The Hebden Bridge Picture House will screen a short film which investigates the cause of the Boxing Day floods.
The film has been made by Hebden Bridge floods campaigner Barry Greenwood and agricultural engineering adviser and documentary producer Anthony Milroy.
The film’s director Nick Wilding said: “It looks at what happened on Boxing Day and investigates why the depth of those floods were directly related to the failure of the Environment Agency to fulfil their statutory obligation since 2010 to maintain the river bed and its banks.
“It makes a desperate plea for members of the Environment Agency to stop refusing to remove the vast piles of rubble and silt from the catchments, where the Calder and Elphin Brook collide in Mytholmroyd and where the Calder and the Hebden collide in Hebden Bridge.
“This is because there was greater rainfall in 2012 than in 2015 and there is a grave danger that there will be another flood even higher than the Boxing Day very soon and it could easily be even higher than the last if they don’t act to clear the rubble and silt.
“The film will follow the Mytholmroyd Arts Festival film and I have asked if Anthony and Barry can take part in a Q&A chaired by Councillor James Fearon, Mayor of Hebden Royd, who features in the film and has expressed enthusiasm about taking part.”
Elland, Mytholmroyd, Hebden Bridge, Todmorden and Sowerby Bridge woke up on Boxing Day to flood waters of up to 6 feet, with homes and businesses devastated and communities cut off.
Calderdale Council estimated earlier this year that they will face a bill of at least £20m due to the damage caused by the flooding.
