CE 547 Geographic Information Systems in Water Resources Engineering
I imported the three DEM files. I used the mosaic and fill tools, then followed the directions for delineating watersheds. I used the hydrology tools and the raster calculator in Spatial Analyst to identify the stream, the Rio Puerco, and delineate the watershed and sub-watersheds. I played with the different color gradients for elevation for displaying the reference maps. The colors I used seem kind of extreme, but I like the way the high and low elevations are accentuated with that color scheme.
