Effect of options measurement profile in the hydromeasuring process
Jurčová, Michaela ; Žoužela, Michal (referee) ; Zubík, Pavel (advisor)
This bachelor thesis is focused at effect of options measurement profile in the hydromeasuring process. When based on processing of acquired data sample we can determine proper relative distanc measurement profile behind outfall pipe. Determination of proper profile is based on condition that measurement error must be less than 5%. Measurements were assessed at testing track at institute of water structures. Outcome is graph of dependence of percent deviation of determined flow to relative distance behind outfall pipe and relative filling height.

Metrological characteristics of current velocity meters using the electromagnetic principle of measurement
Vítů, Martin ; Brázda, Martin (referee) ; Žoužela, Michal (advisor)
This master’s thesis deals with the assesment of directional sensivity and accuracy of current stream velocity using electromagnetic induction meters in circumstances simulating the real measurement profiles condictions. The theoretical part of the thesis describes the issue of streamflow measurement in open channels and determination of the relevant measurement uncertainties. It also includes description of the hydraulic circuit and the subject current velocity meters. The experimental part of the thesis focuses on the effect of turbulence on the value and accuracy of measured velocity and directional sensivity of electromagnetic induction meters of current velocity. The results are compared with parameters given by manufacturers, research by other authors and with the metrological characteristics of hydrometric propellers, which are commonly used for streamflow measurement in open channels.
