Title :
A comparison of two Doppler current profilers
Abstract :
A comparison of two acoustic Doppler current profilers under operational conditions in shallow waters is described. The two profilers involved were an RD-DR 1200 system and the profiler implementation on the sonar workstation of Rijkswaterstaat. In general, close correspondence is found between the two profilers, although under nonstationary current conditions large differences occurred. Water samples taken at the test locations were analyzed with respect to mass concentration and particle size distribution. A good correlation was found between these parameters and the received signal strength at some of the locations
