I’ve been meaning to put together a photo gallery of installations. So here it is (if the stand looks off-kilter, it’s just the photographer and not the stand). Please note that Rating Curves have not been developed for all sites. Where RCs are presented, they are the most recent RC from the Salt Portal, and may contain only a few days of data, or a few years. Where multiple rating curves have been developed over time, a more elaborate figure is presented. All sites are a bit different and we will work with you to find the best solution for your site, including finding a local supplier of tank and the best telemetry solution.
Blaney Creek in the UBC Malcolm Knapp Research Forest, B.C. Canada (Dec 2022)
The UBC Blaney Creek AutoSalt system is unique. It features wifi telemetry and 3 downstream monitoring stations, much like the Eskay Creek site, described below. Injections made at the upstream site can be measured at the three downstream locations, so long as they are not losing reaches (none are expected to be) since salt dilution will only measure increases in flow (increased dilution) moving downstream. So far the results are very promising, with 50 injections spanning the range from 0.183 m3/s to 10 m3/s. Because we know the distances between sites, we can also work out a channel reach Q-Velocity relationship. (TBD)
Noosgulch River near Bella Coola, B.C. Canada (March-July 2022)
We installed the “Backpack” version of the AutoSalt system on a rock ledge, just upstream of a very deep canyon. The canyon is 1km long and emerges near the bridge, shown in the bottom/right most photo. The aluminum pipe showing the locatoin of the T-HRECS DL (EC.T Datalogger) can be seen on on the right (river-left). The flows range from 2-75 cms here throughout the year and given the long canyon, required 400g/cms to measure accurately. This means that for the 40cms measurement, 16kg was required, or 80 litres of brine at 20%. This requires careful management of the brine, which does not last very long for large flow events. We installed a secondary tank connected by a hose, as well as an upstream EC.T meter to better track the BG EC.T during an SDIQ in July 2022. This system also has a Neon satellite telemetry unit, and two EC.T probes measuring pumped brine conductivity and temperature.
There has been 92 measurements at this site so far, but the hydraulic control changes frequently. So far we are working with 3 rating curves since March 2022. This has been a challenging site, but the AutoSalt has performed well.
Krokbräcke Creek near Fjällbacka, Sweden (May 2022)
This lovely little stream features very large pools compared to the flow when we installed this in May. We installed three downstream EC.T probes at intervals of ~100m to capture a range of flow events.
Krockbracke Update! A storm came through Fjällbacka on Nov 7, 2022 and we were able to measure up to 2-3cms, although there is evidence of either a) incomplete mixing or b) fouled sensors. This rating curve has had a few outliers labeled anomalous.
