Abstract
A new laboratory for long-term experimental studies in running water has been installed in the Limnologische Flußstation, Schlitz, Germany. Water from the River Schlitz can be deflected into a set of four experimental cannels, each 4 m long; rate of flow, volume and substratum can be varied, and factors such as temperature and the concentration of dissolved substances can be maintained at a constant level. The equipment is described and mathematical characteristics of the respective current conditions are given.
