This is a simple description. For detailed explanations see articles: Laser Diffraction-101 and -201. Particle Size Distribution (PSD) is a multi-parameter description of how the total concentration of particles is distributed into many size fractions....
Truly Portable Instrument Reduces Drilling Costs UPDATED 15 AUGUST 2017 The size distribution of drilling muds is frequently adjusted during the drilling process. As such, the particle size distribution must be measured frequently, several times a day....
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...
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...
Scintillation is what makes stars twinkle. It is what causes mirage in deserts or on hot surfaces. It is what causes shimmer underwater in the vicinity of hot vents in oceans. These effects result from temperature fluctuations in air or water. The same...
