Data to accompany the manuscript: Interactions between public and private flood adapation: insights from a socio-hydrological model

This data set consists of 3770 household responses from flood prone municipalities in Austria, taken during four different survey campaigns between 2014 and 2020. Details of the surveys are provided in Seebauer and Babcicky (2020; 2021); Babcicky and Seebauer (2019; 2020) and Babcicky et al. (2021). The surveys conformed with ethics guidelines of the involved research institutions and the pooled data set was anonymised. For this study, the survey responses relating to multiple questions on each of the themes of perceived threat of flooding, degree of damage experienced, degree of reliance on public flood protection measures, perceived effort to implement household measures, as well as intent to implement measures were pooled together to item indices. Z-scores were calculated to normalise the indices within each survey campaign, thus allowing to pool data from different survey regions and survey years. Surveyed households also stated whether a flood had been experienced, when a flood was last experienced, how many times a flood has been experienced, whether the householder believed they lived in a flood risk zone, as well as the presence and number of household preparedness and structural measures implemented. Household preparedness relates to measures such as an insurance policy that covers flood damage and an emergency preparedness plan, while household structural measures include installing flood barriers at doors and windows and placing electrical wiring above the water line.
