Service Description: Curvature is derived from the 10-meter DEM in the direction of slope gradient (profile curvature) and perpendicular to the gradient (plan curvature). Calculated at 10m, 20, 30, and 50m resolution. Profile curvature affects the acceleration and deceleration of flow, while the plan curvature affects the convergence and divergence of the flow. The final surface has values where higher values represent concave slopes, where moisture accumulates, and lower values represent more convex slopes, where runoff occurs.
Purpose: The purpose of this dataset is to weight the CETWI model based on terrain relationships between local hillslope process that accumulate or shed surface moisture based on convex or concave hillslope morphologies.
