Table 6: Overview of the selected WDR spells for each of the five selected periods of time. higher water content value (43.5 kg/m\({}^{3}\)) because the assembly is not able to dry out the moisture that managed to penetrate from previous spells. Figure 14: Water content (kg/m\({}^{3}\)) across the wall assembly and in accordance with time for spell 1 (**a**), spell 2 (**b**), and spell 3 (**c**) for the near past (NP) for Lisbon and precipitation (L/(m\({}^{2}\)h)) during spell 1 (**d**), spell 2 (**e**), and spell 3 (**f**). The blue lines in (**a**–**c**) correspond to water content across the assembly for any given period within the corresponding spell limits. Figure 14c corresponds to the third selected spell, which has a duration of 235 h and a total precipitation during the spell of 18.4 L/(m\({}^{2}\)h). In this spell, the extra period was not considered because, contrary to the other two spells, there is no significant WDR event near the end of the spell (Figure 14f). This spell has a longer period than the first spell (20% higher) but much lower total precipitation (47% lower). The water content reaches its highest value of 15.8 kg/m\({}^{2}\) on 02/04 at 18:00 and its lowest value of 9.1 kg/m\({}^{2}\) on 01/04 at 14:00. This shows that although this is a wider spell with lower precipitation than the second spell, it reaches similar values (Table 7), which means that the state in which the assembly is due to previous spells is also of great importance. It is visible that at the beginning of the spell (i.e., 28/03 at 18:00), there is a great amount of moisture already trapped in the solid brick. Due to the absorbed precipitation within the spell, the values will increase throughout the assembly. Even when the spell finishes (Figure 14c, purple line), the values are still rather high, but they will decrease as the assembly dries, which is already visible at the outer layers of the exterior surface when the spell finishes. In this case, the absorbed moisture is able to reach a depth of 200 mm (at 8.9 kg/m\({}^{3}\)). By comparing this with the other spells, it is visible that the excess of moisture is increasing, since the assembly is not able to dry out all the absorbed moisture.
