R. C. (Charlie) Berger

Dr. Berger is a professional engineer with over forty years of experience in hydraulics, estuarine processes, navigation effects, high velocity channels, and computational modeling.  He is currently a Research Hydraulic Engineer (Emeritus) with the USCE Engineer Research Development Center (ERDC) at the Waterways Experiment Station (WES).

Dr. Berger has primary experience and interest in the modeling of estuaries for salinity intrusion, circulation, and sedimentation.  Dr. Berger has developed computational modeling systems for estuaries, rivers, vessel effects, and hydraulic structures.   As such, he has research interests in computational techniques in hydraulic environments.
