- Groundwater profiler deployment in wetlands for exchange measurementWetlands are active boundaries between aquifers, soil, surface water and the atmosphere. Water may enter from a shallow groundwater lens, move laterally…
- Turbidity Monitoring for a Pipeline River CrossingA pipeline crossing can disturb the bed and banks of a waterway, releasing fine sediment into the flow and creating a visible plume downstream. For an…
- Optical Backscatter Profiling for Near-Bed Sediment GradientsSediment concentration rarely remains uniform through the water column. Close to the bed, waves, currents, vessel movement and river discharge can lift fine…
- Building A Reliable Long-Term Turbidity DatasetLong-term turbidity monitoring supports decisions about dredging, catchment health, mine-water controls, river restoration and marine construction. A dataset…
- Continuous bathymetric sediment mapping with turbidity sensorsIntegrating turbidity and depth sensors for continuous bathymetric sediment mapping creates a more complete picture of how underwater terrain changes. A depth…
- Using Turbidity To Evaluate Light Availability For Submerged PlantsSubmerged aquatic vegetation depends on sufficient light reaching leaves below the water surface. When suspended sediment, plankton, organic particles, or…
- Mapping Salinity Gradients In Brackish AquifersBrackish aquifers contain a mixture of fresh and saline groundwater, often with sharp chemical transitions over relatively short vertical distances. These…
- Deploying Optical Sensors on Trawl-Resistant Bottom MountsCoastal waters are productive, dynamic, and heavily used. Commercial fishing, dredging, shipping, construction, aquaculture, and environmental research can all…
- Turbidity Monitoring Strategies for Combined Sewer Overflow DetectionCombined sewer overflows (CSOs) occur when a shared pipe network carries more stormwater and wastewater than a treatment plant or collection system can manage.…
- Field Calibration Of Suspended-Solids Sensors Without FormazinReliable suspended-solids measurements begin with a calibration method that reflects the sensor, the water, and the material being measured. In a laboratory,…
