Swedish cities need to prepare for future water flows

As part of the EU-funded

GreenClimeAdapt

project, IVL Swedish Environmental Research Institute is studying the potential effects of high water flows and more intensive rain on Swedish cities, and examining how built-up areas can prepare themselves to deal with high water flows in the future.

In a future climate scenario, high water flows and intensive rain will increase the load on surface water drainage systems and urban watercourses in many Swedish cities. Given the acute need for action to deal with this problem in a number of cases, IVL is evaluating the effects of suitable measures in the city of Malmö as part of the GreenClimeAdapt project with the aim of alleviating the risks presented by high water flows in the future.
 
As part of the project, the City of Malmö is implementing a number of actions to reduce its future water loading, including the installation of green roofs and the provision of dams. IVL is examining these measures and scaling them up as part of future scenarios that will also include major areas of eastern Malmö. Modelling is then employed to analyse the potential effects of these more comprehensive scenarios on water flow during periods of intensive rain, and on the risk of flooding and erosion damage in the Riseberg Brook flowing through the east of the city.
 
It is hoped to develop a methodology for evaluating proposals to alleviate future surface water drainage problems in cities other than Malmö.
