The Geology Of The Severn Barrage Area
Green, G. W.
Fletcher, B. N.
The offshore geology in the area of the Severn Barrage scheme is not known in detail, but the rock types are the same as those that occur in the adjacent land areas. The onshore geology, which is well known, is very relevant to the barrage scheme and is discussed first. Much of the work included in this report is based upon recent work by the Institute of Geological Sciences (IGS) and has not yet been published.
