The Output Tab allows the user to preview the channels and ridgelines that will be contoured to reveal the draft GeoFluv™ design landform, to draw and contour the surface, to save the design, to verify the average drainage density within the GeoFluv Boundary, to compare the cut and fill volumes needed to create the design and to verify that the cut and fill volumes balance within a user-specified limit, and to create and view a summary report of the channel settings and design dimensions.
