Description of Facility

The stream mesocosm facility at the Landau Campus (SW Germany) consists of 16 independent high-density concrete stream channels (each channel: 45 m length, 0.5 m depth; 0.4 m width). The channels can be run in a flow-through or recirculating mode with discharges up to about 3 L/s representing flow conditions and hydraulic residence times as typically represented by scenarios used e.g. for the regulatory assessment of chemicals in Europe.

Controlled Parameters

Discharge (L/s)

Flow (flow-through or/and recirculating)

Taxon and coverage of aquatic macrophytes

Sediment composition


Exposure scenario (peak-, hour- and day-scale)

Research Topics

Environmental fate of pollutants (e.g. sorption transient storage and longitudinal dispersion)

Assessment of adverse effects of pollutants on macroinvertebrates following pulse exposures

Evaluation and establishment of aquatic-terrestrial model ecosystems to assess aquatic insect emergence-related pollutant transfer or effect translation from aquatic to adjacent terrestrial systems

Facility location(s)
Primary interests
Specialist areas

Sediment of various compositions

Aquatic macrophytes (e.g. Elodea nuttallii, E. canadensis, Myriophyllum spicatum)


Possible upon negotiation
