  1. Diffuser Performance Assessment Kanawha River, WV Blaine Linkous UT – Austin The Advent Group, Inc.

  2. Map Components Data Sources: • Stream Network from NHD • DEM grid from NED • Digital Orthophoto from West Virginia DEP • Digitized USGS quad map from WVDEP • Field Measurements

  3. Constructing a Basemap from Components

  4. Constructing a Basemap from Components

  5. Coordinate System / Datum • UTM coordinate system • Zone 17N = Belle, WV • NAD83 • Orthophoto was originally UTM/NAD27 • NHD, NED were originally geographic • Field Measurements are relative to the diffuser; not the UTM x/y coordinate system.

  6. Field Study Info • Rhodamine WT dye • Located on river relative to the diffuser and the right edge of water by a surveying crew (on land) • Samples taken from: • surface • 0.2 (total depth) • 0.6 (total depth) • 0.8 (total depth) • bottom

  7. Coordinate System Rotation R = (DScos318o + REWcos228o)i +(DSsin318o + REWsin228o)j

  8. Addition of Min. Dispersion Values

  9. Another View of Min. Dispersion

  10. ArcScene used to create TIN from DEM Grid
