Wave and current flume


Flume001The wave and current flume of the laboratory for physical geography is 18 m long, 0.40 m wide and 0.60 m deep. Waves are generated by a paddle that moves backwards and forwards. The maximum wave height is approximately 0.25 m. Steady currents can be generated in the flume, either alone, or with waves super-imposed. The current is driven by a pump with a maximum discharge of 0.15 m3/s at 1460 rpm that draws water from a settling well at the end of the flume through a recirculating pipeline to an opening with flow guide vanes in front of the wave paddle. The number of revolutions of the pump is controlled by means of a frequency converter which affords accurate adjustment of the water velocity.

Data acquisition and instruments

The data acquisition system includes 4 x CR10 data loggers with storage module and MD9 high speed serial interface. Instruments include capacitance wire wave height meters, electromagnetic flow velocity meters, optical backscatter sensors and pressure sensors. The connections are made through standard BNC connectors.


The flume is available for educational purposes and research. Secondary school experiments are free of charge. Academic research experiments are done at low costs. Please contact the laboratory for physical geography for rates.
