The EA view on dredging (dated 2010)

Posted on January 24, 2024January 24, 2024 by ecwlarcombe

Extract from source document  Lower Thames Flood Risk Management Strategy

Summary of comments and responses to consultation (2010)


Lower Thames Strategy Response: Bathymetric surveys of the river bed have been
carried out over the past few years and have provided evidence of the dynamic erosion
and deposition of sediment within the River Thames. These bathymetric surveys have
shown that historical dredging only increases channel capacity temporarily as the River
Thames silts up again and this is before climate change is taken into account. Dredging
does not provide sufficient capacity to reduce flood flows due to the huge volume of water
that occurs during a flood. Due to the difficulties and expense of removing and disposingof contaminated dredged material from the River it has been set aside as an option under this Strategy. Bathymetric surveys and modelling will continue to inform our River management.

DATCHET

The name "Datchet" is thought to be Celtic in origin, and the last part may be related to cet ("wood"). In the Domesday Book it is called "Daceta".lla. Datchet is first mentioned between 990 and 994, when King Ethelred made small grants of land here.

HORTON

The village name "Horton" is a common one in England. It is Old English in origin and derives from the two words horu 'dirt' and tūn 'settlement, farm, estate', presumably meaning 'farm on muddy soil'.In the Domesday Book of 1086 it was recorded as Hortune.

WRAYSBURY

The village name was traditionally spelt Wyrardisbury; it is Anglo Saxon in origin and means 'Wïgrǣd's fort'. Its name is recorded in the Domesday Book of 1086 as Wirecesberie and as Wiredesbur in 1195. The name is seen again as Wyrardesbury in 1422.
