How 'leaky dams' are helping to reduce floods

Traditional dry stone walling skills are being used to install thousands of "leaky dams" in northern England in efforts to reduce flooding and create new habitats. Landscapes for Water, a joint project between National Trust and Yorkshire Water, has built more than 2,000 dams out of a planned 3,500 in the South Pennines. The wallers have been working in the uplands of Marsden Moor, West Yorkshire, to help hold back water, restore the blanket bog and reduce flooding downstream in Huddersfield and surrounding areas, Nicola Rees reports.
