Elevation surface

Slope angle is a measure of gradient magnitude and influences e.g. flow velocit

Aspect angle represents gradient direction and e.g. direction of flow

Profile curvature indicates areas of accelerated flow (convex) and areas with decreasing flow velocity (concave)

Tangential curvature represents areas of convergent (concave) and divergent (convex) flow
