2013 ADCP Extra Guidance

I think this is from a USGS document (added 4/30/2013) relates to WinRiverII 2.10 bugs:

-known issue: Rio Grande compass evaluation not stored if the "close" button is pressed after total error reported but before the "evaluate" and "calibrate" buttons are re-enabled. There is a 2-3 second window after the total error of the evaluation is reported, during which if the close button is pressed, the evaluation will not be stored in the QA/QC node. Workaround: wait until the "evaluate" and "calibrate" buttons are no longer grayed out before closing the compass calibration/evaluation dialog window. This issue is likely also in previous versions.

-known issue: When using GPS as reference and any moving bed tests are checked that indicate a moving bed, the Q Measurement Summary printout will still display the “Discharge Method” for the moving bed correction and “% Correction” of the moving bed discharge applied to the bottom track. The heading for the discharge columns in the transect summary table is also erroneously labeled "MBT Corrected Discharge". The DGPS referenced discharge is correct and this does not affect any other items on the printout. Workaround: If GPS is used as reference uncheck any moving bed tests so that their potential corrections to bottom track are not listed on the Q Measurement Summary printout.

-known issue: When multiple stationary moving bed tests are completed, checked, and some MBT indicate a moving bed correction is needed, if there are MBT in portions of the river without MB that result in these MBT having a slight downstream (negative distance made good), any slightly negative MBT will not be used in determining the proportional correction.

-known issue: When using the internal SMBA corrections, if there is even very slight upstream movement for the moving bed test a correction will be applied if the moving bed test is checked. Typical best practice is to only apply a correction if the moving bed detected is greater than 1% of the mean flow speed. Workaround: uncheck any moving bed tests when no correction is desired.

-known issue: If using an external heading sensor and english units, WRII erroniously applies a English to Metric conversion to any entered External Heading Heading Offset. Workaround: Offset, Compass, Beam3 Misalignment for aligning any external compass with ADCP. This issues is likely in all previous versions of WinRiver II.

-known issue: Entering a Salinity or Speed of Sound in WRII no longer applies any corrections to velocity when using a RiverRay. A correction should be applied to vertical RiverRay velocities. No workaround needed, should not significantly affect discharge.

- Changed default for "Use 3 Beam Solutions for WT" for ALL instruments to True/Checked. This changes how data will be processed by default for Rio Grande ADCPs. StreamPro ADCPs force four beam solutions in software, so this setting has no effect on StreamPro data. The default for RiverRay ADCPs was already "Use 3 Beam Solutions for WT". If using only 4 beam solutions for WT is desired, this option needs to be changed for each measurement.

- Fixed ISM (StreamPro and New RiverRay) compass calibration dialogs and reports.
