DEMs.

The 30 meter DEMs were delineated in a similar fashion to the 10 meter The DEMs used for this study are Pflueastm (Pflugerville East),

(Pflugerville West), Manorm (Manor), (Austin West), and Austinestm (Austin East).

In the same process as done for the 10 meter DEM, LULC and STATSGO data were prepared for the 30 meter DEM. The results for the three areas are shown below. In both cases (10 meter and 30 meter DEM delineations) an outlet was added to delineate the large watershed at the confluence with Buttermilk. Figure 4.10 shows the three areas delineated separately, and the longest flow path for each.
