  author={Thomas F. Russell},
Abstract : The common "folklore" that Eulerian-Lagrangian methods performs better (are more accurate) with large Courant numbers (large time steps) than with small Courant numbers, due to numerical dispersion in the latter case, is explained theoretically A formulation that does not suffer from large numerical dispersion for any Courant number is outlined.
