    Global climate change is anticipated to result in changed precipitation characteristics and an increase in the frequency of extreme weather events, which can lead to catastrophic flood damage. ... Results of the climate change studies in Slovenia foresee a considerable rise in the average air temperature, changes in the frequency of precipitation characteristics, and an increase in the occurrence of extreme weather events. According to climate change scenarios RCP 2.6, RCP 4.5, and RCP 8.5, the average annual peaks of Slovenian rivers will rise by 20 to 40% by the end of the century at almost all water stations (ARSO, 2021). The Vipava river catchment is an area located in western Slovenia; the area is vulnerable to river flooding and has been subjected to several flood events in recent years which could be associated to changes in the precipitation as one of climate change's effects Detailed flood damage analysis has not been conducted for the Vipava river catchment, and accurate estimation of flood damage is crucial to quantifying the actual flood risk and evaluating the cost-effectiveness of flood mitigation measures. Flood damage assessment for the Vipava river catchment was conducted in this study by considering different flood scenarios. The flood damage potential was investigated based on the designed flood event data adapted to specific flood scenarios related to anticipated impact of climate change and the presence of exposure/vulnerability elements. Hydraulic modeling using Hec Ras software is used to identify the flood polygons in the study area for current and climate-driven flood scenarios. The output of the hydraulic model is used as an input to KRPAN software to determine the flood damage potential in the study area. According to the results of the hydraulic model, extensive floodplain areas along the studied Vipava river section are inundated, primarily covering agricultural land and buildings. The cost of both residential and non-residential buildings constitutes the majority of the projected flood damage for the specified flood return periods. The building's overall expected annual damage under the pessimistic RCP 8.5 scenarios is expected to reach around 1.3 million by the end of the century, In case of low probability events with 100- and 500-year return periods, the cost of the building's flood damage ranges from 4.5 million euros to 6 million euros. The total expected annual damage in the Vipava river catchment ranges from 0.97 million euros for the current situation to 1.97 million euros for the most pessimistic high-impact scenario. The study clearly shows that the economic impact of future flood scenarios is expected to increase substantially In view of the local character of the exposure elements, the residential properties and non-residential properties were demonstrated to face the greatest consequences of expected climate change-induced changes in the river flood characteristics.
