Abstract :
Two acoustic Doppler current profilers were tested in March 1988. The goal of the test setup was to compare two Doppler profilers under operational conditions in shallow waters. The two profilers involved were an RD-DR 1200 system and the profiler implementation on the Sonar Work Station of Rijkswaterstaat. In general, close correspondence was found between the two profilers, although under nonstationary current conditions large differences occurred. Water samples, taken at the test locations, have been analyzed with respect to mass concentration and particle size distribution. For some locations a poor correlation was found between these parameters and the received signal strength
