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.

Flood protection of City Chrudim
Kostelecký, Jiří ; Půža, Pavel (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis is focused on flood protection of Chrudim city. In the beginning the work is dedicated to documentation of the current condition of the watercourse Chrudimka and to flood control methods used on the river. The following part is dealing with records about floods in given area from history to present days. In the paper work is explained how to behave during the flood and which signals are there to inform. The last part is devoted to sediments in the Chrudimka River and to their impact on clogging of the watercourse of that river and to overall impact on the Elbe River.

Study of sediment transport, flood protection and outline of flood plan in chosen part of the river Thaya
Berka, Ondřej ; Zachoval, Zbyněk (referee) ; Veselý, Jaroslav (advisor)
Bachalor's thesis „Study of Sediment Transport, Flood Protection and Outline of Flood Plan in Chosen Part of the River Thaya“ is divided into four parts. In the first one, I describe chosen part of the river Thaya from the Nové Mlýny to the Břeclav weir with focus on geographic, geological and hydrogeological conditions, hydrotechnical structures and river adjustments, biota and protected areas, demography and Lednice-Valtice Cultural Landscape. In the second part, I determine, by bed load samples granulometric analysis, the source of sediments, which appeard under the Břeclav weir. In the third part, I describe chosen area from the view of flood protection, I describe historical floods and I assess capacity of chosen problematic profiles using HEC-RAS program. In the last part, I focus on flood protection of the village Lednice and of the part of Lednice-Valtice Cultural Landscape, I describe problems of this area in context of flood protection and I suggest outline of the Flood Plan of the Village Lednice.

Splaveninová study of a selected flow
Zouhar, Radim ; Maleňák,, Jaroslav (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis focuses on determination of sediments amount in Svitava river and Křtinský potok, which flows into Svitava river in Adamov. Elements are sedimented at the riverbed bottom if the resulting force caused by the water stream on particles is smaller than the gravitational force. Elements can get into the stream both by washing from surrounding terrain and by material erosion of the riverbed which happens more frequently. Therefore another part of this thesis is suggesting of suitable stabilization measures and flood protection of selected objects. The capacity of riverbeds becomes smaller due to their sedimentation. Particle-size characteristics of sediment runoffs have been prepared and thus the amount of sediment runoffs has been calculated and critically evaluated.

Discharge coefficient of dimensionally small sharp-edged circular orifices
Jinek, Josef ; Veselý, Jaroslav (referee) ; Zachoval, Zbyněk (advisor)
This thesis deal with the determination of discharge coefficient of sharp-edged circular orifice in the bottom. Thesis is supposed to deepen knowledge of this subject and the main goal is to define discharge coefficient based on the done experiment. This measurement set values of coefficient for different orifice diameters and these values were compared with values published in specialized bibliography by different scientists. At the thesis end was made a summary thesis evaluation.
