Hi there, my name is Nick Stasulis and I'm a hydrologic technician with the USGS office
here in Augusta, Maine.
I'd like to take a few minutes to talk about staging a moving boat ADCP measurement in
SWAMI.
Hopefully, you've already seen the SWAMI screencast video that discussed staging a measurement
in general.
If not, review that video before finishing this one as it provides some good introductory
information.
In the general staging video we indicated that we would like to stage a measurement
in SWAMI, which brings you to the acoustic information page, where we are now.
The information on this page is fairly self-explanatory, but I'd like to make a few points.
First, this page is where you take notes as you are preparing for and completing the discharge
measurement.
Here, you make notes on when the time was synced, complete the ADCP test, calibrate
and evaluate the compass, note what model of GPS was used and what boat or motor was
used.
The moving bed drop down is asking whether or not there is a moving bed condition, not
if you did a test.
I'd like to point out that temperature comparison measurements with your ADCP must be entered
in this temperature/salinity page, not in environmental measurements.
In the temperature/salinity readings page you enter the time of your comparison, the
instrument reading and the verification reading.
Salinity values can also be entered, as well as comments relating to your comparison.
Once complete, hit the add button, and notice that multiple readings can be added here.
Selecting done will take us back to the acoustic information page.
Clicking acoustic channel notes will bring us to the acoustic measurement notes page,
where you can make miscellaneous notes relating to the channel.
Enter a title for your note, examples might include edge, transect 1, loop test or others,
then make the comment.
Selecting add will store the comment below.
You will also notice the number of characters remaining in the SiteVisit comment field based
on the notes you've made so far.
Selecting done here will take us back to the acoustic information page.
Leave this acoustic information page open while you are measuring so you can make any
necessary notes.
Once the measurement is complete, select Done and move onto the channel summary page, where
you can document channel conditions and the measurement location.
The drop downs make documenting channel conditions pretty easy.
Selecting done will bring us back to the discharge measurement page, where we can see our staged
channel, which still needs discharge information.
By right clicking on the channel, or clicking and holding on the PDA, we see the options
to edit or delete the channel, as well as import or summarize data.
Summarizing allows you enter basic measurement information and is not used with ADCP measurements
as importing is required.
Once import is selected, a dialog box will pop up so you can select your file.
For WinRiver II measurements, you should select the mmt file, for SonTek measurements you
would import the .dis file.
Once you've selected the correct file, the file type will be identified for your confirmation
and you may or may not see other warnings that you should address as needed.
On the channel information page you will notice many fields are filled out already from the
imported data, simply select a deployment method and confirm the suspension method.
Selecting measure will bring us back to the acoustic information page, where you can make
modifications, if needed.
Next is the ADCP measurement summary page, with your measurement totals.
If you had a moving bed correction, be sure to confirm the correct discharge was imported
under the correction page.
In this case, no correction was applied in WinRiver II, so no correction information
was imported.
If a moving bed correction was applied in WinRiver II or RiverSurveyor Live the measured
and corrected discharge, as well as the correction method, would be filled out automatically,
though you can manually apply a moving bed correction here too.
Next we are brought to the channel summary page, which you likely filled out already.
Now, this channel is complete and we are back to the discharge measurement page, where we
can add another channel to the measurement, or if we are done, we can enter our gage height
information to compare the measured flow to the rated flow.
In this case, we see the measurement plots -0.4% percent from the base rating and the
same from the shifted rating as there is no shift in effect.
Our last task is to fill out the measurement summary page.
Typically, I select auto sequence for the measurement number, though you could enter
the number if it was known.
Rate your measurement, fill out the gage height information
and populate the start and end time by clicking the appropriate title, which will bring in
the times from the imported ADCP file.
Don't forget measurement remarks.
You may have made notes during the measurement already, but you may need to make additional
notes here about the measurement rating or gage height issues.
Now, our measurement is complete.
