deals with the evaluation of the ecological status of small watercourse Meredský creek situated in Central Bohemia. Meredský creek springs in the village of Záborná Lhota, runs through the village of Chotilsko and behind the village of Čím empties into the river Vltava. This creek is affected by the urbanization, in the catchment area there is continual livestock grazing and there are several bigger water areas and smaller ponds situated on the creek. The landscape is completed by the mixed and coniferous forests and meadows. The evaluation rate of the pollution was determined according to the selected physical and chemical indicators of the water quality directly in the flow or evaluated in the laboratory conditions, biological status was determined by the community of aquatic macroinvertebrates (saprobity index, ASPT index, BMWP score, Margalef´s diversity index) and hydromorpohological status (average status) was evaluated too. The final ecological status was evaluated according to the Czech State Standard 75 7221 and requirements given by the environmental quality standards. Concentrations of ammonia, total phosphorus, nitrates, chlorides, dissolved oxygen were accomplished as not meeting environmental quality standards. According to the saprobity index, ASPT index, BMWP score water quality is average. Meredský creek reached the 3rd Class of hydromorphological status. According to the chemical status final ecological status is established as not meeting the requirements of the environmental quality standards and general measures leading to the better ecological status are suggested.

This thesis is focused on water resources which supply drinking water to the city Dobříš and the nearby village Stará Huť.

The second part is devoted to detailed analysis of the area of interest. This mainly concerns the development of population, major employers and amenities. The goal of this thesis is to determine the maximum daily water needs for 2025 based on variables indicators with respect to the land use plan of Dobřiš city and the village Stará Huť. The result values are compared to current yields of all water resources. The final summary proposes the possible solution for emergencies in case of declining yields.

Unconventional technology called "wet method" is a gentle pumping and removal of undesirable sediments not only in ponds and streams, but also in shallow waters, canals, harbors, lakes, recreational water areas and other tanks, decorated in treatment technology and water purification. This is a floating suction dredger WATERMASTER CLASSIC III, which functions as a classic and dragline as one and due to various peripheral devices isvaried uses. This machine is also ideal for repairing the damage during floods because of its versatility.

This thesis contains restoration project of chosen section of Zalužansky brook in Ústecký kraj. Project is processed at the level of documentation for territorial management according to decree no. 499/2006, of buildings documentation. Theoretical part captures professional literature research dedicated to restorations, spatial planning and buildings documentation. Analytic segment closely defines and characterise location of interest at first, although major part consists of designed restoration measures following requirements for creating a building documentation by mentioned decree. Benefit from this thesis is it's possible usage as a background material for documentation created by authorised engineer for water management and landscape planning.

The present thesis deals with the issue of a literature review of surface mining in Most and its surroundings. It focuses on changes in the area due to surface mining, and describes their remedy in several ways. Emphasis is on water treatment and other affected constituents in nature. It also deals with describing a detailed definition of the area and non-productive habitat. The following section contains a methodology for field measurement - infiltration attempt made by a single-cylinder, during which found the average hydraulic conductivity of forests, meadows, successions and ruderals. The experiment was conducted at the lignite quarry dumps Czechoslovak army, Ležáky and Vršany.

This thesis deals with abrasion of Brno reservoir at the position Osada. As a part of the work I calculated the abrasion terminanty through which the prognosis of the shoreline retreat is defined. Due to need of stabilizating of the shoreline and preventing the further shoreline retreat I proposed various solutions of situation by implementing active antiabrasion stabilization. I propose and describe six types of soluting stabilization of particular features and their optional combination in the area of concern. These measures are designed to prevent, or at least significantly slow down, another shoreline abrasion of the Brno valley reservoir

This master thesis is a part of solved project called Natural regeneration dynamic under ecological conditions of gaps on example of School Enterprise Křtiny. In territory Habrůvka, forest district Borky, were created gaps in following forest stand types: beech (BK), mixed (MIX) and spruce (SM). Measurement took place on area of size 0,04 ha called small (S) and large (B) with size 0,1 ha. With concentration on locations: centre (C), mature stand (P), border east (T/E) and border west (T/W). It was measured moisture in all big gap locations (B). Continuous measurement was under way during all the year. From the obtained data was evaluated soil moisture and then compared with soil hydrolimits: wilting point (BV), point of decreased availability (BSD), point of decreased availability of water (LB) and capillary maximum capacity (MKK). Altogether, it was found that location centre (C) contains the highest soil moisture value. This thesis is focused on evaluation of NO3 -, NH4 +, C/N, Cox and mineral nitrogen. It was found out that spruce forest stand type (SM) has the highest concentration of NO3 -, NH4 +, C/N, Cox and mineral nitrogen. On the contrast, it has the lowest C/N ratio. Forest stand type beech (BK) had the lowest NO3 - value, C/N ratio and Cox. When evaluating of location, it was found that mixed forest type (MIX) and beech forest type (BK) are observed values higher on location centre (C). Spruce forest stand type (SM) had no as accurate values as those previous ones. In comparison between the big gap (B) and the small gap (S), there was found lower C/N ratio in the small gaps (S). Cox values were balanced. Mineral nitrogen showed higher values in beech big forest stand type (BK/B) and mixed big forest stand type (MIX/B). On the contrary, spruce forest stand type (SM) had higher values in the small gaps. Evaluation of NO3 - showed that the lowest values were in the beech big forest stand type (BK/B) with a significant difference toward to the spruce big forest stand type (SM/B). By comparing of size and location on a gap, there was found a higher concentration of mineral nitrogen, Cox and NH4 + in all the centers (C) of big gab (B). Total result values were often higher in centre (C). In NO3 - evaluation in the spruce forest stand type (SM) there were found higher values in the mature stand (P) in implementation of both small gap (S) and big gap (B). The data obtained are often very similar and thus can not be clearly and easily evaluated.

This thesis deals with the issue of modern methods of water erosion determination. These methods of measuring soil erosion processes have been used: USLE equation, ERCN program, SMODERP model and application of USLE2D in GIS. Individual results were compared and their applicability was evaluated. Use of individual methods demonstrated big difference between ERCN and USLE results. ERCN also contained outdated values of erosion factors. SMODERP model provides different type of output data and model is not very expanded but outputs of simulation can be used for designing erosion control measures. USLE2D results were almost the same as USLE equation results. This method has the potential to replace manual USLE calculation. SMODERP model has been shown as useful for design of technical erosion control measures.

This thesis pays attention to description of river developement, functioning, and their influence on the watershed landscape. It also focuses on the topic of relationship between rivers, riparian ecosystems, and human society. Those information showed the importance of river existence within the landscape and urban areas. The final part of the literary overview describes how rivers should be implemented into the spatial and landscape planning process in conditions of Czech republic. The methodology for river ecological quality assesment contains three basic levels: the level of the watershed, the level of dams or ponds, and the level of the river itself. This way it is possible to design stabilization and developement measures effectively and conceptually. Special attention has been payed to design a methodology that requires reasonable equipement, reasonable amount of time, and delivers useful high quality data. The methodology has been applied in chosen part of the Pšovka river. Chosen area has been analysed and evaluated accordingly to the designed methodology. Stabilization and developement measures have been designed on three basic levels described above. Those measures aim to stabilize and improve the quality of the watershed, and river including its riparian ecosystems. This is achieved by designing regulations, technical constructions, and vegetation elements.
