Assessment effects substandard tributaries flowing a proportion on Q/h characteristics thin-plate weir with a rectangular cutout
Šmidrkalová, Nina ; Šafář, Robert (referee) ; Žoužela, Michal (advisor)
This master´s thesis deals with the problem of measuring flow, especially using the method of Q/H characteristics. It describes the thin-plate weir and mentions specific channels. The master´s thesis suggests options of monitoring flow capacity in fixed proffiles with free surface. The master´s thesis also includes an experiment, which is focused on simulation of substandard tributary flowing proportions before weirs for determining their effect on Q/H characteristcs. The experiment is carried out on a thin-plate weir with a rectangular notch at the Department of Water Structures at the Faculty of Civil Engeneering in Brno. Another part of the master´s thesis is data processing to get an idea about the impact of the phenomenon in real applications. Finally, options are recommended for follow-up research.

The determination of minimal countercurrent distance of the water surface sensor from the thin-plate V-notch weir.
Kopečná, Monika ; Zubík, Pavel (referee) ; Žoužela, Michal (advisor)
This thesis clarifies the issue of the measuring flows with the help of capacity measurement systems using Q/h characteristics and also describes measuring techniques for determining the water surface level. The various types of measuring weirs and their Q/h characteristics are described in detail. It also mentions the position of the installation of the sensor. The main task is to find a practical minimal countercurrent distance of the water surface sensors used in practice for use with a V-notch weir in the form of experimental measurements in the water management research laboratory at the Department of Water Structures Faculty of Civil Engineering in Brno. The weirs used for this experiment had top angle cutouts of 90°, 53°8´ and 28°4´. The obtained data is evaluated and subsequently the minimal countercurrent distance of the water surface sensor is determined. The thesis also includes recommendations for further research.

Flow in channels with open water level
Palička, Miroslav ; Štigler, Jaroslav (referee) ; Haluza, Miloslav (advisor)
This bacherol thesis deals with steady water flow, in open channels with different cross-sections. The main aim was mathematical derivation of relations for the most favorable water level, graphic representation of those relations and numerical confirmation of results. Practical use and evaluation of results are summarized in conclusion.
