Tangential Curvature
The Grids | Calculate | Calculus terrain model,Tangential Curvature, measures curvature in relation to a vertical plane perpendicular to the gradient direction, or tangential to the contour. The negative and positive areas are the same as for Plan Curvature, but the curvature values are different. Tangential Curvature is related to the Plan Curvature KHby the sine of the slope:

Tangential Curvature measures the curvature of the surface in the vertical plane perpendicular to the gradient direction. Negative curvature, displayed with gray fill, indicates divergent flow conditions. |
Tangential Curvature KTis given by the equation:
