This week has seen the 12th anniversary of the 2007 floods which impacted across swathes of the UK and affected villages, towns and cities across Yorkshire. It is timely to look at some of the measures put in place since then to alleviate flooding in the future. Natural flood management (NFM) has had some coverage in the media recently with both the BBC and ITV reporting stories that cover activities iCASP projects are supporting.
Countryfile recently visited Hardcastle Crags near to Hebden Bridge to find out more about leaky dams and how they will help tackle flooding in the future. The NFM work in Hardcastle is as a direct result of the 2015 Boxing Day floods. iCASP has been working with the Environment Agency, JBA and the Yorkshire Dales Rivers Trust, amongst others, on monitoring and measuring the range of benefits of NFM measures such as the leaky dams seen in the programme. The main focus of iCASP’s work has been developing approaches to measure whether or not the dams work to deliver flood alleviation. A future focus of the work will be to help quantify the additional benefits of these types of interventions – such as more varied habitat for wildlife, improved water quality and enhanced well-being for visitors to the area – which will be vital for making the business case for future natural flood management measures.

Natural flood management encompasses a range of different measures, not just leaky dams. An ITV news report on tree planting in Hebden Bridge mentioned how this work will draw upon the expertise of iCASP later in the year to understand the impact of trees already planted. iCASP will be working on the project to help identify how features, such as trees and hedges, can absorb heavy rainfall and contribute to alleviating flooding, as well as investigating how different soil types and land covers also contribute to flooding. Decisions on where trees and hedges should be planted in the future, for optimal benefit, will be informed by a rainfall-runoff model developed at the University of Leeds. Read the ITV report
These NFM activities rely upon a range of different partners getting involved. A diagram showing the range of different partner organisations, drawing from the voluntary, charitable, private, public and regulatory sectors, has been developed to give a flavour of the interactions in these activities in the Calderdale area.
