The Development of a Numerical Model to Describe Nonlinear Wave Motions
Speaker: Robert Dalrymple, John Hopkins University
Series: CEE Departmental Seminars
Location: Bowen Hall Auditorium
Date/Time: Friday, April 18, 2014, 4:30 p.m. - 6:00 p.m.
Water wave breaking at the shoreline, a very nonlinear process, creates surf zone turbulence, mean water level changes, and mean flows, such as rip currents. Wave run?up and overtopping are also important aspects of waves at the shoreline. This talk discusses the development of a numerical model using Smoothed Particle Hydrodynamics to describe these nonlinear wave motions. Application to tsunamis is also discussed.
Dr. Robert A. Dalrymple has been the Willard & Lillian Hackerman Professor of Civil Engineering at Johns Hopkins University since 2002. Prior to that time he was the E.C. Davis Professor of Civil Engineering and founder of the Center for Applied Coastal Research at the University of Delaware, where he taught for 29 years.
His research is in the field of coastal engineering, including water waves and their impact on shorelines, structures, and the ocean bottom and natural hazards, such as rip currents and tsunamis. Current research concerns the dissipation of waves propagating over mud and the application of the numerical method smoothed particle hydrodynamics to free surface flows.
Prof. Dalrymple is the chair of COPRI's Coastal Engineering Research Council. He has served on six National Research Council committees related to coastal issues. He was elected to the U.S. National Academy of Engineering in 2006 and is a Distinguished Member of the American Society of Civil Engineers.
He received his degrees from Dartmouth College (A.B., 1967), University of Hawaii (MS., 1968) and University of Florida (Ph.D., 1973). He is a Professional Engineer (Delaware) and a Diplomate in Coastal Engineering.
