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.

Study of sediment transport Moravanský potok flow in relation to extreme flows and drought
Pojsl, Václav ; Půža, Pavel (referee) ; Veselý, Jaroslav (advisor)
This bachelor thesis will concentrate on sediments study of Moravanský potok. In the introduction the study focuses on the description and photographic documentation of the situation of Moravanský potok before and after treatment flow. In following chapters it deals with granulometric analysis of Moravanský potok including the calculation of sediments. The study also describes the morphology of the area and influence by water management ratios. In the final part of the thesis are assessed the survey data of the situation of Moravanský potok and the recommendations how to reduce sedimentation.

The study navigable Odra in the Ostrava - state boundary with Poland
Halaška, Ondřej ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
This bachelor's thesis deals with the problem of navigability of the Odra River from Ostrava to the Polish state border. The development of the European waterway transport together with the current condition of Czech waterways is described and a comparison of water, road and railway cargo transport is made. The next parts of the thesis deal with the historical development of Odra waterways, its route and transport capacity. The last part of the thesis is devoted to hydrological and bed-load ratio of the Odra River, after realization navigability.

Specification of the movement of sediments in the selected section of the flow in the vicinity of the polder Žichlínek
Kaizar, Jan ; Půža, Pavel (referee) ; Veselý, Jaroslav (advisor)
The bachelor thesis defines sediment transport in selected section of Moravská Sázava river, and Ostrovský potok stream in the area of Žichlínek detention basin. The first part of the thesis focuses on documentation of the current situation of the selected area. Following part deals with granulometric analysis of taken samples and their assessment. Next part is dedicated to calculation of the amount of the sediment, and suspended solids in the studied watercourses. The final part of the thesis describes as the sediment transport impacts on both the stream bed clogging, and the passage of a flood wave through the area.

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.

Flood protection in the community Želešice from streams Bobrava and Hajanský potok
Marek, Vít ; Vrba, Jan (referee) ; Veselý, Jaroslav (advisor)
This thesis is a study of flood protection in the community Želešice, Brno-venkov. The theoretical part deals with: the causes of flooding, their dividing and deals with options, how to protect endangered area. Main part includes calculations of the amount of sediment in the river Bobrava and the Hajanský stream, analysis of risks by quantitative expression, suggests to complete the flood plan of the community and a list of designed flood control measures with own technical suggestion. The last point is to consider, whether is the community threatened by backwater from the river Svratka, which the river Bobrava flows into.

Separators, sedimentation tanks including the functions of the retention basins Jeneweinova
Turic, Jakub ; Půža, Pavel (referee) ; Veselý, Jaroslav (advisor)
The subject of this bachelor thesis are the issues of separators and sedimentation tanks, including function of retention basin Jeneweinova in Brno. The current work describes the basic physical and hydrodynamic specifics of water and divides the water pollution. The bachelor thesis describes also particular separation and sedimentation tanks, their purpose and usage. Our study follows up the causes for flooding and utilization of retention basin as flood protection. A part of this thesis is the description of retention basin Jeneweinova, their design, purpose and functions.

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.

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.
