- Reading Tidal-Flat Sediment Movement Through Optical MonitoringTidal flats can look calm from the shoreline while carrying large amounts of sediment through shallow channels, pools, and exposed intertidal surfaces. Each…
- Temperature Effects in Optical Turbidity MonitoringOptical turbidity instruments estimate water clarity by measuring how suspended particles scatter or absorb light. The resulting signal is commonly reported in…
- Deploying Turbidity Sensors From Small Unmanned Surface VesselsSmall unmanned surface vessels (USVs) give environmental teams a practical way to measure water quality across shallow, hazardous, or difficult-to-access…
- Data Archival and Metadata Standards for Long-Term Water Quality MonitoringLong-term water-quality programs generate far more than streams of turbidity, suspended-solids, temperature, or conductivity values. They produce a record of…
- Optical Sensor Response to Mixed Clay And Sand SuspensionsWater containing suspended clay and sand can produce a turbidity signal that is difficult to interpret with a single calibration or a simple assumption about…
- Using Groundwater Profilers to Assess Aquifer HeterogeneityAquifers are rarely uniform bodies of sand, gravel, or fractured rock. Layers with different grain sizes, permeability, porosity, chemistry, and recharge…
- Suspended-Solids Monitoring for Cleaner, More Reliable Cooling Water IntakesCooling-water systems depend on a steady supply of water with predictable physical and chemical characteristics. When rivers, estuaries, reservoirs, or coastal…
- Integrating turbidity sensors for spatial plume mappingDredging, construction, storm runoff, and sediment transport can create plumes that change rapidly across both distance and depth. A single turbidity sensor…
- Turning Optical Backscatter into Reliable Sediment Time SeriesOptical backscatter sensors provide a fast way to observe changes in suspended sediment concentration. Instead of collecting a water sample every few hours, an…
- Designing a turbidity monitoring plan for marine construction projectsMarine construction can disturb seabed sediments, release suspended solids, and create a visible plume that moves well beyond the immediate work zone.…
