Last updated: 11 May 2016 Turbidity as a surrogate for suspended sediment concentration (SSC) is commonly used and deeply established in practice. The shortcomings of turbidity as a surrogate for SSC are: The calibration changes with grain size; The...
LISST-Infinite installed next to a draft tube. Sequoia’s LISST-Infinite instrument is made to protect turbines by sounding alarms so that plant operators may decide to shut down power production and save turbines from abrasive damage. The...
[Readers should be aware that due to the different nature of size dependence of optical and acoustic backscatter sensors, changes in grain size distribution can cause the two data to not track. Neither sensor holds calibration with changing grain size....
Waterways, Maintenance Dredging, and Contaminated Sediment Removal Dredging is essential for creation or maintenance of navigation channels, as well as for removing contaminated sediments. The contamination of water by dredged sediments is regulated...
The LISST-ABS would reveal rich sediment structure that turbidity misses. For measuring suspended sediments, the use of optical backscatter sensors or other turdibity sensors is widespread. At the same time, it is understood that these sensors respond...
