Despite a proliferation of resilience measurement frameworks, empirical evidence for them is scant. This article presents a framework and tool for measuring community flood resilience, being tested in 75 communities in 10 country programs. 88 potential "sources of resilience" are collected. If a flood occurs, outcome measures are recorded. By comparing pre-flood characteristics to post-flood outcomes, we aim to empirically verify sources of resilience, something which has never been done.
