The following is the list and the descriptions of the equipment conditions at each of the old study sites after some repairs
Datalogger Station
CR10 Datalogger: Yet
to be completed. Program has been reloaded
12V DC Battery:
OK
Photovoltaic cell panel: OK
Pyranometer: Yet to be completed.
Electric rain gauge (tipping bucket): If there is rainfall it is triggered every minute. To calibrate the instrument, the following data have been collected:

The diameter of the bucket is 155 mm (6.10’’). It needs to be cleaned up regularly.
Anemometer: Yet to be completed. For the moment one of its electric wires is not connected
Air temperature and Relative humidity Sensor: Yet to be completed.
Ultrasonic proximity sensor: Yet to be completed.
V-notch weir. Yet to be completed.
ISCO automatic water sampler: Yet to be completed. Collecting tubes are lincked
Manual rain
gauge: OK. The diameter
is 103 mm (4.06’’)
Note: Lot of water plants in the channel, upstream and downstream, to be cleaned up with appropriate tools
Datalogger Station
CR10
Datalogger: Program has
been reloaded. Now it works
12V DC
Battery: New one has
been fixed. Without the
photovoltaic cell panel it will run down fast. Photovoltaic cell panel has to be installed
Photovoltaic cell panel: Still not present
Two stilling well: Yet to be completed

The diameter of the bucket is 155 mm (6.10’’). Rain in-taking area is not perfectly horizontal as it should be. It needs to be cleaned up regularly.
ISCO automatic water sampler: : Still not present
Manual
rain gauge:
OK. The diameter is 103 mm (4.06’’)
Note: Lot of water plants in the channel, upstream and downstream, to be cleaned up with appropriate tools
