Greater Manchester tackling increased flood risk with climate science
Greater Manchester has been working to counteract the increased flood risk exacerbated by climate change with a number of measures helping the rivers Irwell, Medlock and Roch to better contain water from the extreme rainfall.
A second flood basin was created upstream of Salford, on the site of the old racecourse in Castle Irwell, to store water from the River Irwell and prevent it flowing downstream and flooding properties in Salford, increasing the standard of protection to protect against a 1 in 100 year flood event for 1,900 homes and businesses. A pilot project was finished in 2014, to return the River Medlock to a more natural state following 100 years enclosed in a sterile red brick channel.
The River Roch, which had been hidden underneath Rochdale town centre for more than a century, was uncovered as part of a wider £250m regeneration programme. Despite high water levels following Storm Angus, the newly opened river mitigated the major damage that widely affected other parts of Greater Manchester, reducing flood levels and the duration by allowing overland flow to by-pass an upstream restriction from the culvert itself.
The Environment Secretary Andrea Leadsom MP on 24th November announced a £15m investment planned for natural flood management. “Natural flood management: slowing the flow and looking at ways to work with the contours of our environment to better improve protection is vital, and I can announce that we have been given a £15 million investment for further projects to be doing just that.”
Salford City Mayor and Chair of the Greater Manchester Low Carbon Hub, Paul Dennett said:
“Greater Manchester’s participation in the RESIN project is a unique opportunity for the region to participate in cutting-edge climate science, research into critical infrastructure protection, adaptation development while reaping immediate benefits for its citizens.
“These three projects demonstrate the different ways on how we can start to protect our towns and communities from flooding by opening up culverts and using regeneration that also benefits the appearance and natural eco systems of our waterways.”
