Rigorous Model

A geographic information system (GIS) was developed for retrieval and display of hydrodynamic and water quality data. To establish such a system, two of the most important challenges are: (1) to establish a rigorous model which captures the three-dimensional and continuously changing characteristics of marine data and (2) to develop interpolation techniques to accommodate for the temporally and spatially scattered distribution of collected data. The developed system not only bridges together a GIS and a database of various physical, chemical and biological geographically based data for efficient retrieval and management of information, but also incorporates advanced display tools designed specifically for marine data. The initial intention of extending GIS for marine application is to mitigate the deteriorating water quality situation in the Pearl River Estuary (PRE).

Abstract. In order to comprehend the salinity transport mechanism,the tidally varying circulation,and salt stratification are investigated in Lingdingyang bay.The conclusions are:When the discharge is moderate,Lingdingyang is a highly stratified estuary,and salt wedge movement is very prominent.The baroclinic circulation is comparatively strong,and strong salinity gradients create a complex three-dimensional flow.A tidal intrusion front moves upstream in flood periods,and distance of movement is longest in flood slack.Because Velocity shear across the interface of fresh and salt water,and intense waves from and break,entrainment is very strong which cause salt water into freshwater.

The Pearl River

A real-time mathematical model for three-dimensional tidal flow and water quality is presented in this paper. A control-volume-based difference method and a “power interpolation distribution” advocated by Patankar (1984) have been employed, and a concept of “separating the top-layer water” has been developed to solve the movable boundary problem. The model is unconditionally stable and convergent. Practical application of the model is illustrated by an example for the Pearl River Estuary.
