Abstract

Two field tests were completed to compare the performance of an electromagnetic current meter (ECM) with that of an acoustic Doppler velocimeter (ADV) in gravel-bed rivers. Research was particularly motivated by the need to measure flow properties in highly energetic turbulent flows. Measurements were made at 2 field sites, one at moderate velocities and with moderate turbulence intensities, and the other with fast mean velocities and high turbulent intensities. The conclusion is that the older ECM technology provides the more reliable estimates of flow parameters in high turbulence
