SAGA.ta_slope_stability.4: WEDGEFAIL

<br/>This tool determines terrain elements where failure (slide- or topple movements) on geological discontinuies are kinematically possible through the spatial application of common frictional feasibility criteria (Günther et al. 2012 and references therein). Both the orientation of slope elements specified through aspect- and dip grids (in radians) are required together with the orientation of one planar structure defined through global- or grid dip direction and dip data, or two planar structures defined by plunge direction and plunge information of their intersection line (in degrees). The shear strength of the discontinuities is specified using global or grid-based friction angle data. Optionally, a cone value can be set allowing for some variance in discontinuity dip orientations. The tool operates in slide (testing for plane and wedge sliding) or topple (testing for plane and wedge toppling) modes.<br/><br/>Reference:<br/><a href="http://link.springer.com/article/10.1007/s11069-011-9771-2.">Günther A., Wienhöfer J., Konietzky H.
