3d Numerical Model for Pearl River Estuary
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...
متن کاملThree-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...
متن کاملCoupled Physical-Biological Model for the Pearl River Estuary: A Phosphate Limited Subtropical Ecosystem
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...
متن کاملNitrification and inorganic N in the Pearl River Estuary
We investigated the spatial distribution and seasonal variation of dissolved inorganic nitrogen in a large perturbed estuary, the Pearl River Estuary, based on three cruises conducted in winter (January 2005), summer (August 2005) and spring (March 2006). On-site incubation was also carried out for determining ammonium and nitrite oxidation 5 rates (nitrification rates). We observed a year-roun...
متن کاملAnalysis of change of red tide species in Yodo River estuary by the numerical ecosystem model.
Occurrence number of red tides in Osaka Bay in Japan is more than 20 cases every year. Diatom red tide was dominant in Osaka Bay, but the non-diatom red tide was dominant in early 1990s. Therefore, the material cycling in Yodo River estuary in Osaka Bay during August from 1991 to 2000 was analyzed by using the numerical ecosystem model and field observation data to clarify the reasons of change...
