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.

Feasibility study of the flood protection measures
Kacálek, Tomáš ; Štěpánek, Jiří (referee) ; Dráb, Aleš (advisor)
This diploma thesis deals with assessment of flood protection measures in Břeclav. Hydraulic calculations of proposal flood events were carried out using 2D numerical model of water flow. Several simulations took account of construction phases and different values of proposal discharge. The hydraulic calculations were computed for river Thaya including its relief branch. The results were processed in the form of inundation maps, depth maps and they were recorded in longitudinal profiles of rivers.

Suspended Sediment Load Balance in a Selected Profiles of the Thaya and Svratka River Basins
Priesner, Radek ; Mikl, Libor (referee) ; Marton, Daniel (advisor)
The balance of suspended sediment, i.e. undissolved substances carried in suspension, load in the hydrometric profiles Hevlín/Thaya, Přibice/Jihlava, Znojmo/Thaya and Židlochovice/Svratka is evaluated in this thesis. The measurements and the subsequent evaluation of the suspended sediment are carried out according to the official Austrian methodological manual, so this paper is a continuation of the previously written bachelor thesis. In addition, the selected basic steps recommended by the Austrian methodology for the actual measurement of the suspended sediment are compared with official procedures from the United States and the Czech Republic. On top of that, the work comes with innovative ways of correcting the data measured by the optical probe. The results will be used in the project ATCZ28 SEDECO – Sediments, ecosystem services and interrelation with floods and droughts in the AT-CZ border region, from which the measurement records from 2019 to 2022 themselves are available. All results are also compared with the measurements of the Czech Hydrometeorological Institute.
