The Paperless Acoustic Measurement - SWAMI with Acoustics
SWAMI with Acoustics Nick Stasulis and Joel Dudley Maine Office New England WSC Burl Goree Ruston LA WSC Webinar Presented: May 21 and 30, 2013
Topics What is SWAMI and Current Usage SWAMI Setup/Configuration Files Staging/Importing Acoustic Measurements Loading SWAMI files into SiteVisit Viewing SWAMI files with style sheets and in SiteVisit Archiving paperless measurement files Help/Resources
What is SWAMI? (Surface WAter Measurement and Inspection) Field application to record all aspects of a Surface Water site visit Used on PDA or Windows XP/7/8 device (SWAMI and SWAMI_PC) Used to record sensor readings, site observations, and allows for direct collection of AA/pygmy measurements Used to record notes associated with acoustic measurements (ADCPs and acoustic point-velocity meters) and allows for import of associated acoustic data
Outputs data to a HydroML file, which can be loaded into Site Visit via dragand-drop or the loader. From May 2012 to April 2013 Of 36, 760 ADV Qms 25,280 (~69%) collected with SWAMI or SWAMI_PC Of 19,835 ADCP Qms 13,026 (~66%) collected with SWAMI or SWAMI_PC For ADVs SWAMI used 72% of the time, SWAMI_PC ~28% of the time For ADCPs SWAMI and SWAMI_PC used about equally ADVs imported about 50% of the time ADCPs imported about 72% of the time
SWAMI Setup - Scripts Scripts are available to pull WSC-specific information to use with SWAMI Scripts pull information such as active station names/numbers, current ratings/shifts, station specific sensor lists, velocity meters configured in SiteVisit, and previous site measurements It is recommended that these scripts are run daily. The updated files should be synchronized to field devices prior to any field visits.
Not having up-to-date output files from the configuration scripts can lead to issues within SWAMI, but its more likely to create files that will fail to load into SiteVisit For acoustic
measurements- ensure the meters.txt file includes each ADCP/point-velocity meter by serial number Site Information Sites taken from stations.txt file including all active
stations retrieved from NWIS or SIMS Designated email recipient of SiteVisit loader results Overall site visit comments; multiple comments areas throughout SWAMI at various task levels
Weather Description Wind direction required if wind magnitude is not designated as calm For ADCP measurements, be sure this reflects the measurement location, not gage location - could
support/confirm change to top extrapolation Options: Upstream wind
Downstream wind Cross stream wind Swirling/Variable wind Site Visit Tasks Starting a New Channel New Channel Measurement hasnt started
This should be standard approach when making an acoustic discharge measurement. Used to stage an acoustic measurement fill out notes while making a measurement and BEFORE importing the measurement file. Import Channel Measurement is complete
Can be used if SWAMI wasnt available during measurement and its now finished Use with ADCPs should be RARE and is not recommended! Starting a New Channel Pop up window appears when selecting ADCP Method or
Midsection > Wading > ADV Staging a measurement allows you to fill out notes and measurement information in SWAMI during the measurement Acoustic Information Moving Bed is the only required field
Moving Bed? asks if a moving bed was indicated (LC, SMBA) not if a moving bed test was performed Acoustic Information can be filled out while staging the measurement or after the measurement file has been imported
Typically, this page will be active during entire measurement Gage readings can be entered using the SensorsQE menu option Temp/Salinity Readings Temperature comparison readings for
ADCP/ADV should be documented here and NOT in environmental measurements Temperatures can be entered in F or C, just be sure they are consistent! Multiple readings can be entered, which could be useful when doing salinity profiles across the channel. Distance and width can be entered in
the comments. Acoustic Measurement Notes Examples of Titles: General, 001, Transect 001, T1, LC Test, etc. All comments entered here are put into overall measurement comment
field as this is the only place available in Site Visit. Channel Summary Channel Summary page appears after finishing with Acoustic Information page Discharge Measured will be populated once measurement
file is imported or summarized. Information can be filled out while staging the measurement or when the measurement file is imported. Loading Acoustic Data
Channel is staged has notes and documentation, but no discharge. Summarize manually enter flow info Useful to make notes for FlowTracker and manually enter summary if you cant download the unit in the field
Import load in acoustic measurement from file Import Options AquaCalc CSV file FlowTracker, RiverSurveyor Live, RiverSurveyor Stationary Live DIS file WinRiver II MMT file (preferred) Will import transect notes, measurement notes, ADCP tests, compass cal info WinRiver II HydroML (not recommended)
Measurement notes, ADCP tests, compass cal info NO transect notes MUST create new HydroML each time configuration changes are made SxS Pro XML summary file Checks During Import Channel Information
Fields will automatically be filled in with imported data from measurement file. You will need to fill out Deployment Method and check the Suspension Method Other fields may need to be populated if information is not available from the imported
measurement file Check/Edit Acoustic Info/Notes ADCP Measurement Summary Corrections for moving bed tests DONT use adjustment anymore!
