Flexibility is often proposed as a valuable capability to cope with uncertainty and change. However, there is no consensus about what constitutes flexibility across the literature. A review of publications on flood management, real options and manufacturing reveals remarkable commonalities along with substantial inconsistencies in the use of flexibility. These observations are used for structuring the discussion of flexibility in this paper. A framework is proposed in the form of four self-consistent and step-wise questions: (Q1) why is flexibility needed; (Q2) what is it that flexibility is required for; (Q3) what are the dimensions of flexibility; (Q4) what needs to change or be adapted? In order to answer the questions in the context of multifunctional flood defences (MFFDs), eight characteristic features of flexibility in connection with the four questions are distilled from the synthesized publications. Subsequently, a working definition of flexibility is developed. An illustrative case study examines the framework's potential for the development of a MFFD. It is shown that the iterative use of the framework can serve as a guideline for identifying and evaluating flexibility for MFFDs. The paper ends with some challenges for future research.

WaStop Inline Check Valve protects Hull from Flooding - Case Study
Location: Hull, United Kingdom Client: The Environmental Agency, Hull City Council & Associated British Ports Problem: In December 2013 a storm surge caused water to over top the existing flood defence along the Humber frontage and on the Albert dock causing flooding and widespread damage. Once the water had over topped the flood defences it filled the dock and was then able to run downhill and enter the surrounding industrial and residential areas. One of the biggest victims of the flooding was Smith &...
Mangroves for coastal defence
The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves in coastal defence and put the different findings and views in perspective. The conclusion is that mangroves can...
Innovative Glass Flood Defence for Keswick, Cumbria
In September 2011, IBS Engineered Products Ltd was awarded a contract by main contractor VolkerStevin to design, supply and install a glass wall flood defence system for Keswick, Cumbria.

Flood and Coastal Risk Management - Case Study England
The Environment Agency is the principal flood risk management operating authority. It has the power (but not the legal obligation) to manage flood risk from designated main rivers and the sea. These functions in relation to other rivers (defined as ordinary watercourses) in England and Wales are undertaken by Local Authorities or Internal Drainage Boards. The Environment Agency is also responsible for increasing public awareness of flood risk, flood forecasting and warning and has a general supervisory duty for...
