In the Beryl Settings Manager, under Extras -> Water Effect -> Misc. Options, you can adjust the value of the water viscosity. At high viscosity, the waves can travel across the screen without being reduced much in amplitude; at low viscosity the waves are very quickly attenuated and do not spread far. However, this behavior is the opposite of the meaning of viscosity in fluid dynamics. If you drop a stone in honey (high viscosity) the waves will travel only a short distance before they disappear; if you drop a stone in water (low viscosity) the waves will travel much farther. The simplest solution would be to replace the water effect's "viscosity" with its reciprocal, which will correspond more closely to true viscosity. Perhaps there is a deeper confusion in the physics model though.
