DESCRIZIONE
Many laboratory experiments are based on the most faithful reproduction possible of a natural biotope. Benthic mesocosms reproduce the water region near the bottom, with the inhabitants that live there and their interactions. In tidal flats, the tide with its ebb and flow should be taken into consideration. In the prior art, an inverted tide simulation is carried out, in which the water height in a container is constant and a substrate platform with organisms is positioned at different heights with respect to the water, using a height-adjustable suspension device (06). A flow simulation is, however, not carried out. For this reason, the claimed device (01) comprises two flat pipe arrangements (13, 14) which are arranged along the fill height (04) of the water (20) on opposite sides (43, 44) of the container (02) and comprise flow openings (15) arranged opposite one another, wherein in a first control phase (I) of the control unit (12) water (20) is pumped into the one pipe arrangement (13) in order to simulate the flow behaviour during an ebb tide, and in a second control phase (II) water (20) is pumped into the opposite pipe arrangement (14) in order to simulate the behaviour during a flood tide, and wherein the height-adjustable suspension device (06) is synchronised with the control device (12) with respect to the simulation of ebb and flow.
