Studies have shown that floods can cause an intangible impact, and the effects may increase with the increase in severity or intensity due to climate change. The intangible losses are rarely considered in flood damage assessment due to their subjectivity. This study aims to address the association between intangible losses with multiple factors, including socio-economic, flood, and building characteristics. The study used the contingent valuation method for the willingness to pay to assess public psychological impact in monetary terms. Face-to-face interviews were conducted in a different flooded area in Peninsular Malaysia to elicit costs for intangible losses in residential and commercial sectors. The results indicate that flood and socio-economic characteristics are statistically significantly correlated and contributed to the intangible damage in residential and commercial sectors. The findings justify the need for greater investment to reduce the effects of intangible losses, especially to the lower-income groups with limited adaptive capacity.
