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

Flow mapping around bridge piers is crucial in estimating scour development potential under different flow conditions. The reliable measurement of turbulence and the estimation Reynolds stress can be achieved on scaled models controlled laboratory experiments using high-frequency Acoustic Doppler Velocimeter Profilers (ADVP) for measurement. aim this paper was to obtain operation parameters an array Vectrino turbulent field reliably measure piers. Laboratory were conducted a river model set up open channel hydraulic flume. data measured three characteristic profiles, each containing five points collected by ADVPs configured as two instruments. determination done two-step process—calibration through flume’s pump rate verification with Current Profiler RioGrande data. Based results, following setup ADVPs’ used hole next pier: adaptive Ping Algorithm, Transmit Pulse Size 4 mm Cell 1 mm.
