- Real-Time Suspended-Solids Data For Smarter DredgingDredging changes the distribution of sediment in the water column from minute to minute. Cutter-head position, pump rate, tidal currents, vessel movement, and…
- Delineating Contaminant Plumes With Groundwater ProfilersGroundwater contamination rarely follows a clean, predictable boundary. Dissolved chemicals move through layers with different permeability, while pumping,…
- Optical Sensing Strategies for High-DOC WatersOptical instruments are widely used to measure turbidity, suspended solids, and sediment transport in rivers, reservoirs, estuaries, coastal zones, and…
- Designing a low-power turbidity station for solar-powered remote monitoringA remote turbidity station must deliver trustworthy water-quality data while operating for weeks or months without mains electricity. That requirement changes…
- Single- and Multi-Wavelength Turbidity Sensor LimitsTurbidity sensors estimate the cloudiness of water by measuring how suspended particles interact with light. The result is commonly reported in nephelometric…
- Integrating Turbidity and Acoustic Doppler Sensors for Sediment Flux EstimationSediment flux estimation becomes far more reliable when optical turbidity measurements are paired with acoustic Doppler observations. Each sensor describes a…
- Groundwater Profilers In Fractured Rock Hydrology StudiesFractured rock aquifers rarely behave like uniform porous media. Groundwater may move rapidly through a small number of connected fractures while adjacent rock…
- How Turbidity Monitoring Supports Ballast Water ComplianceBallast water is essential for vessel stability, trim, and safe operation, yet its transfer between ports can move organisms and suspended material across…
- Deploying suspended-solids sensors for erosion monitoring on construction sitesConstruction activity can change the movement of sediment through a watershed within hours. Clearing vegetation, grading slopes, excavating foundations,…
- Correcting turbidity data when bubbles disrupt high-energy flowsTurbidity sensors are often deployed where water is moving rapidly: below dredge heads, near propellers, in spillways, around hydraulic structures, and in…
