Penning-Rowsell, E.C., Priest, S.J., Parker, D.J., Morris, J., Tunstall, S.M., Viavatenne, C., Chatterton, J., and Owen D. (2013)  Flood and Coastal Erosion Risk Management. A manual for economic appraisal, Routledge, London (ISBN 978-0-415-81514-4 (hbk) 978-0-203-06639-3 (ebk))

This manual draws on collaboration between the Flood Hazard Research Centre at Middlesex University, Defra, the Environment Agency and others stakeholders and is known as the ‘Multi-Coloured Manual (MCM)’.  It is an update of the 2005 manual of this name but includes a range of brand new methods and data. The manual is accompanied by MCM-Online which provides everything available in the manual plus a vast array of benefit data together with methods, techniques and guidance for its application.


The Multi-Coloured Manual (MCM) Handbook is intended to be a stand-alone “Step-by-Step” guide to assessing the benefits of flood and coastal erosion risk management.  When put together with the knowledge of the costs of the plans and schemes required, the user can assess the relationship between the benefits and costs of investment decisions.  This comparison should enable the users to identify those risk management plans and schemes which maximise the economic return and therefore, represent “best value for money” by being economically efficient.

MCM-Online is available to professional users under licence agreement although there is also a free to use public division of this website.   This updated version of the MCM provides a completely new set of potential; flood damage data for non-residential properties (including retail and office businesses, industry, logistics and public buildings).  By clicking on the membership page, you can find details of the licences (including Education, Standard and Corporate) which provide access to the Handbook and associated damage and loss data.
