PRASADA RAO, Ph.D.
Principal Engineering Consultant


Professional Profile

Dr. Rao has been working on various hydraulics related problems for the last 15 years. Before joining California State University, Fullerton in 2002, he has worked as Research Associate in the Department of Civil and Environmental Engineering at Duke University and at University of Kentucky. His current work focuses on modeling two and three dimensional free surface and ground water flows, developing parallel versions of the hydrodynamic serial numerical models and developing models that can predict the cascading effects resulting from water infrastructure breakdown.

Dr. Rao’s work has been supported by Bureau of Reclamation, Environmental Protection Agency and Office of Naval Research and NAVO PET. He has developed the parallel version of the TABS-MDS three dimensional hydrodynamic model for ERDC(WES), Vicksburg, MS and the parallel RMA2 model. His Ph.D. dissertation at IIT, Bombay focused on developing high resolution numerical algorithms for solving free surface flow equations.
