Kurzbeschreibung (Abstract)
We compare two semi-implicit models with topography-following coordinates for the solution of the shallow water equations. The models are identical in horizontal representation, but model A applies a vertical finite difference method and model B a vertical spectral method. Convergence, stability, and performance for different geometries and parameters are compared. We report our experiences gained in lake modelling with these models and give some results of simulations of Lake Ammer in the homogeneous and stratified cases. Different wave phenomena and the basin wide circulations will be discussed.
