Hydrogeological setting
This well monitors water levels in the Chalk of Wessex.
It is dug into the Lewes Nodular Chalk Formation. The site lies on the south side of the west-north-west–east-south-east trending Winterbourne Abbas Fault with a downthrow to the north-north-east of 20 m.
Well or borehole construction
It is a brick lined well, 1.4 metres in diameter. It was originally sunk for a farm water supply.
Hydrograph response
The hydrograph has an annual sinusoidal appearance, with some response to intense winter rainfall events. Its response is rapid for a chalk well, presumably because of its shallow depth. It appears to have an unconstrained response, although levels tend to peak close to 71 m AOD, and have only been lower than 64 metres on rare occasions.
