Résumé :
|
The use of the Handbook and its data CD is recommended for benefit assessment as part of flood and coastal erosion risk management appraisal. The latest 2010 version of the Handbook provides users with: - Easy access to the techniques and information needed to undertake evaluations of the benefits for most straightforward risk management projects (probably 75% to 85% of all cases); - A greater opportunity to align the scale of the appraisal effort with the scale and scope of the decisions required - Techniques that fully support sustainable development principles Importantly, the handbook provides approaches to implement the policies set out in the HM Treasury ‘Green Book’ and complements the Flood and Coastal Erosion Management Appraisal Guidance (FCERM-AG), published by the Environment Agency in March 2010. The Handbook also complements Defra’s making Space for Water principles and the Environment Agency’s increasing use of Multi-Criteria Analysis, as set out in its FCERM-AG advice. The 2010 version represents the results of research and development effort to update the data and techniques in the previous 2005 version, but remains a companion volume to the Multi-Coloured Manual, which will be the subject of a more fundamental update this year.
