...I. P. Holman; K. M. Hiscock; P. N. Chroston Abstract A study of the hydrogeological controls on the Pleistocene Crag aquifer in northeast Norfolk is reported. Geophysical methods, in particular multichannel seismic reflection profiling, have provided useful information on the internal structure...

...I. P. Holman; K. M. Hiscock Abstract Land drainage has caused a significant increase in surface water salinity in the River Thurne catchment of northeast Norfolk which is related to saline intrusion in the underlying Crag aquifer. A survey of surface water C1 concentration revealed values ranging...

..., it is deduced that most of the brackish water is of ancient marine origin but that there has been localized intrusion of modern seawater in coastal areas, especially around Ipswich. Saline water most probably entered the aquifer during Crag Group times (late Pliocene–early Pleistocene) and its chemistry has...

Low resistivity values observed in the Chalk are believed to be due to the presence of saline water in this important aquifer. This work was carried out...
