The World Economic Forum has ranked the Global Risks for 2018. With the single exception of cyber-security, water is a key factor in the seven other top-ranked high-impact and high-likelihood risks....
Water has always been important. The perception of its importance is closely linked to episodes of too much, too little, or the wrong quality. Climate change, urban growth, and agricultural intensification are just three examples of pressures that are contributing to an unprecedented global awareness of the importance of water....
A reverse evolution in streamflow measurement technology is underway. In the beginning, stream velocity was measured by putting floats in the current and measuring the transit time of those floats over a known distance. ...
Canada has an abundance of freshwater. Our belief in this abundance is deeply embedded in our culture, so much so, that a recent survey shows that Canadians are not inclined to spend tax dollars on water. However, the evidence doesn’t justify our confidence....
The North American Stream Hydrographers (NASH) hosted a Q competition at the Alberta Irrigation Technology Center (AITC) in Lethbridge, Alberta on June 8th. However, this wasn’t a typical flow regatta....
We usually report water quantity information as a volumetric rate (e.g. m3/s); we usually report water quality information as a concentration (e.g. mg/l); and we usually report precipitation as a length (e.g. mm). But we don’t have to. The mass of water is related to its volume by its density which, conveniently, can be assumed to be unity (1). This means that we could just...
