The construction information and research body is receiving support from the Environmental Agency, Defra, and the DCLG.
CIRIA has launched an information network on flood risk and surface water management.
The support services consultant has launched the Local Authority Network for Drainage and Flood Risk Management (Landform) for companies that are working with local authorities to tackle flooding risks.
Landform is to be managed by the member-based construction information and research body, with support from the Environment Agency, Defra, and the DCLG. It allows companies to share information, identify common problems, and work out solutions through a central website and a series of events.
Steve Williams of the Planning Officers Society said: "Landform provides the ideal mechanism to facilitate communication between those that work in and with local authorities, helping them get to grips with the challenges of flood risk management in a changing climate.”
The first event, titled Delivering Sustainable Drainage on the Ground, will be held in London on 20 September.
