Half a year after our original spot survey in Suffolk, when we measured the flow of a small stream to support an abstraction licence for winter abstraction. The client has been encouraged by the initial results to carry out more extensive monitoring over the winter period to support their abstraction licence with the Environment Agency. Exo was contracted to provide 5 months’ worth of monitoring data at 2 stations, using pressure sensors and flow velocity meters. The Solinst pressure sensors constantly monitor the water level in the stream over the whole winter with 0.01m accuracy.
These were mounted in scaffold tubes and carefully fixed in the stream. The flow velocity shall be obtained with a Valeport 801 at specific intervals during the monitoring period, to match the fluctuating water levels.
We are monitoring the weather forecasts to monitor the stream at high flow events. These stormy downpours (the kind that makes you question getting out of the house in the first place) will give us the range of flow events that we required to accurately predict the amount of water available throughout the winter abstraction period. Effectively, we are now storm chasers, so watch this space for further updates!
