- How to Choose Between a Nephelometer and a Turbidimeter for Regulatory ComplianceSelecting an optical instrument for water-quality monitoring is rarely a matter of choosing the device with the lowest quoted turbidity range. A nephelometer…
- Groundwater Profiling For Mine Pit Lake Remediation In AustraliaAbandoned and operating mine pits can fill with groundwater, rainfall and surface runoff, creating lakes whose chemistry changes with depth and season. A pit…
- Deploying Turbidity Sensors on Drifting Buoys for Spill TrackingWhen a sediment plume, chemical release, or dredging disturbance moves through a waterway, fixed monitoring stations can miss the most important part of the…
- Turbidity Effects on Dissolved Oxygen Measurements and CorrectionDissolved oxygen (DO) is a key indicator of aquatic health, wastewater performance and habitat suitability. Yet a DO value can be misleading when the water…
- Protecting Optical Profilers in Deep Australian WatersDeep-water profiling systems operate where access is limited, pressure is high and a small maintenance fault can compromise an entire survey. Optical sensors…
- Data synchronisation techniques for multi-sensor turbidity networksA multi-sensor turbidity network turns scattered optical measurements into a view of how sediment moves through a river, estuary, dredging zone, or coastal…
- Using Groundwater Profilers To Investigate Hyporheic Exchange In RiverbedsRiver water does not move only downstream at the visible surface. Some of it enters the porous sediments beneath and beside the channel, travels through…
- Turbidity sensor response to varied sediment mineralogyTurbidity sensors are often treated as straightforward instruments: suspended particles scatter light, the detector measures that scattered light, and the…
- Real-Time Suspended-Solids Monitoring for Cooling Water IntakesIndustrial cooling systems depend on a stable flow of clean water. When a river, estuary, harbour or ocean intake carries elevated suspended sediment, the…
- Selecting anti-fouling coatings for optical sensor windows in tropical watersOptical instruments deployed in tropical rivers, estuaries and coastal waters face a demanding combination of heat, sunlight, nutrients and biological…
