- Using Suspended-Solids Sensors to Monitor Construction RunoffConstruction sites can release fine sediment whenever soil is exposed, stockpiles are disturbed, or rainfall moves across recently graded ground. The resulting…
- Extracting settling velocity from optical backscatter dataOptical backscatter (OBS) instruments estimate suspended sediment concentration from the light scattered by particles in water. When a sediment pulse settles,…
- Why sampling volume matters in turbidity sensor designTurbidity is often treated as a simple measure of how cloudy water appears, yet a turbidity sensor does not measure an entire water body. It measures the light…
- Groundwater Profilers Reveal Submarine Spring Discharge In HawaiiSubmarine groundwater discharge is easy to overlook because much of it occurs below the waterline, where fresh groundwater mixes rapidly with seawater. Around…
- Field observations of suspended solids where rivers meet the seaWhen a river enters the coastal ocean, suspended sediment rarely forms a uniform cloud. Freshwater, clay, organic particles and sand are carried into a moving…
- Validating In-Situ Optical Data With Field Sediment ChecksOptical turbidity and suspended-solids sensors provide continuous information that a bottle sample or visual inspection cannot match. Installed in a creek,…
- Designing Suspended-Solids Feedback for Dredge ControlAutomatic dredging systems increasingly use optical measurements to control production rate, pump output, cutter speed, overflow behaviour, or vessel movement.…
- Managing Air Interference in Optical Solids MonitoringOptical suspended-solids instruments are widely used in wastewater treatment because they provide rapid, continuous information without the delay of laboratory…
- Verification of Turbidity Sensor Linearity Using Dual Standard Dilution SeriesA turbidity sensor is often described as linear when its output rises in proportion to the concentration of suspended material. In practice, that assumption…
- Choosing Optical Sensor Housings for Extreme Water ChemistryOptical instruments used in dredging, hydrology, environmental research and industrial monitoring can encounter water far outside the neutral range. Acid…
