Calibration and Verification of Operation Parameters for an Array of Vectrino Profilers Configured for Turbulent Flow Field Measurement around Bridge Piers—Part II

High-frequency velocimeters used for flow measurements during laboratory experiments allow the user to select range several operation parameters set up instrument optimal velocity measurement. The discrepancies between collected with different configurations can be significant, depending on flume bed configuration and boundary conditions. aim of this paper is quantify differences in profiles measured Acoustic Doppler Velocimeter Profilers (ADVPs) configured using a combination profiling parameters: Ping Algorithm (PA), Transmit Pulse Size (TPS), Cell (CS). Whereas Part I research, goal was identify probe downstream measurement complex hydraulic structure (pier protected riprap) based match rate from other instruments, paper, effect distinct profile turbulent kinetic energy (TKE) demonstrated. Differences ADVPs’ were analyzed through sensitivity analysis intention calculate compare any all three components: streamwise u, spanwise v vertical w two characteristic cross-sections. results show that each parameter change has significant values component when compared Target Configuration (TC). largest root-mean-square-error (RMSE) observed TPS changed, followed by CS PA. Absolute RMSE calculated 4 mm 1 is, average, 6.30 cm/s, 0.90 0.82 cm/s components w, respectively. 4.49 0.88 0.71 PA Adaptive Max interval 4.04 0.63 0.68 For parameters, greater cross-section pier than approach cross-section: 90%, 57% 54% PA, TPS, CS,
