- Monitoring turbidity downstream of a hydropower dam during flushing eventsFlushing a hydropower reservoir can restore storage capacity, clear deposited sediment from near-intake areas, and improve the long-term operation of a dam. It…
- Deploying Groundwater Profilers in Intertidal ZonesSubmarine groundwater discharge (SGD) is the movement of groundwater from the seabed or shoreline into coastal water. It can carry freshwater, dissolved…
- How Salinity Affects Optical Turbidity Sensor CalibrationOptical turbidity sensors are often deployed across water bodies where dissolved salts, suspended particles, temperature, and biological activity change over…
- Optical Backscatter for Sediment Estimates in Retention PondsStormwater retention ponds capture runoff, slow drainage, and allow suspended particles to settle before water leaves a developed site. That same settling…
- Turbidity Sensor Cross-Calibration Across Instrument ModelsTurbidity sensors from different manufacturers, product families, or production generations can report different values while observing the same water. This…
- How to Determine Optimal Sampling Frequency for Turbidity in Flashy StreamsFlashy streams can shift from clear, low-flow conditions to sediment-laden torrents within minutes. A turbidity monitoring program that samples too slowly may…
- Groundwater Profiling for Managed Aquifer Recharge MonitoringManaged aquifer recharge (MAR) basins are designed to move surface water into an aquifer through engineered infiltration. Their value depends on what happens…
- Effects Of Air Bubbles On Submersible Turbidity MeasurementsSubmersible turbidity sensors provide valuable continuous data in rivers, reservoirs, coastal waters, dredging zones, and treatment facilities. Their optical…
- Standard Procedures for Optical Sensors on Buoy PlatformsOptical sensors mounted on buoys provide continuous measurements of turbidity, suspended solids, sediment plumes, and related water-quality conditions. They…
- Selecting turbidity sensors for freshwater and marine environmentsTurbidity monitoring looks simple until a sensor is moved between rivers, lakes, estuaries, coastal waters, and active dredging zones. The same optical…
