3d Numerical Model for Pearl River Estuary
نویسندگان
چکیده
A 3D numerical model with orthogonal curvilinear coordinate in the horizontal direction and sigma coordinate in the vertical direction has been developed. This model is based on POM (the Princeton Ocean Model). In this model a second moment turbulence closure sub-model is embedded, and the stratification caused by salinity and temperature is considered. Furthermore, in order to adapt to estuary locations where flow pattern is complex, the horizontal time differencing is implicit with the use of a time splitting method instead of the explicit method in POM. This model is applied to the Pearl River estuary, which is the largest river system in South China with Hong Kong at eastern side of its entrance. The computation is verified and calibrated with field measurement data. The computed results mimic the field data well.

Three-dimensional pollutant transport model for the Pearl River Estuary.
In this paper, the development and implementation of a three-dimensional, numerical pollutant transport model, which is based on an orthogonal curvilinear coordinate system in the horizontal direction and a sigma coordinate system in the vertical direction, is delineated. An efficient as well as simple open boundary condition is employed for pollutant transport in this mathematical model. It is...

The Pearl River, with an annual mean discharge rate of ~ 10,000 ms, has profound dynamic and ecological influences on the northern shelf of the South China Sea. A coastal ocean model is set up to simulate the circulation in the Pearl River Estuary and the neighboring coastal regions. In winter the Guangdong Coastal Current, which flows southwestward and passes the mouth of the estuary, forces t...

The rapid economic development in The Pearl River delta region (PRDR) has exerted serious potential pollution threats to areas in the vicinity, which have complicated the task of environmental protection in Hong Kong and Macau. In this paper, a three-dimensional numerical pollutant transport model coupled with a synchronised numerical hydrodynamic model, is developed and employed to simulate th...
متن کاملInvestigating the Impacts of Landuse-landcover (LULC) Change in the Pearl River Delta Region on Water Quality in the Pearl River Estuary and Hong Kong's Coast
Water quality information in the coastal region of Hong Kong and the Pearl River Estuary (PRE) is of great concern to the local community. Due to great landuse-landcover (LULC) changes with rapid industrialization and urbanization in the Pearl River Delta (PRD) region, water quality in the PRE has worsened during the last 20 years. Frequent red tide and harmful algal blooms have occurred in the...
متن کاملDistribution of heavy metals in sediments of the Pearl River Estuary, southern China: implications for sources and historical changes.
The distribution of heavy metals (Pb, Zn, Cd and As) in sediments of the Pearl River Estuary was investigated. The spatial distribution of heavy metals displayed a decreasing pattern from the turbidity maxima to both upstream and downstream of the estuary, which suggested that suspended sediments played an important role in the trace metal distribution in the Pearl River Estuary. In addition, m...
