In each Demonstration Test Catchment, a range of experiments on working farms have been established. The project is using novel practices in water quality monitoring to help understand the processes in each catchment that give rise to the observed water quality. If you understand the system well enough then you can interpret changes in the water quality signal.
The monitoring system includes the establishment of a sensor web to control and interrogate instruments. Automated remote samplers and sensors are deployed throughout the sub-catchments with the associated telemetry. Large amounts of data are being generated which are being made available for all to use.
From 2013, assemblages of measures have been installed and are being tested for their effectiveness in improving water quality.
The Freshwater Biological Association, in partnership with Kings College, London, has set up a data platform to capture and store the hydrometric and water quality data.
Physical parameter being collected include rainfall, water levels and flows, turbidity, temperature, pH, conductivity & dissolved oxygen
The Role of the Data Archive
The Data Archive for the three DTCs will do three things. It will:
- receive data collected from the three test catchments.
- store the data in an Archive so that it is secure long after the research projects are complete.
- ensure that the data stored is easily accessible by all those with an interest in the catchments, including researchers, local residents, farmers, conservation groups, planners and policy makers.
The DTC Archive is being developed by the Freshwater Biological Association (FBA) and King’s College London (KCL). The FBA is experienced in environmental data archiving, while KCL has key skills in developing processes for handling and using electronic data. Click here to learn more
