Laboratory Modeling of Internal Wave Generation in Straits

Abstract

This project concerned integrated laboratory and analytical modeling of internal tide generation by sea floor topography. A Green function approach was developed to handle arbitrary two-dimensional topography in arbitrary stratifications, and the method was validated through comparison with numerical models and laboratory experiments. The resulting method was encoded as a MATLAB toolbox called iTides. Large scale laboratory experiments were performed at the Coriolis facility in Grenoble, France and the resulting data confirmed the nature of the internal wave generation process in the South China Sea to be the steeping of a weakly-nonlinear, low-mode internal tide. Advances in laboratory experimental techniques for generating and studying internal waves were made, including the first 3D stereoscopic PIV studies of an internal wave field and the development of a novel internal wave generator. A major overview manuscript for the IWISE program was prepared and is in review, and there are nine other publications. The PI and members of his group participated in the 2010 and 2011 field programs.
