Abstract: On 11 March, 12 March, 15 April, and 16 April, 1991 the United States Geological Survey (USGS), Sacramento, CA, employed a Downward Looking Acoustic Doppler Current Profiler (DL-ADCP) to investigate tidal flow in Carquinez Strait, in the northern reach of San Francisco Bay, California. A Velocity Visualization Program (VEVIP) was developed to analyze the resulting data sets. The program features interactive graphic presentations that allow the user to visually scan through the ADCP data in both space and time. Preliminary analysis suggests characterizations for flood flow (up-estuary), ebb flow (down-estuary), and the transitions between them. Though the technique is not utilized to its full potential here, results suggest that DL-ADCP studies can be effective in improving understanding of flow in Carquinez Strait.
