Numerical Simulation of Mixing in Natural Rivers
A numerical model is developed for two-dimensional transient mixing in natural river channels. Through the use of an orthogonal curvilinear coordinate system based on the geometry and the flow distribution of the river channel, the physical domain is mapped into a rectangular strip by introducing the cumulative discharge as the new transverse coordinate. The concentration values at each point in the grid system are then determined at time levels by using a combined implicit/explicit finite difference successive scheme. A computer program is developed to solve these equations, and a case study is presented and verified with an existing steady-state analytical solution and field measurement.
