schematic - The relationship between watershed delineation and surface hydrology.

maps and charts - The spatial location, surface elevation and slope distribution of the CBF watershed. Upper left is the location on Google Map; Upper right is the histogram of surface slope (degree); and bottom is the spatial distribution of surface elevation (m).
