Two-dimensional depth-averaged phytoplankton growth modelling in the Rideau River (Black Rapids-Hog's Back reach)

Abstract

The present study was carried out to model the algal growth in Black Rapids-Hog's Back reach of the Rideau River. In this study a two-dimensional depth-averaged hydrodynamic model (HYDROSIM) and a transport model (DISPERSIM) both packaged in a GUI called MODELEUR were used. The model has been developed by Scientific Research Institute (INRS-EAU), Quebec. A model for growth and transport of algae was developed which was incorporated in the existing transport model, DISPERSIM. The simulated results of velocity vectors from HYDROSIM showed an agreement with the Acoustic Flowmeter For Remote Areas (AFFRA) measurements although the simulated values were always on the lower side. The modelling results of MIKE3D and a study carried out in 1997 support the results of the flow modelling in the present study. (Abstract shortened by UMI.)
