Groundwater levels data for the CEH River Lambourn Observatory at Boxford (01/02/2012 to 16/01/2015)

This dataset contains logged and manual observations of groundwater levels for piezometers at the Centre for Ecology & Hydrology (CEH) River Lambourn Observatory wetlands at Boxford, Berkshire, for the period February 1 2012 to January 16 2015 (01/02/2012 to 16/01/2015). The CEH River Lambourn Observatory located in Berkshire, UK (51.445o N 1.384o W) comprises c. 10 ha of riparian wetland which is bordered to the east by a 600 m stretch of the River Lambourn. The subsurface architecture comprises bedrock Chalk, overlain by gravels and then peat. Also presented are datums and ground levels for each piezometer, with data available for groundwater levels in peat, gravels and chalk. Groundwater heads were routinely checked at all piezometers by manually dipping observed water levels. At selected piezometers groundwater heads were monitored every 15 minutes using pressure transducers. Piezometers were not anchored to bedrock, though piezometer datum movement due to peat compressibility with saturation was discounted after comparisons of level surveys.
