Abstract:

This paper examines the conservative properties of several numerical treatments of the salt conservation equation. Specifically, computationally efficient first and second order Eulerian-Lagrangian Methods (ELM) are compared against (1) fully conservative finite volume methods including upwind, LUICKEST and QUICKEST. This paper shows that under the numerically rigorous requirements of long-term estuarine transport, that the non-conservative nature of ELM may be problematic. Moreover, solution of advective terms using any of these methods is shown to be a small percentage of the overall computational effort in hydrodynamic models: arguments over their relative computational efficiency is merely academic.
