For the measurement of mean and pulsation velocity components the contact-less measuring technique was used, such as Laser Doppler Anemometry (LDA) and Particle Image Velocimetry (PIV).  Complementary the values of pressure in selected piezometric points on the canal walls were measured. The measurement was carried out in seven different flow regimes. The results of this detailed measurement in selected relatively simple element are used for subsequent calibration and verification of mathematical models with appropriate type of turbulence.
