Personnel: Douglas Alden, Hillary Beckmeyer, Nick Ellis (DWR)
Installation notes pulled from 2022-10-02 Russian River Trip Debrief
- 0830 - Met Nick Ellis (DWR) at parking lot near Park entrance and headed up to site.
- 0900 - Started install
- Dug two three foot deep holes for enclosure and sensor mounting.
- Dug one 30” hole for 2” tipping bucket pipe
- Placed a 2” sch 40 galvanized pipe in each hole. DWR procedure is to fill holes with dry concrete and then pour the recommended amount of water (from bag directions) over the top. Top of concrete is a few inches below soil level to leave a well. Three bags were used in each hole. It took a long time for all the water to be poured into wells ~45 minutes.
-
- Unistrut was attached to poles to provide alignment. It is probably easier to not do this and align each pole separately.
- 1000 - Started on soil pit.
- Soil Pit
- Soil surface was covered with dry annual grasses.
- Pit was dug deeper than 1 m.
- Crumbly dirt with some clay down to 35 cm. At 35 cm a broken rock layer was encountered.
-
- From 50 cm to the bottom soil was heavy clay.
- It took 2 hours to dig the pit.
- Sensors were installed flush with side of the pit at 1m, 50cm, and 25 cm.

- DWR inserts portion of cables in the ground in stainless steel expandable sleeving .
-
- All cables were run from the soil pit through the sleeving and into conduit. They do not terminate the ends of the sleeving. Heat shrink tubing could be used to terminate the ends over the wire for a cleaner install. The conduit was trenched to enclosure. The end of the flex conduit was wrapped with electrical tape. Wrap of tape extended beyond and then was pushed inside to protect cables from rough edge of conduit.
-
- Water was poured over the hole as the soil was shoveled back in to get clay chunks to recombine into a solid mass.
- Sensors and Enclosure
- All cables are run through flex conduit into the bottom of the enclosure and are cut to length and wire to the datalogger.
- DWR uses a SunSaver10 solar charge controller.
