Flooding causes serious impacts on the old town of Venice, its residents, and its cultural heritage. Despite this existence-defining condition, limited scientific knowledge on flood risk of the old town of Venice is available to support decisions to mitigate existing and future flood impacts. Therefore, this study proposes a risk assessment framework to provide a methodical and flexible instrument for decision-making for flood risk management in Venice. We first use a state-of-the-art hydrodynamic urban model to identify the hazard characteristics inside the city of Venice. Exposure, vulnerability, and corresponding damage are then modeled by a multi-parametric, micro-scale damage model which is adapted to the specific context of Venice with its dense urban structure and high risk awareness. Furthermore, a set of individual protection scenarios are implemented to account for possible variability in flood preparedness of the residents. This developed risk assessment framework was tested for the flood event of 12 November 2019 and proved able to reproduce flood characteristics and resulting damage well. A scenario analysis based on a meteorological event like 12 November 2019 was conducted to derive flood damage estimates for the year 2060 for a set of sea level rise scenarios in combination with a (partially) functioning storm surge barrier, the Modulo Sperimentale Elettromeccanico (MOSE). The analysis suggests that a functioning MOSE barrier could prevent flood damage for the considered storm event and sea level scenarios almost entirely. A partially closed MOSE barrier (open Lido inlet) could reduce the damage by up to 34 % for optimistic sea level rise prognoses. However, damage could be 10 % to 600 % higher in 2060 compared to 2019 for a partial closure of the storm surge barrier, depending on different levels of individual protection.

Climate change impacts on diverse cultural heritage is gaining scholarly and policy attention, yet little research has been conducted on how can diverse cultural heritage inform decisionmakers and policymakers in achieving climate change actions (i.e., climate change adaptation and mitigation). For this study, we conducted semi-structured interviews with Dutch cultural heritage and environmental or climate change experts (n = 52) and participant observations across the Netherlands to explore the importance of cultural heritage benefits and their relation to climate change actions. We also explored the perceptions of cultural heritage management over time, including the influence of climate policy on heritage practice in the Netherlands. Our findings show that experts perceived a multiplicity of heritage benefits as important in supporting and informing present and future climate change actions. The most salient benefits were informational benefits where diverse cultural heritage is perceived as an important source of knowledge about past societal, economic and environmental developments and changes. Further, heritage management was perceived as constantly changing over time, reflecting the transformative nature of diverse heritage types. Experts agreed that climate policy has already influenced cultural heritage practice in the Netherlands. Lastly, the interrelationships between heritage benefits and management were identified and characterised. This study informs both cultural heritage and climate change research agendas and helps leverage diverse cultural heritage into climate change adaptation and mitigation policies., (Copyright © 2020 The Authors.
