### Moisture Penetration
#### 3.3.4 Future Climates--Scenario RCP 8.5
In this case, contrary to what was seen previously, the beginning of the spell corresponds also to the period with the lowest water content. It is visible that when the spell starts, the water content near the exterior is already considerably high, whereas for the remainder of the assembly, it is rather low (i.e., 08/03 at 03:00). These high water content values near the exterior surface are due to the occurrence of several WDR events near the start of the spell (Figure 18c). It is visible that once the spell starts, the moisture from the exterior is able to enter the assembly, and, consequently, the water content value increases throughout the cross-section (Figure 18a). At the end of the spell (Figure 18a, purple line), the drying of the wall is already visible. Here, the outdoor moisture manages to reach a depth of 114 mm at 14.5 kg/m\({}^{3}\). Figure 18b shows the water content for the second selected spell, which lasts for 133 h and has a total precipitation of 16.2 L/(m\({}^{2}\)h). This spell is shorter than the first spell (63% shorter), and it has lower precipitation (48% lower) but reaches similar water content values to the first spell (Table 7). The highest water content value of 12.6 kg/m\({}^{2}\) is attained on 09/03 at 00:00, while the lowest water content value of 7.4 kg/m\({}^{2}\) is attained on 08/03 at 03:00. For this case, the beginning of the spell corresponds to the period with the lowest water content. It is visible, right from the beginning of the spell, high water content values near the exterior surface, since a concentration of WDR events near the beginning of the spell are visible (Figure 18d), but there are also rather high values for the remainder of the assembly (Figure 18b, red line), at least compared with the previous spell (Figure 18a, red line). This can be caused by the non-complete drying of the previously absorbed moisture. Once the spell starts, the amount of moisture within the assembly also starts to increase considerably (Figure 18b). Finally, a clear distinction between the end of the spell and the extra 24 h is visible, at least near the exterior surface, which is natural, since the assembly has started to dry from the outer surface whilst some of the moisture goes inside. For this case, the outdoor moisture is able to reach a depth of 94 mm at 36.5 kg/m\({}^{3}\). Figure 18c shows the water content for the third selected spell, which lasts for 127 h and has a total precipitation of 23.0 L/(m\({}^{2}\)h). This spell is shorter than the first spell (65% shorter) and the same approximate size as the second spell (only a difference of 6 h). This spell has lower precipitation than the first spell (26% lower) but higher precipitation than the second spell (42% higher). The highest water content value of 10.0 kg/m\({}^{2}\) is attained on 22/10 at 18:00, while the lowest water content value of 1.7 kg/m\({}^{2}\) is attained on 17/10 at 13:00. It is interesting to notice that the highest water content value is attained when the spell ends, due, probably, to the concentration of WDR events near the end of the spell (Figure 18e). Some of the previous described behaviours also occur here, i.e., at the beginning of the spell, the water content values are relatively high near the surface but rather low throughout the remainder of the assembly (Figure 18c, red line). Once the spell starts, the water content increases at the exterior surface and then spreads out to the remainder of the assembly (Figure 18c). The drying of the assembly is already visible at the end of the spell but much more significant 24 h later (Figure 18, purple and green lines). For this case, the outdoor moisture is able to reach a depth of 125 mm at 6.1 kg/m\({}^{3}\).
