Turbidity shows no response to large particles, gets concentration wrong [Sequoia, January 09, 2013] The use of turbidity sensors is widely prevalent in the sediment community. The common practice is to calibrate the turbidity meter...
Updated 29 April, 2016 The loss of accuracy, i.e. error in concentration can be caused by a number of factors. Overall, the accuracy of LISST instruments is demonstrated by this vertical profile taken in a river by USGS scientists. The black points are...
