Title: Ipswich flood defences
Author: National Rivers Authority Anglian Region
Document Type: Monograph
Abstract:
This brief NRA leaflet describes the Ipswich flood defences. There has been a long history o f flooding in Ipswich, and records show significant flooding on 14 occasions due to tidal surges and on four occasions due to river flooding. The flooding of 100 hectares of urban area in 1953 affected 700 residential and more than 580 commercial and industrial properties, whilst in 1939 the river flood affected about 3,000 residential properties. The flood defence scheme is based on two main criteria: firstly that the defences should be capable o f withstanding a high tide similar to January 1953 and secondly, that the channel should be capable of dealing with flow approximately equal to the last two major floods of 1939 and 1947. Construction work started in 1971 and took twelve years to complete.
