Abstract :
During the last couple of years, RDI´s WorkHorse ADCP has provided a new method to measure unambiguous directional wave spectra, current profiles, and water level at the same time. Much more than duplicating traditional methods and devices, a single ADCP provides a spatial array of measurements for measuring the wave field directly. This array enables creation of high-definition polar plots of wave direction that separate, rather than smear, waves of similar frequency from multiple directions. ADCPs measure a complete frequency-direction wave spectrum. Further, the ADCP measures the surface-layer currents that can distort the wave field. Recent results are shown that demonstrate the unique advantages of this new technology - notably an ADCP-based analysis of waves can avoid some of the assumptions required by more traditional methods because new types of data are being collected by the ADCP. This new capability is available as an upgrade for WorkHorse ADCPs in the field.
