What is a SediMeter?

The SediMeter™ sensor consists of a vertical array of near-infrared optical backscatter detectors inside a narrow tube, inserted in the bottom of a water body, where it periodically measures a turbidity profile from below the bottom to above the bottom. By plotting the turbidity profile over time, the bottom processes are visualized: sediment accumulation, erosion, transport, anoxia, gas bubbles, near-bed turbidity, fluid mud, etc. The instrument also uses the turbidity profile to define an exact level of the bottom with a high resolution, 10 µm. This allows the detection of sediment transport even when there is no net change in level, since the addition and removal of individual sand grains in front of the sensor causes fluctuations in the level above the normal noise.
