Monitoring Ground Water Levels
Our MP dips a Piezometer! |
Eleven 4-5 metre deep piezometers have been installed along the
main route and monitoring continues using a purpose built reel and sensor device. |
Ground Water Data |
Boreholes (piezometers) were drilled into the ground adjacent to the stream to allow monitoring
of groundwater levels. The 11 boreholes are measured ('dipped') each month using a special reel
and sensor. In addition, 8 readings are taken of the surface water level at points adjacent to
the boreholes.

Water Levels and Piezometer Data |
The graph below clearly shows the channel gradients (falling over 1 metre between Town Moor and Green Lane) and how stream and ground water levels change along the route. The full data will help our professional advisers to understand the stream hydraulics, linkages between rainfall, stream and groundwater levels - and in particular the likely impact of our proposed changes to the channels.
