Geophysical and social vulnerability to floods at municipal scale under climate change: The case of an inner-city suburb of Sydney

Assessments of vulnerability to flooding can generate useful data for planners and policy makers. To the best of the authors knowledge, no flood-vulnerability study has combined geophysical modelling of floods with socio-economic assessments of vulnerability at finer municipal or household scale. In...
