A flooding threat facing up to 1,000 properties in Nottinghamshire is to be investigated by the Environment Agency.
Surveyors from the agency will assess the risk to properties in nine villages and then decide how to protect them.
They include Radcliffe on Trent, Burton Joyce and Gunthorpe which cannot be protected by large schemes like the ones protecting Nottingham itself.
Ground levels will be measured by computers and the information used to apply for funding for defences.
Surveyors will use satellite mapping technology to measure the elevation of houses and villages and then compare this with their records of flooding levels.
Over the next six years, they will identify where they can carry out work to reduce the flooding risk
