Numerical Model of Tides in Pearl River Estuary with Moving Boundary
Publication: Journal of Hydraulic Engineering
Volume 123, Issue 1
Abstract
Pearl River is the largest river system in South China with the city of Hong Kong at its mouth. The delta is one of the most rapidly developing regions in the world. With many river-related civil projects in progress there, the water environment is a major concern in recent years. The horizontal two-dimensional (2D) simulation of tides in the Pearl River estuary is presented. The Abbott-Ionescu scheme, a two-level alternate direction implicit (ADI) scheme, is applied in this model and the third-order upwind numerical discretizations of convection terms for inner points are described in detail in this paper. As there exist intertidal flats in the inner bay that occupy substantial area, a simple but efficient drying-flooding procedure is proposed to simulation this process of the flats. The simulated dry situation near the lower low water level is confirmed by satellite image. The computations are calibrated with the field measurement data and the results are also analyzed in this paper.
