Cables can get snagged and fail due to repeated stresses from wave motion. Acoustic signals cannot get through the water-air boundary, are degraded in turbid or choppy water and are expensive. Additionally acoustics may affect marine life which is a topic that has come to the fore in recent times. ...

Additionally, the nature of the environment that these structures operate in bring significant challenges to traditional acoustic or optical systems. It is becoming painfully obvious to these sectors that communication, monitoring and navigational technology and systems must be updated to provide operators with automated and reliable access to data in real time from any ...

(Dave Ozman, USGS) USGS scientists measure streamflow on a tributary of the Souris River in Foxholm, N.D., about 30 miles northwest of Minot. The team is using an acoustic Doppler current profiler to measure streamflow. (Marisa Lubeck, USGS) The record-breaking 2011 Souris River flood crested on July 25 at over 26,000 cubic feet per second ...
This study investigates coupling national scale airborne laser scanning (ALS) and acoustic Doppler current profiler (ADCP) bathymetric survey data for generating stream rating curves. ...
There has been an increasing interest in the use of Acoustic Doppler Current Profilers (ADCPs) to characterise the hydraulic conditions near river engineering structures such as dams, fish passes and groins, as part of ecological and hydromorphological assessments. ...
With the following techniques, WKC have a range of ways to assess the mechanisms that may be causing beach erosion and to find cost effective solutions to minimise it’s impact: Sand particle size distribution analysis Hydrodynamic modelling Beach profiling bathymetric surveys Current measurements utilizing Acoustic Doppler Current ...
The first was equipped with a multibeam echo sounder for bathymetry and the investigation of bed forms, while the second was equipped with two acoustic Doppler current profilers (ADCPs) to map bed roughness, flow velocity, and suspended sediment fields. ...
