Flood resilience is emerging as a major component of an integrated strategic approach to flood risk management. This approach recognizes that some flooding is inevitable and aligns with the concept of ‘living with water’. Flood resilience measurement has been recognized as key for
making the business case for investments in resilient retrofits and adaptations and, could potentially be used to inform the design of new developments where there is a risk of flooding. The literature is however sparse on frameworks for quantifying or measuring the level of
resilience of flood prone households. This study describes the development of a fuzzy logic based flood resilience measuring model, drawing on a synthesis of extant flood resilience and fuzzy logic literature. An abstraction of the flood resilience system followed by identification
and characterisation of systems’ variables and parameters were carried out. The resulting model was transformed into a fuzzy inference system (FIS) using three input factors; Inherent resilience (IR), Supportive Facilities (SF) and, Resident Capacity (RC). The resulting fuzzy inference
system generates resilience index for households with a wide range of techno-economic and socio-environmental features. It is concluded that the fuzzy logic based model provides a veritable tool for the measurement of flood resilience at the level of the individual property, and
with the potential to be further developed for larger scale applications i.e. at the community or regional levels.
