AMCS Graduate Seminar: Modeling water waves: from tsunamis to the kitchen sink

Start Date: February 14, 2019
End Date: February 14, 2019

By Professor David Ketcheson (KAUST)
 
Surface water waves are a physically important phenomenon with which we all have some experience. They are also surprisingly complex and interesting from a mathematical perspective. I will discuss two recent projects in water wave modeling. The first deals with ocean waves, such as tsunamis, passing over the continental slope. It has long been known that the amplification of such waves is greater than what the traditional transmission coefficient would predict. Recent investigation of this phenomenon has led to a completely new way to apply the method of characteristics to general wave problems with continuously-varying coefficients. The second project is the modeling of a circular hydraulic jump that forms when a jet of water impacts a flat plate, as happens when running the water in a typical kitchen sink. The stability of this jump is a complex and open question.
 
Biography: Dr. David I. Ketcheson is an Associate Professor in the Computer, Electrical and Mathematical Sciences and Engineering Division. He joined KAUST in July 2009. Dr. Ketcheson earned his doctoral and master’s degrees in Applied Mathematics from the University of Washington, where he was a DOE Computational Science Graduate Fellow. His work includes development of efficient time integration methods for PDEs, numerical wave propagation algorithms, the modeling of nonlinear wave phenomena in heterogeneous media, and parallel scientific software.
