In this research you can find things regarding concentration data, measurements, laser, and point measurement. This research contains information about measurement, emporal resolution, and concentration.
There are lots of information regarding range, resolution, and laser based sensors are described inside the research. Here are chosen from this research:
High-resolution monitoring of sand mass balance in the Colorado River below Glen Canyon Dam, Arizona, USA, is needed for environmental m anagement. In the Grand Canyon, frequent collection of suspended-sediment samples from cableways is logistically complicated, costly and provides limited spatial and temporal resolution. In situ laser sensors were tested in the Colorado River as an alternative method for monitoring the river’s suspended transport. LIS ST data were collected at a fixed-depth, near-shore site while isokinetic measurements were simultaneously made from a nearby cableway. Diurnal variations in LISST grain size and concentration data compared well with depth-integrated, cross-section data. The LISST was also successfully used to electronically trigger an ISCO 6712 pump sampler to provide contin uous monitoring during periods when suspended concenfrations exceeded the L ISST’s measurement range.
Also, the research tells us information around laser transmission, samples, and sensors.
