Dr. Prasad has 20 years of experience in applying surface water hydrology concepts, developing conceptual and simulation models, assessing impacts of climate change, and applying simulation models to address issues related to flood hazard assessments, flood forecasting, water resources planning, and environmental analyses. He has led natural phenomena hazards analyses’ reviews and contributed to environmental impact assessments for new and operating commercial nuclear power reactors for the last 15 years. Dr. Prasad led the revision of the hydrologic engineering safety review guidance including those for precipitation and riverine flooding, dam breach flooding, tsunamis, storm surges, and channel diversions. He also led the development of technical bases to update guidance for nuclear power plant applicants, review of tsunami hazards at nuclear power plants, and perform probabilistic flood hazard analyses. Dr. Prasad led a team of PNNL staff that performed the reviews of post-Fukushima Near-Term Task Force recommended reevaluated flood hazards and flooding walkdowns at operating nuclear power plants. Dr. Prasad led a team of interdisciplinary PNNL scientists in compiling a report describing the effects of environmental conditions on human performance for manual actions related to flood protection and mitigation.

Currently, Dr. Prasad is leading the development of a probabilistic flood hazard assessment methodology tailored after the well-established Senior Seismic Hazard Analysis Committee process for probabilistic seismic hazard analyses. He is also developing an ecosystem services simulation-valuation framework for the U.S. Department of Defense to assist in improved land management at DoD installations.
