TLDR
In this article, a 3D multilayer, time-dependent, hydrostatic, tidal current model that can compute wetting and drying in tidal flats due to tidal motion in the Ariake Sea is presented.Abstract:
This article describes the development of a three-dimensional (3D) multilayer hydrostatic model of tidal motions in the Ariake Sea and its application. The governing equations were derived from 3D Navier-Stokes equations and were solved using the fractional step method, which combines the finite difference method in the horizontal plane and the finite element method in the vertical plane. This study introduced a 3D, time-dependent, hydrostatic, tidal current model that can compute wetting and drying in tidal flats due to tidal motion. The 3D model was first tested against analytical solutions for three standard cases in a rectangular basin in order to investigate the performance of the model. Then, the model was applied to Saigo fishery port and the Ariake Sea. For standard cases, the numerical solutions were almost identical to the analytical solutions. Finally, the model results for Saigo port and the Ariake Sea show good agreement with the field observations.read more

Finite element modeling of sediment dynamics in the Scheldt
TL;DR: In this paper, a finite element technique was used to simulate the Scheldt Estuary and its adjacent coastal zone in a 2D-3D model. But the authors did not use a 3D model for sediment transport.

TL;DR: In this article , the authors statistically analyzed the prediction results submitted by participants in the tsunami blind contest held at the 17th World Conference on Earthquake Engineering, and they showed that the reproducibility of offshore water level generated due to the tsunami with soliton fission significantly decreased when the nonlinear shallow water equation models (NSWE) was used compared to three dimensional (3D) models.

Semi-implicit finite difference methods for three-dimensional shallow water flow
Vincenzo Casulli,Ralph T. Cheng +1 more
TL;DR: The resulting two- and three- dimensional algorithm has been shown to be fast, accurate and mass-conservative and can also be applied to simulate flooding and drying of tidal mud-flats in conjunction with three-dimensional flows and is fully vectorizable for an efficient implementation on modern vector computers.
