I clipped a 10-meter resolution digital elevation model to the extents of a tract of Coronado National Forest in Southeastern Arizona. I then used hydrology tools in ArcGIS Pro to fill sinks, calculate flow direction, flow accumulation, and slope. Lastly, I calculated Topographic Wetness Index from the inverse function of adjusted flow accumulation divided by the tangent of slope.
