With financial support by the German Research Association (Deutsche Forschungsgemeinschaft) an instrument for automatic long-term measurement of suspended matter has been developed by the authors. It works on a settling method. A sample of 20 1 of water is pumped into a conical settling bottle every hour. The suspended sediments settling in a measuring tube at the bottom of the bottle are recorded by a camera. The device called "Silt Gauge" is intended for long-term measurements in shallow coastal water.
