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.

Discharge (L/s)

Flow (flow-through or/and recirculating)

Taxon and coverage of aquatic macrophytes

Sediment composition

Shading

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

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

Sediment of various compositions

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

Possible upon negotiation
