#### 3.3.3 Future Climates--Scenario RCP 4.5  
Figure 15a,b present the water content profile for the tested assembly for the selected two spells for the near future for scenario 4.5 (Table 6), while Figure 15c,d show the respective precipitation for each spell. Both spells show the results for an extra 24 h after the spells have ended because they had a substantial precipitation event right before the spell ended (Figure 15c,d). Figure 15a corresponds to the first selected spell, which has a duration of 203 h and a total precipitation during the spell of 33.8 L/(m\({}^{2}\)h). The water content reaches its highest value of 15.6 kg/m\({}^{2}\) on 22/01 at 20:00 and its lowest of 3.3 kg/m\({}^{2}\) on 14/01 at 23:00. The behaviour here is similar to that of the first spell in the near past (Figure 14a). The water content in the assembly starts at low values (i.e., 14/01 at 10:00), but it is visible that as time progresses, the amount of moisture within the assembly increases. The values at the exterior surface reach saturation (Figure 3) during the most significant WDR events, which eventually spread out to the remainder of the assembly (Figure 15a). By comparing the water content between the end of the spell and the extra 24 h, it is visible that the assembly manages to dry, more obviously nearer to the exterior surface for the mortar layer and closer to the interface for the solid brick (Figure 15a). Although at the interface, they may have similar RH values, they will have a considerable difference in terms of moisture content since they are different materials, and, consequently, have different moisture storage functions (Figure 3). The exterior moisture manages to penetrate up to a depth of 114 mm with 18.0 kg/m\({}^{3}\). Figure 15b corresponds to the second selected spell, which has a duration of 25 h and a total precipitation during the spell of 25.1 L/(m\({}^{2}\)h). Although it is a much shorter spell than the first one (88% shorter), its total precipitation is not very distant (26% shorter). The water content reaches its highest value of 14.9 kg/m\({}^{2}\) on 20/12 at 09:00 and its lowest value of 5.5 kg/m\({}^{2}\) on 19/12 at 23:00. The behaviour here is similar to that of the second spell in the near past (Figure 14b), although this one occurs in December while the other occurs in March. The water content in the assembly starts at low values on the inner surface and at higher values nearest to the exterior surface (Figure 15b, red line). Nonetheless, it is visible that as time progresses, the amount of moisture within the assembly increases. The values at the exterior surface also reach saturation (Figure 3) during the most significant WDR events, which eventually spread out to the remainder of the assembly (Figure 15b). By comparing the water content between the end of the spell and the extra 24 h, it is visible that the assembly manages to dry, even more than at the beginning of the spell. This behaviour is more evident the nearerto the exterior surface we analyse (Figure 15a). The exterior moisture manages to penetrate up to 107 mm depth at 12.1 kg/m\({}^{3}\), slightly lower than the first spell (Table 7). In conclusion, although the second spell is a much shorter spell than the first, the amount of moisture that manages to penetrate the assembly is similar, thus reaching almost the same depth. This means that shorter spells can be as dangerous as wider ones. Figure 16a-c present the water content profile for the selected three spells for the far future for RCP 4.5 (Table 6), while Figure 16d-f show the respective precipitation for each spell. The three spells show the results for an extra 24 h after the spells end because they had a substantial precipitation event right before the spell ended (Figure 16d-f). Figure 16a shows the water content for the first selected spell, which lasts for 73 h and has a total precipitation of 16.3 L/(m\({}^{2}\)h).
