QiQuac Mobile
1.0 Introduction The QiQuac Mobile app is Fathom’s attempt to move from the stone tablets of yesteryear and into the world of machines that listen to us and control our thoughts. But you’ll find no such subterfuge in the QiQuac…
Fathom: Resonance
Hey Fathomlanders, how’s it going? CoVid got you down? Need some pick-me up? Well Fathom has just what the doctor ordered! A full dose of tech-talk and quasi-science-fiction. Quasi-Science-Fiction and Cultural Artefacts This just in! For those of you clambering…
Fathomland: A New Dawn
You’ve been travelling for days. After escaping from the perils of King Nick’s Poetrysseum and following the softer moss north, you found yourself in the rarefied air of Grustland and the Great City of Oz. In a fit of insp/despiration,…
A "Wales" of a Good Time
Sometimes we get bogged down by the fishbowl effect. Looking around your fishbowl at the other fish as they look back at you. You swim around in a circle, they do the same, you’re staring at them again a second…

The Future of Hydrometrics
I have traveled to the future. In the future, we will all drive on the left hand side of the road. Gangs of sheep and cattle will roam with impunity over bright green pastures. The All-Blacks will not dominate international…
NORDIC CREEK AT THE OUTLET OF NORDIC GLACIER (08NB020) and SUNDRY SUMMER BUSINESS
Nordic Creek AutoSalt Site Wagner blasted in our headsets as Mark the pilot and I crested Hermit Ridge and the full spectacle of the mountain scene fell on my retina. I struggled to comprehend it all. Ventego Lake, a beautiful…
Performing a Salt Dilution Gauging using QiQuac
Introduction This article will lead you through a salt dilution flow measurement using the QiQuac system. It is the same procedure using any other EC and temperature system, but the diagnostics and calculated Q will not be available in real-time. …
Quantifying and Controlling Error in Salt-Dilution Measurements: Sources of Uncertainty
This article is a more detailed examination of the Sources of Uncertainty referenced in Quantifying and Controlling Error in Salt-Dilution Measurements. It is based on material presented most recently at the CWRA Conference in Lethbridge, Alberta, Canada, April 2017 (Lethbridge_Salt_Dilution_Uncertainty_V0.9). Injection…
Derivation, Uncertainty, and Variance of the Calibration Factor used in Salt Dilution Flow Measurements
This article is based on material presented at the AWRA Conference in Virginia, USA, Nov 2014 (AWRA_Salt_Dilution_CFT_V0.3) which was co-authored by Gabe Sentlinger (ARD), Mark Richardson (UBC), Andre Zimmerman (NHC), and John Fraser (ARD)†. Abstract The Calibration Factor – Temperature…
Quantifying and Controlling Error in Salt-Dilution Measurements
Introduction Salt-Dilution Instream Q (SDIQ) a method in which a known mass of salt is injected upstream of a conductivity probe and the conductivity signal measured. The technique has been used for decades. An introduction to the technique is described…
