obstacle; groundwater flow
towards a lake
lines represent streamlines. Here, baseflow is in vertical direction towards a circular
lake, where a constant potential (water table) is given (Strack
1989
).
White lines are the potential contours. Streamlines are depicted in black. The
interior of the lake, within the white circle, has to be neglected in the groundwater
flow problem.

15.4 Example: Vortices or Wells Systems
As an example for the various applications of analytical solutions for the com-
plex potential an M-file is developed, by which systems of several vortices or wells
can be evaluated and illustrated. Moreover, various types of boundaries can be
considered, here as example along the x- or y-axes. The input section of the file is
as follows:
