4) Open up Winriver II and first configure the peripherals

* ADCP - and configure the com port and buad rate that the bluetooth uses for the streampro. Often it is COM40. Always use 115.2 K for the streampro baud rate.
* GPS - if using GPS you need to specify the bluetooth COM port for GPS.
* You should test the port to make sure winriver can communicate with the ADCP and GPS. If you get a blank screen communications are not working properly.

5) WinRiver II set up:

a) Select File --> New Measurement.

b) Enter in the Station data (include the date of measurement in the station name) and click next

c) Enter in any Rating information and click next

d) in the configuration of devices, Winriver II will attempt to talk to the ADCP and should automatically detect it (wait a few seconds)

e) in configuration, If using GPS, check the associated buttons.

f) in the Offsets, enter in the transducer depth (m), this is the distance from the transducer bottom to the water surface. Note that you should align the transducer heads in line with the bottom of the float.

g) enter the magnetic variation at your location

h) Use the default cell size and number of cells if possible, and then enter the max water depth and velocity. The max boat speed should always be equal to or less than the water velocity when making the measurement. The maximum water depth is 2 meters w/ Streampro.

i) enter the water mode.

j) in the recording section, write down the file name prefix, which should be the Station Name and Location and the date of msmst: Example: KadleroshilikR_pipeline_060609

Also check the "Long (YY-MM-DD hhmmss)" in the Use Date/Time in Filename section.

6) Next step is to conduct the following required QA/QC tests:

a) Set ADCP clock

b) Conduct the ADCP test (diagnostic test). Write down in your notes if any tests fail and if they do, try again. Test should be conducted in non-moving water.

c) Conduct a [[compass calibration]] and evaluation if the instrument has a compass (the streampro will have a compass as of May 1, 2010). Compass calibration and evaluation should be less than 2 degrees, and better yet, less than 1 degree. If not, try again, and keep trying until less than 2 degrees.

d) Conduct a [[moving bed test]]. REQUIRED, especially if there is no compass/GPS. It is good practice to do this for every measurement so you can correct the data for a moving bed (moving bed materials also include very fine sediments and organic materials). It is best to do a loop test (i.e go across the river and then come back to the exact same location where you started). Otherwise you can due a minimum of 3 stationary moving bed tests across the river. It will appear as if the boat has moved upstream. Stationary test for 10 minutes (5 minutes if anchored or tethered). If you have a moving bed, it will appear as if the boat is moving upstream. Use the USGS LC or SMBA test to correct.

7) You are ready to begin the measurement and so press F4 Start Pinging. Make sure you have two depth cells (or two good bins) before you start the measurement.

8) Press F5 or Start Transect. Measure the distance from the bank to the starting location where you have 2 good bins with a laser rangefinder. Inside this area, the discharge will will be estimated by the software. Make a note of the channel geometry for these purposes. Wait for 10 ensembles, then proceed slowly across the river.

Four transects are required and must be within 5% of the mean discharge. If you cannot make the 5%, continue to do additional transects. It may be necessary to do your transect diagonally downstream if the velocities are very fast. The key making a measurement is to move the boat slowly! Boat velocity should always be less than the water velocity.

9) At the stopping location (where there are still 2 good bins) hold the boat position for 10 ensembles w/ 2 good bins. To stop the transect press F5 again or Stop Transect. Measure the distance from the ADCP to the bank and enter it in the computer. Then begin the next transect by pressing F5/Start Transect.

10) Press F12 to see the discharge measurement summary

Check to see that GPS is RTK (5) or WAAS (9) w/ the Novatel GPSs.

Check the NMEA string to see that GPS is differential: RTK (5) or WAAS (9) w/ the Novatel GPSs. If you have a (1), you have no GPS, if you have a (2) you have GPS but no differential (RTK or WAAS) correction.
