<p>F1, F2 and F3 are calculated according two functions of Romana (1995) and of Tomàs et al. (2007). The functions proposed by Romana are discrete, instead Tomàs et al. (2007) proposed continuous functions that reduced subjective interpretations.
<p><b>SSPC approach (optional)</b>: inserting TC value (or a map of TC values) it's possible to obtain a SSPC map according to Hack's classification (Hack, 1998). Only a part of the method introduced by Hack is used in the module: the orientation dependent stability (the stability depend on relation between slope and discontinuity orientation). According to the author:
<ul>
- <li>sliding occurs if: TC < 0,0113*AP</li>
- <li>toppling occurs if: TC < 0,0087*(-90-AP+dip)</li>
+ <li>sliding occurs if: TC < 0,0113*AP</li>
+ <li>toppling occurs if: TC < 0,0087*(-90-AP+dip)</li>
</ul>
<p>where AP is the apparent dip, TC is the condition factor for a discontinuity. TC can be calculated by multiplying the large scale roughness, the small scale roughness, the infill material and the karst factors observed in the field:
