OTT Hydromet Helps Improve the Management of the Longford River in the UK

OTT Hydromet Helps Improve the Management of the Longford River in the UK

Video, Water Flow, Water Level, Water Quality
  VINCI Facilities in the UK, manages around 37,000 assets in the Royal Parks (such as fountains, statues and royal memorials for example in Kensington Gardens) and the water features are fed by the Longford River. If you have ever travelled in west London, there is every likelihood that you have crossed the Longford River – probably without realizing it. Built for King Charles I in 1638/39, the river travels from near Heathrow airport to feed the water features in Bushey Park and Hampton Court Palace. Maintenance and ongoing management of the Longford river are required as it helps protect industrial and residential areas, which the river passes through, from flooding and helps preserve the ecological status of the river. Checking the status of the Longford River used to be…

Fact Sheet: Turbidity Measurement – A Simple, Effective Indicator of Water Quality Change

Fact Sheet: Turbidity Measurement – A Simple, Effective Indicator of Water Quality Change

Fact Sheet, Surface Water, Water Quality
Download the Fact Sheet Now! The amount of dispersed suspended solids in natural water bodies is an important indicator of water quality. These solids that often include silt, clay, algae, organic matter, and other minute particles, obstruct the transmittance of light through the water and impart a qualitative characteristic known as turbidity. Turbidity is often closely correlated to climatological or surface water conditions and changes in turbidity are therefore indicators of changes in environmental conditions. “Turbidity data can be used as a surrogate measurement because it is strongly correlated with sediment, nutrients and bacteria, and can be measured in-stream on a continuous basis.” Topics Discussed in Fact Sheet: Turbidity Measurement Technologies Common Turbidimeter Design Criteria Variability Based on Measurement Method Download the Fact Sheet!

Case Study: Measuring Nitrate in Puget Sound Using Optical Sensors

Case Study, Sensors, Water Quality
Download the Case Study Now! Learn how the King County Dept. of Natural Resources and Parks in Seattle, Washington conducts long-term marine monitoring to assess baseline conditions and trends in Central Puget Sound, especially nitrate. In this case study, Sea-Bird SUNA measurements from Puget Sound, corrected for bromide, match the accuracy of measurements made with traditional wet chemistry techniques to within ±0.0025 mgN/L. About Sea-Bird SUNA V2 The SUNA V2 is the ultimate solution for real-time nutrient monitoring. This sensor measures nitrate with industry leading accuracy and stability over a wide range of environmental conditions (including extremely turbid and high CDOM conditions), from blue-ocean nitraclines to storm runoff in rivers and streams. The SUNA V2 incorporates the proven MBARI-ISUS nitrate measurement technology, which is based on the absorption characteristics of nitrate in…

Measuring water level in open channels, rivers, reservoirs, and lakes is one of the foundations of hydrological monitoring and has been a focus of OTT Hydromet since its first current meters were designed in 1875. For water level and depth measurement, no application is the same. For this reason, OTT Hydromet provides a variety of sensors with different measurement principles, tailored to fit the specific requirements of different hydrologic measurement sites, including: High concentrations of suspended sediment Flashy sites Presence of ice Lightning prone Unstable stream banks Shallow water or narrow channels Want to learn more about the differences in technology and which sensor fits your application?

Case Study: Long-Term Water Quality Monitoring with the Sea-Bird HydroCAT-EP

Case Study, Water Quality
Download the Sea-Bird HydroCAT-EP Case Study Now! The Sea-Bird Scientific HydroCAT-EP is ideally suited for extended deployments in remote, biologically rich environments. Factory calibrated, field proven sensors ensure long term data stability. Depending on the application, the HydroCAT-EP can collect high quality data for several months up to a year. As part of HydroCAT-EP field tests, an extended deployment was carried out at Shilshole Bay, Puget Sound, Washington. In conjunction with the field tests, an SBE 37 MicroCAT with Dissolved Oxygen was deployed and a water sampling program was conducted. Intercomparisons between the data sets show the HydroCAT-EP is an accurate and stable instrument. These results also highlight the lack of maintenance required to sustain high quality data return. The HydroCAT-EP was deployed for 3.5 months from July 1, 2015…
