- Integrating Suspended-Solids Sensors in Tailing Dam Early WarningIn the red dust of the Pilbara and the lignite-rich valleys of the Hunter, Australian mining operations face a quiet but persistent hazard: the slow, sometimes…
- Real-time water quality data and the ethics of transboundary sharingRivers are indifferent to borders. A drop of water entering the headwaters of a tributary in one jurisdiction will, given enough weeks, flow past the farms,…
- Validating Optical Suspended-Solids Sensors in High-TDS WatersOptical suspended-solids sensors are popular for continuous monitoring, but total dissolved solids (TDS) introduce scattering bias and refractive confusion…
- Beneath the Water Table: Profiling Groundwater at SVE SitesA soil vapor extraction system looks deceptively simple from the surface: an array of extraction wells, a blower skid, a stack of pipework, and a process skid…
- Using suspended-solids data to guide delta habitat restorationAustralia's river deltas sit at a crossroads of competing pressures. The wetlands where the Murray meets the Southern Ocean, the mangrove-fringed estuaries…
- Practical Repairs and Spare Parts for Aging Turbidity StationsThe Murray-Darling Basin, the hydro storages dotted across Tasmania's central highlands, the wet-dry tropics of the Top End, and the estuaries fringing the…
- Multi-beam optical sensors for monitoring dense suspensionsIndustrial operators, environmental scientists, and harbour authorities share a stubborn problem: how to measure what is happening inside water loaded with…
- Optical Backscatter Techniques for Ice-Covered Lake Sediment PlumesWhen a winter ice lid seals a lake from the wind, the water column beneath undergoes changes that are difficult to observe directly. Sediment disturbed by…
- Estimating Fine Sediment Load from Optical Turbidity and Acoustic Doppler DataFine sediment load is the invisible currency of catchment health. Every gram of silt and clay that moves past a monitoring station in the Brisbane River, the…
- Sensor Network Design for Granular Sediment TransportGranular sediment transport in alpine rivers is governed by short, energetic events rather than a steady background process. Snowmelt, intense summer rainfall,…
