| Abstract: | Understanding and improving the public perception has become an important element in the management of flood risk worldwide.
In Iceland, studying perception of flood hazard and flood risk is, however, in its early stages. This paper presents a case
study on the public perception of flood hazard and flood risk in an Icelandic town prone to ice-jam floods. Awareness of the
population regarding historical inundations, self estimation of flood risk and worry is considered. The factual knowledge
of the residents is deconstructed in flood hazard parameters accessible to the lay population: number of events, dates, genesis
and boundaries. The performance of the respondents is rated for each parameter and the influence of several predictors evaluated.
The research shows three significant patterns: there is poor awareness and little worry about historical inundations in the
area; experience of the past flooding events in town is the most effective source of knowledge; awareness, risk estimation
and worry are not correlated. |
