Comprehensive laboratory measurements and a thorough review of applicable literature show that electromagnetic current meters (manufactured by Marsh-McBurney, Inc.) are adequate for many kinematic measurements but may lead to excessive errors when using velocity to calculate dynamical quantities (such as bottom friction, Reynolds stress, or log-layer friction velocities). These studies point out a potential difficulty in using these meters in areas of large ambient turbulence levels (20% turbulent intensities), which are characteristic of many near-bottom shallow water environments. Further study is needed to clarify this behavior.
