Modeling of hydraulic structures often includes the measurement of dynamic pressure fluctuations. The accuracy of the pressure measurements depends upon the geometry of the tap. Flush mounted and chamber mounted transducers were installed in a 1:21 scale model of the U.S. Bureau of Reclamation Blue Mesa dam and spillway. Differences were observed in the spectral characteristics of the two tap designs. Future prototype tests at Blue Mesa will allow model data to be compared with the prototype response.
