Water management study at the upper part of the Štinkovka stream
Svoboda, Vojtěch ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The diploma thesis deals with the study of water management in the upper part of the Štinkovka river basin based on water management analysis. In the past, there was water in the area that is currently lost. Therefore, a terrain reconnaissance was carried out in the thesis to identify problematic areas and to collect samples for laboratory analysis, which were used for sediment studies. Since 2017, water level monitoring has been carried out using an ultrasonic sensor. Measures are proposed to increase water retention in the landscape. The possibility of sports and recreational boating on the Přední rybník pond with a connection to a cycle path and increase public interest in the area are evaluated.

The limits of movement and quantification of bedload amount for gravel-bed rivers
Roušar, Ladislav ; Matoušek, Václav (referee) ; Tůma, Antonín (referee) ; Veselý, Jaroslav (advisor)
Doctoral thesis in detail and comprehensively deals with mechanic of incipient bedload motion for gravel-bed rivers. This study based on theoretical knowledge, experimental researches, numerical models and field survey extends present knowledge concerning with incipient bedload motion and sediment transport at small relative height and hydraulically rough surface bed for turbulent unaerated free surface flow. Incipient bedload motion and sediment transport have been determined for homogeneous and inhomogeneous bed materials. For homogeneous bed material the velocity profiles have been described by different methods in near the bed. Further, hydraulic flow resistance has been evaluated. In the case of inhomogeneous bed material, static armouring and influence of surface layer sorting on hydraulic roughness have been investigated. The correctness of obtained knowledge has been confirmed on the object of nature-inspired river widening. Results shown, among others, that incipient bedload motion does not depend on relative height or final armouring of surface layer to what extend hydraulic roughness is influenced.

Revitalization of Jankovice stream
Mládek, Tomáš ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The final thesis is focused on assessing the current state of hydrological system in the watershed area Jankovice stream and on draft proposal of food protection measures of the village Jankovice. In the first part of the thesis, there is documented the current situation Jankovice stream, its appreciation and draft measures for a improvement the current state. In the following part, there is the elaboration of the sediment transport balance in the stream. In the last part of the final thesis, there is documented the current state Jankovice stream in the village Jankovice and the stream regulation is designed for the purpose of flood protection of the village.

Study of use of former branches of the river Elbe and the links with the local flow in the village Hrobice
Mládek, Tomáš ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis is focused on assessing the current state of the hydrological system in the cadastral area Hrobice and on a draft proposal of flood protection measures. In the first part of the thesis, there is documented the current situation and its appreciation icluding experiences of inhabitants. In the following part, there are designed several potential drafts. The component of the second part is a draft of the canal for a recreational boating. The bachelor thesis also includes the elaboration of the sediment transport balance in Elbe and the impact of the sediment transport on surroundings nearby.

Studies canal linking the River Elbe in Přelouč
Kavalírová, Anna ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
This bachelor thesis deals with the waterway design and floating channel on the river Elbe near city Přelouč and consists of several parts. The first part describes parameters of floating channel and lock followed by their evaluation. In the next part of the thesis, project adjustments are designed. In the third and key part is the evaluation of the project‘s usability.

Revitalization and flood control on the river Oslava and selected tributary
Kopuletý, Martin ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The thesis is focused on the flood protection of the town of Oslavan on the river Oslava and its tributary Balinka. Sample samples were taken to determine the grain curve. The input data were obtained from the Povodí Moravy s. p. and were calculated in the HEC-RAS program. A level and flood analysis was developed and flood control measures were proposed. The flow was again calculated with the proposed measures and re-analyzed. At the end of the work the proposed measures were evaluated.

The realisation procedure for flood control measures in the selected section of river Oslava
Kopuletý, Martin ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
The thesis is focused on the comprehensive solution of the flood protection measures of the town Oslava on the river Oslava. The territory was subjected to a risk analysis with a graphical representation of risk in the area and potential damage to the property was calculated. In continuity has been proposed appropriate flood protection measure to reduce damage. The economic effectiveness of the measures was carried out and other documentation required for the underlimit tender of the project was elaborated. In the conclusion of the diploma thesis there is another possible use of the diploma thesis.

Water analysis and combating drought in the Rokytná river basin
Říha, Tomáš ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
This diploma thesis focuses on water management analysis of the Rokytná River and finding suitable precautions usable by municipalities when dealing with drought and lack of water in their administrative district. The short research at the beginning of the thesis summarizes problematic of drought and lack of water in the Czech Republic, including the current state and overall context. Next part focuses on the assessment of current state of the Rokytná River basin, based on performed reconnaissance of the basin and processed analysis of a part of the basin delimited from km 0,0 to km 16,7 of the river, between towns of Ivančice and Moravský Krumlov. This analysis concentrates on finding factors, which can contribute to extent of drought impact in this area. It also contains a suspended load study of the waterway, which writes up granularity characteristics and calculation of the amount of transported material from a suspended load sample, taken from the bed of the Rokytná River. The overview of suitable proceedings and precautions follows, based on findings in previous parts of the diploma thesis. The conclusion of this thesis consists of very suggestion of suitable steps and precautions related to particular localities in the Rokytná River basin. Target is to enhance the retention ability of the region and to minimize the impact of both drought and floods. The result of these actions should be the empowerment of environmental sustainability in this particular area. Conclusions of this thesis can be used by municipalities and other administrative bodies when creating an approach of combating drought and when deciding about the implementation of relevant precautions.
