The algorithmic process described above was applied in the Mediterranean EU-27 countries to identify heritage assets under probable threat due to Sea Level Rise under RCP 2.6, 4.5, and 8.5 in 2050 and 2100. The area of interest was defined as an internal 2 km buffer zone from the hybrid coastline that was drafted. This zone contains very heterogeneous landscapes, including major ports (e.g., Barcelona, Marseille), mountainous regions, farmland, estuaries, environmentally protected sites, etc. Table 2 presents the calculated area, in square kilometers, expected to be affected by SLR per country. As can be seen in Figure 9, the coastal areas of Greece, France, and Italy are expected to be more affected by Sea Level Rise scenarios. At the same time, Malta, Slovenia, and Croatia do not seem to face significant threats and the effect of the different RCP scenarios remains rather constant per target year. That can be attributed to the extensive coastline of Greece and Italy but also to the geomorphology and elevation of certain parts of France, since France ranks 5 th in terms of coastline length but surpasses Spain and Croatia in the extent of the SLR-affected area (Table 2). Finally, it can be noted in Figure 9c that the effect of SLR is expected to be more prominent in Greece and Italy between 2050 and 2100 under the different RCP scenarios, while France, Cyprus, Croatia, Slovenia, and Malta will present a rather constant number of additional coastal flooded land under the three scenarios. Figure 8: Identification of new coastal areas expected to flood due to Sea Level Rise in 2050 and 2100 under RCP scenarios 2.6, 4.5, 8.5. Four UNESCO World Heritage Sites face significant danger from Sea Level Rise: the island of Delos, the Medieval City of Rhodes, Pythagoreion and Heraion of Samos in Greece, and the Amalfi Coast in Italy. Delos appears to be more sensitive as it is expected to be partially flooded under all three RCP scenarios for 2050 and 2100. In contrast, the other three sites are expected to present additional flooded areas only in 2100 and not 2050. With regard to the CH assets that were retrieved from OpenStreetMap, a total of 246 locations (out of a total of 3512 in the area of interest) are expected to be affected by SLR under one or more RCP scenarios in 2050 or 2100, more than 80% of which are located in the Greek and Italian coasts (Figure 10). \begin{table}

Table 2: Possible affected areas from SLR (in sq.km.) per country. Figure 9: (**a**) Graph presenting new affected areas by SLR (in sq.km) per country under different RCP scenarios for 2050, (**b**) Graph presenting new affected areas by SLR (in sq.km) per country under different RCP scenarios for 2100, (**c**) Graph presenting the additional new affected areas in sq.km by SLR between 2050 and 2100 under different RCP scenarios. The effect of different RCP scenarios does not appear significant at least for the 2050 projections. The number of CH assets under probable inundation risk, however, doubles and sometimes triples between 2050 and 2100, with Italy, France, and Spain also presenting high sensitivity under the different RCP scenarios (Figure 11). On the contrary, the coastal heritage assets of Croatia, Malta, Slovenia, and Cyprus seem to be more protected from SLR.
