This paper reports a quasi 3D simulation in a curved river reach of The Yangtze River near The Huangshigang City, aiming to develop a numerical tool for modeling turbulent flows and pollutant transport in complex natural waters. The depth-averaged two-equation turbulence   model, together with   and   models, were used to close quasi 3D hydrodynamic fundamental governing equations. The discretized equations were solved by advanced multi-grid iterative method under coarse and fine two-levels’ grids. The processes of plume development, caused by the side-discharge from a tributary, also have been investigated numerically. The used three turbulence models are suitable for modeling strong mixing turbulence. The   model with higher order of magnitude of transported variable   provides a possibility to increase the computational precision. Based on the developed hydrodynamic model, a CFD software, namely Q3drm1.0, was preliminarily developed. This tool focuses on the refined simulations of the steady and unsteady problems of flow and transports with the strong ability to treat different types of discharges.
