  1. Turbidity Monitoring During Port Dredging OperationsPort dredging keeps berths accessible, maintains navigation channels, and supports the movement of commercial vessels. It also disturbs bottom sediment,…
  2. Integrating Turbidity And Chlorophyll Sensors For Algal Bloom MonitoringAlgal blooms can change rapidly in response to sunlight, water temperature, nutrient loading, flow, and water-column mixing. A monitoring program that measures…
  3. How to Reduce Noise in Turbidity Data From Wave-Induced MotionTurbidity measurements collected in rivers, harbors, coastal zones, and dredging areas often contain rapid fluctuations that do not represent an actual change…
  4. Deploying Groundwater Profilers In Karst Aquifer SystemsKarst aquifers behave differently from porous, granular aquifers. Water can move through enlarged fractures, conduits, caves, and solution channels at speeds…
  5. Refractive Index and Optical Backscatter Sensor PerformanceOptical backscatter sensors estimate turbidity or suspended-solids concentration by transmitting light into the water and measuring the portion scattered back…
  6. Real-Time Suspended-Solids Monitoring in Industrial SlurriesIndustrial slurries can change concentration, particle size, viscosity, and flow behavior within minutes. In mineral processing, dredging, aggregate washing,…
  7. Selecting Reliable Turbidity Sensors for Hypersaline WaterHypersaline environments place unusual demands on turbidity monitoring equipment. Water with a very high dissolved-salt concentration can affect optical…
  8. Using Optical Backscatter to Estimate Bedload Transport in RiversBedload transport is the movement of sediment along or very close to a riverbed. Sand, gravel, and small cobbles may roll, slide, or bounce under the force of…
  9. Groundwater Profiler Data Quality Control For Reliable MeasurementsGroundwater profilers reveal how temperature, conductivity, turbidity, dissolved constituents, and suspended material change with depth. That vertical detail…
  10. Calibrating a suspended-solids sensor with site-specific sedimentA suspended-solids sensor estimates the concentration of particles in water by measuring how those particles interact with light. The instrument may report an…
