    [ta_slope_stability.0]\n
    This tool computes a slope stability (expressed as a factor-of-safety) raster according to the traditional infinite slope model theory (see cf Selby, 1993) The resulting raster represents the ratio of resisting forces/driving forces (fs) on a potential shear plane with fs lesser 1 unstable, fs greater 1 stable. Except for a slope raster (in radians), all input variables can be specified either globally or distributed (through grids). The tool creates a continuous fs raster (values above 10 are truncated), and a binary stability grid with nodata = stable, 1 = unstable (optional).\n

    This tool is a realization of the SHALSTAB (Shallow Slope Stability) model from Montgomery & Dietrich (1994). The model computes grid cell critical shallow groundwater recharge values (CR in mm/day) as a measure for relative shallow slope stability, utilizing a simple model that combines a steady-state hydrologic model (a topographic wetness index) to predict groundwater pressures with an infinite slope stability model. For computation, a slope (in radians) and a catchment area (in m2) grid are required. Additionally, information on material density (g/cm3), material friction angle (&deg;), material hydraulic conductivity (m/hr), bulk cohesion (MPa) and depth to potential shear plane (m) are required that can be specified either globally or through grids. The tool produces a continuous CR (mm/day) raster with unconditionally stable cells blanked, and unconditionally unstable cells as CR = 0. Optionally, a classified CR grid can be calculated representing seven stability classes.\n

    [ta_slope_stability.3]\n
    This tool calculates a topographic wetness index (TWI) following Montgomery & Dietrich (1994) that can be used to estimate the degree of saturation of unconsolidated, permeable materials above (more or less) impermeable bedrock. In contrast to the common TOPMODEL (Beven & Kirkby, 1979) - based TWI, this index differs in such that it considers hydraulic conductivity to be constant in a soil mantle overlying relatively impermeable bedrock. Also, it uses the sine of the slope rather than its tangens, which is more correct and significantly matters for steeper slopes that give raise to landslides. For computation, a slope (in radians) and a catchment area (in m2) grid are required. Additionally, information on groundwater recharge (m/hr), material hydraulic conductivity (m/hr), and depth to potential shear plane (m) are required that can be specified either globally or through grids. The tool produces a continuous wetness index (-) where cells with WI values > 1 (overland flow) set to 1, and optionally creates a classified WI grid rendering three saturation classes:.\n
    0): Low moisture (WI smaller 0.1)\n
    1): Partially wet (0.1 smaller WI smaller 1)\n
    2): Saturation zone (WI larger 1)\n

    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 (G&uuml;nther 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.

    [ta_slope_stability.5]\n
    This tool computes the acute angle raster between the topographic surface defined by slope and aspect rasters internally derived from input elevation raster, and a structural plane defined by diop direction- and dip grids. Optionally, the dip direction and dip of the cutting line linears between the two planes can be calculated\n

    Arguments
    ----------
    - DEM [`input grid`] : Elevation. A Digital Elvation Model (DEM)
    - C [`optional input grid`] : Dip grid (degrees) . A grid representing the dip of the structure plane (in degrees)
    - D [`optional input grid`] : Dip direction grid (degrees) . A grid representing the dip direction of the structure plane (in degrees)
    - E [`output grid`] : Angle. Acute angle (degrees) grid
    - F [`output grid`] : CL dipdir. Dip direction cutting line (degrees)
    - G [`output grid`] : CL dip. Dip cutting line (degrees)
    - fB [`floating point number`] : Global structure dip (degrees). Default: 45.000000 Constant value if no raster set
    - fC [`floating point number`] : Global structure dip direction (degrees). Default: 90.000000 Constant value if no raster set

    - Verbose [`integer number`] : Verbosity level, 0=silent, 1=tool name and success notification, 2=complete tool output.\n
    Returns
    ----------
    `boolean` : `True` on success, `False` on failure.
