Parmeshwar L. "Pravi" Shrestha, Ph.D., P.E., D.WRE

Dr. Shrestha has over 20 years of experience in the field of water resources and environmental engineering. His expertise in hydrology and hydraulics include a large number of studies for delineating flood hazards including simulation of flooding in alluvial fans, and mitigation of onsite and offsite flood waters. His experience in the area of hydrodynamic and sediment transport include the development and application of finite element (RMA series of models) and finite difference models (ECOMSED, EFDC) for hydrodynamic and sediment transport modeling (both cohesive and noncohesive) and inherent physico-chemical processes in surface water systems. Specific experience includes development and application of numerical models for Sam Rayburn Lake (Texas), San Francisco Bay, San Diego Bay, Clear Lake (California), New York and New Jersey Harbors, Housatonic River (Massachusetts), Lavaca Bay (Texas), Green Bay (Wisconsin), Tannery Bay (Michigan), Lake Waban (Massachusetts), and the Arafura Sea (Indonesia) for purposes of water quality assessment and mitigation of potential adverse effects. Dr. Shrestha has also conducted workshops and hands-on training on the use of hydrodynamic and sediment transport models for Sandia National Laboratory (NM), The Research Center on Flood and Drought Disaster Reduction (PRC), and Stevens Institute of Technology (NJ). His teaching experience includes courses in hydraulics and open channel flow at Virginia Tech and courses on sediment and pollutant transport at the Hong Kong University of Science and Technology.

Dr. Shrestha is currently serving as an Associate Editor for the ASCE Journal of Hydrologic Engineering and the Journal of Coastal Research of the Coastal Research and Education Foundation. He was involved in the Water Environment Federation Watershed and Wet Weather Technical Bulletin Advisory Board. He served on the ASCE Task Committee on Contaminated Sediments and on the ASCE Task Committee on Fluid Mud. He is currently serving on the ASCE Standards Committee KSTAT (Fitting of Hydraulic Conductivity with Statistical Spatial Estimation), the ASCE Surface Water Hydrology Technical Committee, and the COPRI Navigation Engineering Task Committee. Dr. Shrestha served as a member of the organizing committee for InterCoh 2003. He is also a member of the advisory committee for the biennial conference on Estuarine and Coastal Modeling.
