Model studies of dispersion of pollutants in lake Vänern

Methods to compute dispersion of pollutants in a known velocity field is described. A Monte-Carlo or random walk technique is used in an example. The velocity field used is two-dimensional, constant in time, but the method can easily be used in a three-dimensional, time dependent velocity field.

A verification study (e.g. dye outlet in areal water body) is needed to prove the applicabilty of the method.
