Plans to build major flood defences in an area of Nottingham have been withdrawn by the Environment Agency because they are "inadequate".
New research revealed there was an increased risk of flooding in Attenborough since plans were drawn up.
The planned defences along the Strand will now be raised by 0.5m (1.6ft).
New proposals will be submitted to Broxtowe Borough Council in spring 2008 and construction is expected to start later that year.
Area flood risk manager, Paul Lockhart, said: "It is important to ensure that we provide the most effective flood protection to the people of Attenborough, and to Nottingham itself.
"So we need to re-assess our proposals in the light of what this new model is telling us about the increased risk... we are confident once it is reviewed, the design will use the best available information and we will not need to review it again."
