An Acoustic Doppler Current Profiler (ADCP) recently developed to measure current distribution in the ocean based on the Doppler shift principle has been tested for limnological studies. We had a chance to test the ADCP in brackish lakes, Nakaumi and Shinjiko, and a tidal river Ohashigawa on 25-27 Aug. 1992, and succeeded in continuous measurements of current distribution in those water areas.<BR>From our test observation, we found that the employment of ADCP in tidal water areas is very effective for rapidly recording current patterns in stratified double layers.<BR>However, ADCP is not so applicable to measurements in shallow water areas or weak current fields, because we cannot measure currents in the layers near the water surface and bottom due to limitations in the acoustic method, and we found that a low current speed relative to navigational speed may result in a large error.
