A study has been launched to identify the sources of flood risk on the River Ouseburn in Newcastle.
The research is part of a Defra programme looking at the links between drainage systems and river levels.
The Environment Agency is leading the study with partners including Northumbrian Water, Newcastle University and Newcastle City Council.
The Ouseburn drains northern suburbs of Newcastle into the River Tyne and has caused flooding problems in the past.
Environment Agency project leader Richard Robinson said: "There is no one solution that can alleviate flood risk.
"But by working on a joint approach it is hoped that we can learn more and then implement changes to minimise flood risk in the area."
A series of public meetings is being arranged to keep local residents and businesses informed.
