  • Flood risk and damage investigation in areas of high cultural heritage value : master thesis no.: 109/II.VOI-FRM
    Machado de Almeida, Livia Beatriz
    Floods affect more than a billion people every year, bringing direct damage through the destruction of buildings, infrastructure, and loss of life. On the other hand, it results in indirect social ... and economic damage through well-being and revenue reduction. Floods also impact irreplaceable cultural heritage, especially in coastal areas such as Piran, in Slovenia. Piran is known for its rich cultural heritage, having been occupied by several relevant civilizations, such as the Romans and the Byzantines. This municipality is constantly affected by floods and the tendency, according to climate change and sea level rise predictions, is for those floods to become more frequent and more destructive in the following years. The loss of cultural heritage is disastrous not only for tangible reasons, associated with the destruction of buildings or historical areas, their use, and the tourism it promotes but also because it erases part of the cultural identity and history of a community. To assess the financial impact of floods in Slovenia, Vidmar et al. 2019 created the KRPAN model, which uses depth-damage curves of residential buildings, businesses, and infrastructure to calculate annual damage. KRPAN provides the possibility to consider the damage on cultural heritage, however without accounting for its specific characteristics. The depth-damage curve used in the model is derived from FEMA (2014) and is not well-adapted to historical buildings. This work aims to improve the original KRPAN depth-damage curves for cultural heritage by making them more accurate with the aid of field data collected in Piran and a literature review of damage on cultural heritage and specific building materials found in the area. The literature research also comprises the impact of saltwater on cultural heritage buildings. Nevertheless, this impact was not considered directly in the damage calculation due to a lack of available data and resources to perform an in-depth chemical analysis of saltwater impacts on construction materials. A qualitative risk assessment was also performed in the area, according to the estimated vulnerability of the buildings, represented by a flood vulnerability index. Most of the assets are found to have a moderate or high flood vulnerability index (FVI). Besides that, intersecting FVIs values with flood hazard, the 51 buildings analyzed are classified in flood risk classes. Interpreting the results, it can be concluded that the influence of the sea level rise variation on the determination of flood risk classes (highest shift of 35% between classes) is bigger than the impact of the change of flood return periods (highest shift of 25% between classes). This means that cultural heritage in Piran is significantly vulnerable to floods, and, with the increasing sea level rise and the consequent deterioration of the buildings, the tendency is for these assets to become even more vulnerable. A superficial qualitative analysis of the long-term evolution of salt deterioration with the effect of climate change was also performed. This analysis led to the conclusion that the combination of the predicted increase in the number of cycles and increased flood event frequency would undoubtedly result in the augmentation of cultural heritage losses. In order to evaluate the calculated flood damage, the costs computed in the present work are compared with cultural heritage renovation data estimated and provided by the Ministry of Culture of the Republic of Slovenia and the results presented by Alivio (2020). The damage values increase as the sea level rise scenarios get more extreme. For a 10-year return period, values for a 1.46m sea level rise reach up to 529% of the costs for a 0.3m scenario and 25 times the costs for a no sea level rise scenario. Additionally, the impact of the sea level rise on the damage cost for cultural heritage buildings gets smaller as the return period gets longer. It should be noted that, in every scenario, the building located in Tartini Square 2 is the one that contributed the most to total damage, with damage costs up to 530 thousand euros for a 1000-year return period and a 1.46m sea level rise. The improvement of these curves would allow the designated authorities to better reduce and mitigate flood risk and the impact of climate change on cultural heritage, through the prioritization of sites to protect and a better understanding of the severity and financial consequences of these processes.
