| Abstract: | Measurements of geomorphological parameters were made every 10m along the entire length of Ball Creek / Coweeta Creek down to the Forest Service boundary. Measurements started 300m from the headwaters because most of the first 300m are underground. |

| Data Columns: |
Dist - Distance upstream from laboratory
boundary. Measured with a tape. It can be converted to distance from
headwaters by subtracting from 5550. Distance from headwaters is what is
marked along the stream. Elev - Elevation. Measurements were made every 50m (or less often downstream) and calibrated to known elevations from the Coweeta topographic map (weirs, roads). Measurements were made with the Forest Service altimeter. Elevations between measurements were calculated by interpolation. Gradient - Calculated from elevation 20m above and 20m below each site. Width - Bankfull width. Measured with a tape. Reach_U - Percent of 10m reach shaded by understory vegetation. Reach_O - Percent of 10m reach shaded by overstory vegetation. Rock - Percent of mineral substrate made up by rockface. Boulder - Percent of mineral substrate made up by boulder. Cobble - Percent of mineral substrate made up by cobble. GSS - Percent of mineral substrate made up by gravel, sand, and silt. Wood_Cov - Percent of mineral substrate covered by wood. Debris49 - Number of woody debris dams spanning less than 50% of the channel width. Debris51 - Number of woody debris dams spanning more than 50% of the channel width. Depth - Mean water depth. Average of 5 or more measurements made with a meter stick over the wetted width of the stream. Missing Data Codes: . (Period) |
