Hi, my name is Mike Freeman and I'm a hydrologic technician with the USGS office here in Salt
Lake City, Utah.
I would like to take a few minutes to talk about staging an ADV measurement using SWAMI.
Hopefully, you've already seen the SWAMI screencast video "Staging a discharge measurement in
SWAMI" that discusses 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, fill out the information on the time sync.
By selecting the drop down menu you can select "Yes".
Next click the blue 'Time' button to assign a time value to the measurement sync time.
Next use the drop down menu to click 'Yes' to indicate that the instrument was tested.
I would like to point out that temperature comparison measurements with your ADV must
be entered in the "Temperature/Salinity" page.
Avoid the common mistake of entering these values in the 'Environmental Measurements'
task within SWAMI.
Click the 'Temperature/Salinity' button.
Here you can enter the time by clicking the blue 'time' button, manually entering the
time, or clicking the calculator to assign an instantaneous value.
Next you will enter the temperature readings for your instrument and the verification temperature,
made with a separate meter.
You can also enter salinity values and make a comment regarding the measurement.
Once you are done click 'Add' to populate the readings and the comment.
You can make multiple readings at this point.
Once you have completed all your temperature/salinity readings click 'Done' to return to the 'Acoustic
Information' page.
Next we will look at the 'Acoustic Channel Notes' page.
The 'Acoustic Channel Notes" page is where you can make general notes relating to the
measurement while you are making it.
First, enter a title.
The title should include a description such as Station 1, or Edge.
After you have created a title, enter an appropriate comment in the 'Comment Section'.
Here you can write the condition that is affecting your station such as 'Large boulder upstream
of station.'
After you have added the comment, click 'add'.
This 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 thus far.
Leave the 'Acoustic Information Page' open while you are measuring so you can make any
necessary notes related to your measurement.
Select the 'Done' button to return to the 'Acoustic Information Page'.
Once the measurement is complete click 'Done' again to move onto the 'Channel Summary Page'.
Here you will document channel conditions and the measurement location.
The drop downs menus make documenting channel conditions easy.
In this example our Section Location was 'Upstream'.
The section was approximately 40 ft upstream of the gage.'Horizontal Flow' was 'Even'.
For the 'Channel Conditions' the material was 'gravel', the stability was 'firm', the
channel material was 'even'.
For the 'Velocity Description', the velocity distribution was 'standard', and 'steady'.
Once you have finished the 'Channel Description' click 'Done' which will return you to the
'Channel Summary' page.
Click 'Done' to return to the 'Discharge Measurement' page.You will notice that the measurement
is now staged.
At this point you should download the measurement from the ADV using the FlowTracker software,
and process the .wad file in the FlowTracker software.
This will create the .dis file you will need to import the measurement data into SWAMI.
After a quick review of the measurement in the FlowTracker software, right click on the
staged channel, or click and hold the staged channel on your PDA and select the 'Import'
option.
Once 'Import' is selected, a dialog box will pop up asking you to select the measurement
file.
For the SonTek FlowTracker ADV measurement you will import the .dis file from the drop
down menu.
Click on the .dis file and click 'Open'.
Once you've selected the correct file, the file type will be identified for your confirmation
and you may 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.
Confirm all imported data and check the 'Meter Inspected' box to verify that the meter has
been inspected.
When all fields are filled out, click 'Measure' to take you to the 'Acoustic Information'
page.
In the 'Acoustic Information' page you will notice that the information has been completed
during the staging process.
Make any necessary changes and then click 'Done'.
The next screen is the "Midsection Summary" page.
The information populated on this page has been updated with the information from the
.dis file that was loaded into SWAMI.
Verify the numbers that were imported and click 'Done' to go to the 'Channel Summary'
page.
In the channel summary page, verify that you have inspected the meter by checking the 'Meter
Inspected' checkbox and make any changes that are needed.
Once the page is complete, click 'Done' and end the discharge measurement.
Now, this channel is complete and you are back to the 'Discharge Measurement' page,
you can add another channel to the measurement, or if you are done, you can enter your gage
height information to compare the measured flow to the rated and shifted flow.
For this measurement, our stage is 2.68 ft.
At this stage, the measurement plots 5.2 percent from the base rating and -2.1 percent from
the shifted rating.
After the gage height has been entered, click 'Done'.
You will be asked if you want to end the discharge measurement.
Click 'Yes' to end the discharge measurement.
Your last task is to fill out the measurement summary page.
Typically, I enter the measurement number.
If the measurement number is unknown, you can select 'Auto Sequence' for the measurement
number and the next available measurement number will be assigned in SiteVisit.
Rate your measurement, determine your base flow conditions, fill out the gage height
information and populate the start and end times.
Lastly include any measurement remarks.
You have already made notes during the measurement, but you may still need to make additional
notes about the measurement.
This could include comments about the measurement rating, any gage height issues or check measurements.
Once you have populated all fields in the measurement summary, click 'Done' to end the
measurement.
Now, your measurement is complete.
