Measurements of waves in Southampton Water and their variation with the velocity of the tidal current

Estuarine and Coastal Marine Science, 1976
Abstract Measurements of waves and currents at one location in Southampton Water show considerable increase in the wave energy when the tide begins to ebb. Some of the theoretical changes in the form of wind-generated waves in estuaries can be simply described using non-time varying currents.

Accurate Velocity Measurement With a Narrowband Doppler Current Profiler

1993
Abstract : Accurate velocity of an ocean going vessel with respect to the water can be determined in real time by utilizing a Doppler Current Profiler (DCP) system. The DCP employs multiple sonar beams with a plurality of bins or returns from various depth segments.

Calculating the Current in the Measurement Circuit of a High-Velocity Microparticle Detector

Measurement Techniques, 2017
The dependence of the current in the measurement circuit of a high-velocity microparticle detector on the parameters of these particles is found. The Ramo–Shockley theorem is used to derive an analytic expression for the current in a series RC circuit.

Current velocity measurements using acoustic Doppler backscatter: A review

IEEE Journal of Oceanic Engineering, 1986
Acoustic Doppler backscattering techniques have been exploited for measuring water velocity for nearly 40 years. Although most early applications centered on measuring ship speed, much work has been done during the last 20 years to adapt the techniques to measure oceanic velocity fields.

An inexpensive instrument for measuring benthic current velocity and direction at sea

Estuarine, Coastal and Shelf Science, 1991
An instrument which measures the velocity and direction of benthic water currents at depths of up to 80 m is described. Characteristics of this meter include: (i) readings are not affected by water flow during sinking or retrieval; (ii) it is portable; (iii) it operates unattended; (iv) it is inexpensive; and (v) it requires only simple maintenance.

Use of Bagnold's velocity meter in laboratory density current measurements

Journal of Scientific Instruments, 1967
A modified version of Bagnold's velocity meter, suitable for determining the mean velocity at a point in a salt water laboratory density current, is described. The dynamic head detected by a small bore Pitot nozzle is balanced by the dynamic head of an opposing jet of fresh water.
