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
