This dataset contains measurements of 3D instantaneous flow velocity with acoustic Doppler velocimetry (ADV) in partly vegetated channels with natural-like foliated flexible vegetation and with rigid cylinders. Experiments with natural-like vegetation (F experiments) were carried out at the Environmental Hydraulics Lab of Aalto University (Espoo, Finland), while experiments with rigid cylinders (R experiments) were performed at the Laboratory of Hydraulics of University of Naples Federico II (Naples, Italy). Velocity measurements were carried out for steady, fully developed turbulent flows in partly vegetated channels, along mid-depth transversal transects. 3D instantaneous point velocity was measured with ADV at 200 and 100 Hz, for duration of 120 and 240 s, for F and R experiments, respectively. For each test series three conditions were investigated: F1, F2 and F3, with increasing vegetation reconfiguration (for F experiments); and R1, R2 and R3, with decreasing cylinder density (for R experiments). The ADV measurements for each test run and the video recordings of plants motion (for F experiments) are included in this dataset. The detailed description of the laboratory setup, the experimental conditions, the measurement technique, together with additional information on the provided data are included in the data article linked to this dataset (https://doi.org/10.1016/j.dib.2020.106080).
