Nonhydrostatic numerical simulation of littoral internal waves on an unstructured grid. - 166 p.

Thesis (Ph.D.)--Stanford University, 2005.

In the code development module, a high-order advection scheme for momentum and an unstructured conservative scalar scheme are developed. The momentum advection scheme uses a high-order Eulerian-Lagrangian Method (ELM), based on the kriging interpolation scheme. The unstructured conservative scalar scheme (UCSS) consists of a mass-conserving, hybrid, implicit scalar-advection scheme that can be used as a second-order central or first-order upwind scheme in space. In addition, UCSS uses second-order central differences in space and the 6 method in time to discretize both the vertical and horizontal diffusion terms. Additional enhancements crucial to internal wave simulations are made, including baroclinic filtering, a pseudo-wall momentum input boundary condition and a sponge layer condition.

520 # $a In the code development module, a high-order advection scheme for momentum and an unstructured conservative scalar scheme are developed. The momentum advection scheme uses a high-order Eulerian-Lagrangian Method (ELM), based on the kriging interpolation scheme. The unstructured conservative scalar scheme (UCSS) consists of a mass-conserving, hybrid, implicit scalar-advection scheme that can be used as a second-order central or first-order upwind scheme in space.

520 # $a Internal solitary waves in the South China Sea were also simulated. The simulation captures the depression to elevation conversion of the large-amplitude internal solitary waves, the effect of topography on solitary wave propagation, and the generation of second-mode solitary waves. The effect of the nonhydrostatic pressure is quantified. The simulation results compare reasonably well with ASIAEX observations and other numerical studies on large-amplitude solitary waves.
520 # $a The objective of this dissertation is to conduct nonhydrostatic numerical simulations of internal waves in the littoral ocean, with a goal to address fundamental questions such as: (1) Which physical and numerical issues are critical to simulating littoral internal waves? (2) What can be understood from the numerical simulations with regard to important phenomena of littoral internal waves, such as generation, propagation, and transformation, specifically in the presence of complex topography?
520 # $a The resulting code has been utilized to simulate internal waves in Monterey Bay. The simulations capture internal wave phenomena, such as generation, propagation, and reflection in the presence of complex topography and illustrate the roles of different continental topographic features in shaping internal wave characteristics. A range of possibilities to achieve accurate internal wave simulations is investigated and explored.
520 # $a This research was conducted in two stages: (1) Developing a nonhydrostatic code to achieve the objectives of littoral internal wave simulations, and (2) Studying internal wave behavior in Monterey Bay and South China Sea by using the resulting code.
