This diploma thesis addresses Building Information Management (BIM) and its application in water management. The basis of the work is broad research on BIM. Subsequently, the application of BIM is demonstrated in the construction of a small hydroelectric power plant in the Litovel water management node. To conclude, the added value of using BIM and its possible disadvantages for water management are formulated.

There is an obligation to hold a minimal flow when running a water power plant in a current czech legistation. There are environmental reasons to determine the minimum discharge and the way to set it is not valid at the moment. We can see a difference in a type of water power stations when comparing the effects from electric power which is produced in water power plant situated on czech rivers and the damage that does not appear on the environment. The weir type of power plant harms the surroundings mildly except of the possible migration obstacles. But the derivation type makes loss that could be hardly compensate by the produced electricity. Different methods of evaluating the enrironment brinks various results and that is the reason why it is hard to say how much the effects from producing the electricity exceed the benefits arising from instream water or vice versa. The only conclusion that can be said is the advice about including more points of view when setting the minimum flowage.

This Master 's thesis deals with the topic of protection of generators in case of faults, short circuits and their calculation according to the valid standard ČSN EN 60909-0 ed.2. The practical part includes the calculation of the minimum and maximum short-circuit currents of the Lipno I hydroelectric power plant at various locations using the NetCalc calculation program and for comparison of program funcionality provides the manual calculation. Next chapter deals with the calculation of settings of each protection function of the SIEMENS Siprotec 7UM622 protection relay, which is used to protect main generators of this hydropower plant.

Badhus – Industrilandskapet i Norrköping Norrköping har behov av ett nytt badhus. Centralt i staden, längs Motala ström, finns Industrilandskapet som till stor del består av kulturell och vetenskaplig verksamhet men har en lång historia av textilindustri. Det nya badhuset är placerat i detta område; på ett befintligt vattenkraftverk. Syftet med projektet är att tillvarata Industrilandskapets kontrastrika själ, förstärka de rum och potentiella mötesplatser som finns samt ge Norrköping en möjlighet till friskvård och sportutövande. Målet är att visa hur en ny byggnadskropp relaterar och anpassar sig till den kulturella, platsspecifika och historiska kontexten. Byggnaden intar formen av en rektangel som skjuter upp ur slänten, likt en bergsrygg som sluter platsen. Byggnadskroppen aktiverar befintliga kvalitéer såsom den gamla stenbelagda trappan i väster och universitetsparken vid vattnet i söder. Byggnadens norra sida syftar till att ta emot och avsluta rutnätstaden i skala och uttryck. Den södra sidan av byggnaden tillsluter och definierar strömrummet med sin långsträckta fasad. Byggnadens interiör vänder sig utåt mot strömrummet så att det inifrån skapas en öppenhet åt söder gör industrilandskapet till en del av byggnaden. På entrévåningen ligger bassängerna vars vattenytor är visuellt kopplade till Motala ström i flera nivåer. Sutterängplanet inhyser omklädningsrum, det befintliga kraftverket samt fysioterapiavdelning med motionssal. / Public Bath – The Industrial Landscape in Norrköping   Norrköping is in need of a new public bath. In the centre of the city, along Motala ström, the industrial landscape is located. This area hosts cultural and scientific activities but has a long history of textile industry. The new public bath is located in this area on an existing water power plant. The aim of the project is to maintain the contrasty soul, enhance the spaces and potential venues that already exist and give Norrköping a possibility for wellness and exercising. The goal is to show how a new building adjusts and relates to the site specific and historical context. The building is shaped as a rectangle rising from the slope. It activates existing qualities such as the old stone stairs in the west. The north side of the building aims to receive and end the grid city in scale and expression. The south side with the long façade defines the river space. The interior faces the river and creates openness towards the south. Thereby the industrial landscape becomes part of the building. The swimming pools are located on the entrance floor and the surfaces of the water are visually linked to the river. The changing rooms, the power plant and the physiotherapy are placed in the basement.

The purpose of the diploma thesis „Design of a movable weir on the Želivka river" is a design of the reconstruction of a fixed weir in Soutice village on the river Želivka at km 1,639. The first part of the thesis deals with the localization of the area of interest and a description of all documents needed for the weir design. The first part also includes a short search of the considered structures, the findings of which are further applied in the design of a movable weir structure. Furthermore, the work continues by determining the design flow and selecting a suitable structure of the fixed weir substructure and movable closure, which is fitted to the substructure. Based on the selected types of structures, hydrotechnical calculations are performed, which also include a partial assessment of the weir stability. The thesis ends with a technical description of the proposed objects and a final evaluation of the determined achievements of the work. Part of the study is a drawing part documenting designed objects.

The main subject of the diploma thesis „Contradiction analysis of small water power Ostravice“ is solution of reduced output of small water power plant on the river Ostravice near the town Vratimov. Power plant equippment is axial flow Kaplans turbine RA – 3,5 – 0 1000 with runner diametr 1000 mm. Low output is caused by draft tube. New draft tube is designed in this masters thesis. For hydraulic layout was used CFD software Fluent. The aim of this work is finding of optimal shape which leads to increasing of power from current 30 kW to projected 55 kW.

The Master‘s thesis is focused on measuring of the stress in the spiral case of water turbine using the strain gauges measurement. It contains the theoretical and the practical part. The theoretical part includes a description of theoretical background (basic mechanics, measurement and evaluation, strain gauges, pressure measurement, uncertainty of measurement). One of the chapters describes Water Power Plant Lipno nad Vltavou (history of power plant, issues and the history of measurement). The practical part contains a theoretical calculation of measurement uncertainty and measuring of stress on spiral case Francis turbine at Water Power Plant Lipno I (Unit TG2). Measurement was made before and after overhaul. There are described technical data of spiral cases, description of measurement, results of measuring of strain and stress including comparison with the pressure in spiral case and calculation of uncertainties of measurement.
