Flood Plains
in North Wiltshire.
The biggest worry when buying a house is whether the property
lies on a flood plain. Many have witnessed the major floods
of
Tewesbury, Gloucestershire 2007, and the tragedies of Boscastle
and Carlisle in the early 21st century and it comes as a
relief
that Lyneham
does not
suffer
from
river
overspills.
This area forms a shoulder of land that divides the Avon valley
to the west from the lowlands of the River Marston tributaries
to the east. To the north, the scarp slope rises sharply from
the Avon valley and slopes more gently to the east around
Tockenham. To the south, the ridge narrows and slopes steeply on both
sides, terminating at the River Marden. The prominent scarp
slope rising from 60m AOD in the Avon Valley to 150m AOD
at Lyneham airfield, it reaches 128m AOD in the south around
Wick Hill. Lyneham being situated high on the chalk plateau
should not generally experience floods. See the Avon Vale
relief map to clarify the height pattern within our local
area more...
