Abstract
Large Eddy Simulation (LES) method for calculating the mixing process in the vicinity of a freshwater outfall in a coastal region has been developed. The LES calculation solves the three-dimensional non-hydrostatic equations of motion and is capable of directly representing the large-scale three dimensional fluid motion that is responsible for the mixing of the effluent and the ambient fluid. The present results indicate that the initial mixing of buoyant effluent can be reproduced fairly well for different discharge conditions, but the spatial extent and the time span of the simulation are limited to a few hundred meters in the horizontal direction and tens of minutes, respectively.
