Measuring Water in Motion
Ocean & Coastal Waters
  • ADCPs provide a unique, combined view of the water column--at many depths and at the same time.
  • ADCPs reveal patterns in the distribution of water currents and suspended materials.
  • And ADCPs also record how those patterns change -- in time and space.

Measuring Motion in Water
Underwater Navigation
  • RDI's DVLs are the proven choice for high-tech navigating of submerged vehicles.
  • Since 1992, RDI's DVLs have been delivering both robust & reliable operation and the best technical solution, proven by clients
  • Holding bottom lock over difficult terrain, such as hydrothermal fields on mid-ocean ridges
  • Delivering instant & accurate vehicle velocity for input to critical integrated navigation systems

Measuring Water in Motion
Inland Waters
  • RDI’s ADCPs are changing the way the world measures water currents and discharge in rivers, lakes, streams, and estuaries.
  • ADCPs provide an autonomous moving-boat discharge system, measuring simultaneously all three variables required for computing discharge.
  • The ADCP method permits improved accuracy & safety, time savings, and simplified logistics.

Measuring Water in Motion
Directional Wave Gauging
  • ADCPs measure directional wave data & current profiles at the same time, from a single device  securely mounted on the seabed.
  • The ADCP Waves Array uses its near-surface depth cells to form a set of discrete wave sensors dispersed in space and synchronized in time.
  • Using an array method permits a more accurate & better-resolved measure of wave direction(s) than single point devices.
