Is there a correlation between intensity of agricultural nutrient use and water quality degradation in the Inland Bays?
The image on the left shows an analytically hill-shaded version of the DEM for the Inland Bays Watershed. The image was created by compositing hue from the source DEM and intensity from an aspect map generated from the DEM. The image on the right shows the initial drainage basin delineation from the r.watershed module, with black lines indicating groupings of sub-basins into the five principal basins. Portions of Sussex county outside these basins are masked out of both images.
