- Groundwater Profiler Deployment In Unconsolidated SedimentsGroundwater profiling in sand, silt, gravel, and mixed alluvial deposits can reveal chemical, hydraulic, and sediment-related changes that fixed monitoring…
- Choosing Optical Wavelengths For Suspended-Solids MonitoringSuspended-solids monitoring depends on how particles scatter and absorb light, but the water surrounding those particles matters just as much. Clear water,…
- Using Turbidity Data to Validate Coastal Hydrodynamic ModelsCoastal hydrodynamic models help explain how currents, tides, waves, and river discharge move water and suspended material through estuaries, harbors, lagoons,…
- Comparing Field and Laboratory Measurements of Total Suspended SolidsTotal suspended solids (TSS) measurements describe the mass of particulate material carried by water. The result is commonly reported in milligrams per liter…
- Optimizing Sensor Sampling Intervals for Dredging Plume TrackingDredging can generate suspended sediment plumes that change rapidly near the cutter head, draghead, overflow, or discharge point, then spread and dilute as…
- Managing Calibration Drift In Optical Water-Quality SensorsOptical sensors provide a practical way to measure turbidity, suspended solids, and related water-quality conditions in real time. By transmitting light…
- Mapping fracture zones in bedrock with groundwater profilersFractured bedrock can store and transmit groundwater through narrow, discontinuous pathways that are difficult to identify from surface geology alone. A…
- Automated Cleaning for Reliable Turbidity Monitoring in Eutrophic WatersLong-term turbidity monitoring becomes substantially more difficult when water contains high concentrations of algae, organic debris, and dissolved nutrients.…
- How Particle Size Shapes Optical Backscatter MeasurementsOptical backscatter sensors estimate suspended material by transmitting light into the water and measuring the portion scattered back toward a detector. The…
- Deploying A Real-Time Suspended-Solids Network In A Large River BasinA large river basin can carry sediment from upland streams, agricultural land, construction sites, mines, reservoirs, and floodplains. Concentrations may…
