WaterProof’s Luitze Perk says: “Nortek advised us on suitable equipment for our extensive field campaign and delivered the right acoustic instrumentation for the job. Our bottom frames were equipped with Signature ADCP instrumentation to gain information about water flow, water level and (in combination with an optical sensor) suspended sediment concentrations over a two-month period.”
WaterProof took measurements using stationary Nortek Signature1000 ADCPs, as well as the simple-to-use Signature VM vessel-mounted instrument. The Signature VM has found favor with clients due to its ability to rapidly provide high data quality from its five-beam array, accurately measuring both currents and depth, while being designed for easy operation.
The vessel-mounted instrument played a key role in establishing the spatial distribution of velocities, sediment concentrations and tidal prisms (the volume of water moved between low and high tide) across the navigation channels.
“The vertical beam of this vessel-mounted system provides us with a high-resolution echograph, encompassing the entire water column from the water surface to the bottom of the sea, where the highest concentration of sediments can be expected,” Perk adds.
