Table B-1
shows an example of the discharge data file format. The
file has the following layout.
•
Row 1: Data file name
•
Row 2: Start date/time
•
Row 3: Track reference (ADP, Bottom-Track, GPS)
•
Row 4: Flow velocity reference (ADP, Bottom-Track, GPS)
•
Row 5: Unit System (English, Metric)
•
Row 6: Blank line
•
Row 7: Parameter names for columns
•
Row 8: Parameter scaling for columns
•
Row 9: Dashed line
•
Row 10+: Profile data; one row for each profile collected
•
Column 1: Profile – The profile number.
•
Column 2: Time – The starting time of the collected profile.
•
Column 3: Distance – The total distance traveled to the current profile (not straight-line).
•
Column 4: DMG – The distance made good (i.e., straight-line distance) from the data set’s
starting point (0,0 coordinates) to this profile.
•
Column 5: DistEast – The distance East (+) or West (–) from the data set’s starting point
(0,0 coordinates) at which this profile was collected.
•
Column 6: DistNorth – The distance North (+) or South (–) from the data set’s starting
point (0,0 coordinates) at which this profile was collected.
•
Column 7: GPS Latitude – If available, the GPS latitude for this profile.
•
Column 8: GPS Longitude – If available, the GPS longitude for this profile.
•
Column 9: Depth1 – The depth to the bottom measured by beam number 1 for this profile.
•
Column 10: Depth2 – The depth to the bottom measured by beam number 2 for this profile.
•
Column 11: Depth3 – The depth to the bottom measured by beam number 3 for this profile.
•
Column 12: uVess – The average speed of the vessel for this profile.
•
Column 13: DirVess – The average direction of the vessel for this profile.
•
Column 14: uFlow – The average speed of the water-current flow for this profile.
•
Column 15: DirFlow – The average direction of the water-current flow for this profile.
•
Column 16: StdDev – The standard deviation of flow velocity for this profile.
•
Column 17: DQI – The data quality index for this profile.
•
Column 18: # Valid Cells – The number of valid cells in this profile.
•
Column 19: Q – The calculated discharge for this profile.
•
Column 20: Q Cumul – The accumulated discharge up to and including this profile.
