Abstract

Wind induced horizontal transport phenomena have been analyzed in shallow lakes with a coupled two dimensional circulation fluid element tracking model. Advective currents are calculated by a depth integrated ADI type finite difference model. In subdomains the influence of small scale bottom topography on the velocities is taken into account by local grid refinement. To avoid numerical diffusion and to obtain qualitative results fast and easily, transport simulation is based on the Lagrangian Fluid Element Tracking method, modelling the paths of marked fluid elements in the advective diffusive velocity field.
