A study of a small hydropower plant
Bartůněk, Tomáš ; Špano, Miroslav (referee) ; Dráb, Aleš (advisor)
The aim of this bachelor thesis is the design of a small hydroelectric power plant on the Jihlava River at river km 136.741. The purpose of the construction is to use the hydroelectric potential of the stream for power generation. The subject is also the use of PROTUR turbines at the weir construction. The study includes a technical report, hydraulic and hydropower calculations, drawings and photo documentation.

Study of the flood protection measures
Žiaková, Tereza ; Duchan, David (referee) ; Dráb, Aleš (advisor)
The bachelor thesis focuses on the assessment of the channel capacity and the design of flood protection measures on the Kotojekda river from the mouth to the Morava River up to river kilometre 3,200. The thesis includes hydraulic calculations using a 1D model. As a result, the proposed flood protection measure is in the form of raising the dikes to the design flow of Q20 with a safety elevation of 40 cm. This design, in combination with the previously developed dry reservoir design, provides protection of the area up to Q100 and protection of the surrounding area from flooding.

Comparison of 1D and 3D Hydrodynamic Models in Designing a Hydraulic Object of a Dry Reservoir
Skokan, Jiří ; Dráb, Aleš ; Duchan, David
This article describes and compares computational and result differences in 1D and 3D hydrodynamic models, which are used for capacity assessment of flow control structures. The paper focuses on a considered dry retention reservoir located on the Kotojedka stream near the city of Kroměříž, Czech Republic. Based on project documentation, a detailed 1D steady hydrodynamic model using functions of Microsoft Excel and its native VBA language was created for the functional object. The parameters of the functional object were optimized based on the results of the 1D model. During the 1D analysis, some uncertainties occurred which cannot be addressed using standard or even more complex hydraulic analytical methods, such as formation and course of hydraulic jump, manifestation of overflow and bottom inlet submergence and water surface elevation profile in apron. Experimental physical model research was not undertaken in this case due to the high cost of the model relative to its lower significance compared to other, much larger water structures. Therefore a 3D steady hydrodynamic model could bring the required solution in this case and provide the basis for object parameters optimisation. A 3D model was created using Flow – 3D software. The results were compared on a series of QN flow rates from Q10 to Q10000, where QN represents the discharge with a repetition period of once in every N years.

Feasibility study of the flood protection measures in the localities of Husovice and Židenice at the Svitava river at km 6,000 – 9,000
Hanzlíková, Zuzana ; Höll, Jan (referee) ; Dráb, Aleš (advisor)
Diploma thesis deals with a suggestion of flood protection measures on the Svitava river in km 6,000 – 9,000. Solved locality is found in Brno, particularly in city parts of Husovice and Židenice. Thanks to used joined 1D and 2D model were made hydraulic calculations for peak water stages Q1, Q5, Q20 a Q100. The outputs of hydraulic calculations were used afterwards for creation of maps of flood danger and drawing documentation of flood protection measures.

The use of GIS for the design of blue-green infrastructure
Indrová, Gabriela ; Dráb, Aleš (referee) ; Duchan, David (advisor)
This thesis deals with the description of blue-green infrastructure and its elements. A number of good examples from Czech Republic and abroad are presented. It is followed by an introduction to the GIS software, where are described the basic tools and analyses, together with possible applications. The last part of this work deals with a selected location. In conclusion, for this location were created cartographic outputs describing the existing and planned MZI.

Study of small hydropower station Rajhrad at the Svratka river
Chalupník, Martin ; Špano, Miroslav (referee) ; Dráb, Aleš (advisor)
The subject of the work is the design of the completion of the flow-through small hydro power Plant (MVE) in the weir Rajhrad on the river Svratka in km 34.970. The study is divided into several parts, which include the processing of hydraulic and hydrological substrates, the design of applicable technology and the elaboration of drawing documentation of small hydro power plant. The purpose of a small hydro power plant on the weir Rajhrad is to use the hydropower potential of the river Svratka to generate electricity.

Hydrodynamic model of the Svitava and Svratka rivers in Brno
Račoch, Tomáš ; Golík,, Pavel (referee) ; Dráb, Aleš (advisor)
The Master‘s thesis deals with the assessment of the current state of flood protection in the rivers and floodplains of Svitava (km 0.000 - 2,050) and Svratka (km 26,370 - 33,963) in Brno. Using a combined 1D and 2D numerical model of water flow, hydraulic calculations of the peak flows of Q5, Q20 and Q100 were performed. For calculation, HEC-RAS 5.0.6 was used. The outputs were processed in the form of flood hazard maps and drawing documentation.
