Available tools
- Alluvial Fan Radial Slope Term Tool Calculate alluvial fan radial slope term from explicit caller-supplied inputs.
- Bank Retreat Pin Angle Projection Tool Project an explicit signed erosion-pin displacement onto a supplied retreat axis using a radian angle without inferring bank processes.
- Bank Retreat Reference Axis Sign Tool Calculate bank retreat reference axis sign from explicit caller-supplied inputs.
- Beach Cross Section Panel Area Integrate one linear beach-profile panel relative to an explicit vertical zero using signed trapezoidal area.
- Beach Profile Trapezoid Area Term Tool Signed cross-sectional trapezoid area above an explicit elevation reference.
- Catchment Outlet Elevation Drop Term Tool Calculate supplied upstream-minus-outlet elevation on a shared vertical datum without estimating relief from a terrain model.
- Channel Chi Coordinate One Reach Term Tool Constant-area reach quadrature for chi=integral(A0/A)^theta dx, increasing upstream.
- Channel Reach Bedload Mass Term Tool Integrate a supplied uniform bedload mass flux per unit width and time over explicit active width and duration.
- Channel Sinuosity Distance Factor Tool Calculate channel sinuosity distance factor from explicit caller-supplied inputs.
- Channel Sinuosity Valley Reference Ratio Tool Distinguish channel/valley sinuosity from channel/direct endpoint ratio in a consistent planar projection.
- Dem Height Difference Threshold Compare a supplied DEM elevation change with an explicit strict magnitude threshold without estimating survey uncertainty.
- Drainage Density Map Length Area Factor Tool Drainage density in matched physical length/area units; areaScale is an area conversion factor, not a linear map scale.
- Dune Migration Signed Baseline Offset Tool Calculate supplied later-minus-baseline dune position along one explicit signed survey axis without deriving transport rates.
- Dune Slipface Angle Projection Tool Planar slipface projection in radians; signed angle preserves face orientation.
- Erosion Pin Reference Exposure Delta Tool Positive exposure increase is erosion; positive upward pin movement is subtracted from the apparent change.
- Geomorphic Surface Age Bound Token Tool Preserve an explicit geomorphic surface age transcription and bound convention without dating or calibration.
- Grain Class Boundary Closure Token Tool Resolve one caller-supplied grain-size boundary without selecting a classification scale.
- Grain Size Phi Step Tool Compute the phi-scale change −log2(d2/d1) for compatible positive grain diameters.
- Grain Size Phi Uncertainty Width Transform Tool Exact asymmetric uncertainty transform under phi=-log2(diameter in mm), with reversed interval order.
- Grain Size Support Share Tool Count only wholly supported supplied grain-size bins, without prorating unknown within-bin distributions.
- Hillslope Profile Curvature Three Point Term Tool Calculate an equal-spacing three-point elevation second derivative, distinct from slope-normalized geometric curvature.
- Landslide Scar Head Toe Distance Term Tool Calculate supplied head-to-toe plan and three-dimensional straight-line distances without reconstructing a landslide travel path.
- Landsurface Roughness One Cell Residual Tool One weighted squared detrended elevation contribution; a plane fit is supplied rather than estimated.
- Profile Curvature Sign Term Tool Classify an explicitly supplied profile second derivative under a declared vertical orientation, not a fitted terrain curvature.
- Profile Reference Step Gap Tool Calculate profile reference step gap from explicit caller-supplied inputs.
- Relief Ratio Basin Length Term Tool Schumm basin relief ratio using basin length and relief in the same length unit.
- River Knickpoint Gradient Residual Subtract an explicit reference channel gradient without detecting or interpreting a knickpoint.

- Sediment Bin Width Factor Tool Normalize supplied sediment-bin mass by explicit linear-size or natural-log-size width.
- Sediment Budget Storage One Compartment Tool Constant sediment mass-rate balance; a negative final storage exposes an inconsistent supplied scenario.
- Sediment Bulk Density Basis Flag Tool Calculate sediment bulk density basis flag from explicit caller-supplied inputs.
- Sediment Clast Axis Shape Ratio Tool Axis ratios and maximum-projection sphericity proxy [c^2/(ab)]^(1/3), with a>=b>=c.
- Sediment Grain Phi Diameter Crosswalk Convert between millimeter grain diameter and phi=-log2(diameter in millimeters) without assigning sediment classes.
- Sediment Particle Roundness Source Row Tool Preserve an explicit sediment particle roundness transcription and reference scale without image classification.
- Sediment Transport Porosity Volume Factor Tool Calculate sediment transport porosity volume factor from explicit caller-supplied inputs.
- Shoreline Retreat Transect Two Date Term Tool Endpoint shoreline change along one consistent transect, retreat positive under an explicit coordinate direction.
- Shoreline Signed Transect Offset Reference a supplied shoreline transect position using an explicit seaward-positive sign convention.
- Shoreline Tide Stage Reference Offset Tool Remove an explicitly supplied signed horizontal tide-stage offset from a shoreline coordinate without estimating beach slope or water level.
- Slope Break Angle Difference Tool Compare two supplied directed slope angles without a geomorphic process classification.
- Stream Power Unit Width Term Tool SI stream power rho*g*Q*S in W/m and width-normalized power in W/m2.
- Terrace Height Reference Gap Tool Calculate terrace height reference gap from explicit caller-supplied inputs.
- Terrace Riser Height Datum Gap Tool Offsets are added to place both elevations on a common vertical datum; negative riser values remain visible.
- Terrain Rise Run Gradient Express supplied signed terrain rise over positive horizontal run as a ratio and percent grade.
- Valley Floor Confinement Width Ratio Tool Divide supplied valley-floor width by positive channel width without assigning a confinement class.
- Valley Width Depth Relative Index Tool Valley floor width-to-height ratio Vf=2Vfw/[(Eld-Esc)+(Erd-Esc)] under the supplied divide elevations.
- Valley Width Reference Height Gap Tool Local linear width-height adjustment using a supplied gradient, not reconstructed terrain geometry.
