The aim of this paper is to develop the simulation of rock moisture with WUFI in two investigation areas. From a geological perspective alone, both areas showed considerable differences in relation to the parameters for rock moisture modeling; while Johnsbachtal is composed mainly of limestone and dolomite Sonnblick is composed of gneiss. The differences between the two were seen when the most important climate parameters were examined: the rainfall, temp. and wind for both areas were in stark contrast mainly due to their heights above sea level. The paper further aims to describe the methodology in which the WUFI structure. Once these parameters were defined, simulations were carried out and charts which illustrate the annual cycle of moisture content. As WUFI offers a particularly wide range of settings options, simulations were carried out for each rock type with a north, south, east and west aspect, with an incline of 70 and 90. However, the north was damper than the south in almost all simulations and rock walls with a greater incline were always drier than those with a lesser incline. In order to assess the prevailing rock weathering and the resulting rock fall in each area, these results were supplemented with the classification of different weathering-relevant temperature parameters such as depth of frost penetration, length of frost, change in frost, etc. at different rock depths. The results were additionally discussed from different perspectives; besides differences caused by aspect, rock, incline and weather, the influence of climate change on rock moisture was analysed. The results predict that rock moisture levels on Sonnblick will increase, while mean rock moisture on Johnsbachtal will remain the same. Based on two frost-weathering theories, the combination of temperature and moisture levels implies that frost-weathering rock fall may occur but, again, aspects in both areas with higher levels of rock moisture are more likely to experience rock fall.
