vi. THE UNDERGROUND WATER OF 

 NOTTINGHAMSHIRE

The accompanying map shows broadly the travel of water underground 

 in the Bunter Sandstones and Pebble Beds of Nottinghamshire. The 

 contours are related to feet above sea level or ordnance datum and are 

 based on the many records published in the Water Supply Memoir of 

 Nottinghamshire of H.M. Geological Survey, including the top portion 

 in the neighbourhood of Bawtry and East Retford worked out by 

 Dr. Bernard Smith. 



The surface configuration does not appear to affect the general direction 

 of flow in minute detail, but from the broad standpoint the underground 

 water level does follow the surface configuration, the slope of which 

 generally varies from north-east to south-east; north-east towards Retford 

 and east between Tuxford and Southwell under the Keuper Marl where 

 the water tends to become saUne, and south-east between Southwell and 

 Nottingham. The highest underground levels appear to be in the neigh- 

 bourhood of Mansfield where the contours would merge into the under- 

 lying Magnesium Limestone. Rivers such as the Poulter and Meden tend 

 to flow in the same direction as the contours.