Dont adjust discharge for moving bed conditions here. Use correction in previous window!! New Acoustic Fields Many of the new acoustic fields like the temp/salinity readings, the moving bed correction info, etc do not have a place to be stored in the NWIS database, so they are only viewable using the style
sheet applied to the SWAMI file Importing into SiteVisit Locking Down Files in SiteVisit Address any warnings in SiteVisit For example, may need to calculate velocity if moving bed correction was applied
Save and lock SiteVisit Using the Loader Another option is the submitsvfr command in a Unix terminal window. For help setting up the loader:
http://nwis.usgs.gov/nwisdocs5_0/SiteVisit/SV.user.book.html Making updates to a Site Visit Now that the SWAMI data are in Site Visit where are updates made? Two common ways to handle changes Update the SWAMI file, delete whats in the database and re-load the updated file
Leave the SWAMI file as the field copy and update Site Visit with the current information Update SWAMI SWAMI file and SV match Can lose info added to SV Recommend saving original SWAMI file, creating new edited SWAMI file Preserves field data
Preserves any changes to the visit in SV SWAMI file and SV dont match Update Site Visit Either way, any changes should be well documented!

Archiving Acoustic Data All data associated with a measurement must be stored and archived so the original data and final discharge are preserved Includes: Archiving electronic and/or paper notes and summaries Archiving data files Entering measurement information into the NWIS database Best Practices
All measurement data should be moved from field computer/backup media to office server within 48 hours of returning from field Once the measurement is finalized, store it permanently in a manner that prevents accidental modification/deletion All ADCP data (including compass cal/ADCP test) associated with individual measurement should be stored in a folder unique to that measurement Archiving Acoustic Data When using electronic field notes:
A summary of the final discharge must be stored in either NWIS (such as importing the final measurement information into SWAMI) or saving the measurement summary from the processing software to a pdf file and storing it with the ADCP data The output from any utility programs used (LC, SMBA, Extrap, etc) should also be stored electronically with the ADCP data An ADCP-specific style sheet has been discussed to standardize the output format of the data stored in Site Visit
Ensure the original SWAMI file is archived on the local project directory once imported Still no policy on SWAMI? we are still figuring this out and are going to be doing so for awhile to come as we implement AQ and continue to develop our field apps(there are) some people who feel we should have it all figured out, but it is important to be honest about (that it may be a while before we figure it out)
Folks dont want a solution that HQ figures out in any case. We remain a field driven organization and we work these things out collectively over time. Its messier than we want and frustrates us at times, but in the end we get to a much better final answer. The important thing in all cases is to understand the principles involved, which have not changed. Were just continuing to learn how to apply those principles to new types of instrumentation and in a fully electronic environment ..there comes a time when it is important for HQ to take the best of what we have collectively learned and develop a uniform policy or practice. Id like
to think we are getting close to that with SWAMI, archival, etc. (is past due no doubt in the minds of many). Resources Field Computing Integration and Support (FCIS) Website: https://collaboration.usgs.gov/wg/FCIS/SitePages/Home.aspx
