Simulation Approaches
for Coastal Hazards

SimCenter Series: Natural Hazards Engineering 101
Rescheduling | Date TBD

Abstract

This presentation provides an overview of the available methods for modeling coastal waves. First, an overview of the relevant coastal processes, from shoaling to turbulent mixing, is provided to establish a basis to compare the various modeling approaches. The discussion centers on modeling wind waves, and includes a brief overview of the linear and analytical theory available to quantify coastal transformation, and then follows with a summary of spectral and phase-resolving approaches. Modeling long waves is given next, with a focus on tsunami and surge simulation. Finally, the presentation summarizes techniques to couple the various models with other fluid and structural models, and reviews recent advances on the topic.

If you have questions or concerns, please contact Erika Donald, erikad@berkeley.edu.

Presenter

Patrick Lynett is a Professor in Civil Engineering at the University of Southern California.  He attended Cornell University from 1993-2002, where he received three degrees from the School of Civil and Environmental Engineering. His research interests are directed towards a better understanding of coastal processes, such as nearshore circulations, wave evolution from generation to the shoreline, multi-scale hydrodynamic interactions, and sediment transport. Investigations combine numerical modeling with both controlled experiments and field observations. Short time-scale coastal hazards, such as hurricanes and tsunamis, are of particular interest. Dr. Lynett was a member of the 2005 International Tsunami Survey Team to Sri Lanka, the 2005 Hurricane Katrina Coastal Impacts Survey Team sponsored by ASCE, the post-tsunami survey team in American Samoa in 2009, and numerous surveys throughout the Pacific after the 2011 Japan tsunami. Dr. Lynett has been the recipient of research grants from the National Science Foundation (NSF), the U.S. Army Corps of Engineers, the United States Geological Survey, the Nuclear Regulatory Commission, the NOAA Sea Grant Program, the Office of Naval Research, various California state agencies, and private industry. Notable awards include the Department of the Army Commander's Award for Public Service given for Dr. Lynett’s post-Katrina work, a prestigious Guggenheim Fellowship in 2010, and the ASCE Walter L. Huber Civil Engineering Research Prize in 2013.
