Graphic of water processes and policies for YVR.

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...

Drought is a large-scale problem. Droughts of high severity, long duration, and broad spatial extent happen infrequently enough that ecological and economic dependencies on water are bound to develop during the between-drought intervals. The trick for drought resilient societies is to develop a long-term memory that serves to limit over-enthusiastic exploitation of water resources when water supply is relatively abundant. Most indigenous societies that are highly...

Hydrology is the science of sciences. There is no science that is as dependent on the other sciences and there is no science that is so fundamental to every other science. In fact, it is rarely the case that you would find a dedicated department of hydrology in any university, yet some aspects of hydrology are taught in almost every science department at every university. Water is...

Drought in California,

The droughts that are occurring in California, Puerto Rico, North Korea, Sao Paolo, and India are climatologically driven events, but the droughts of recent times have almost certainly been aggravated by water over-use, mis-use, and abuse. An attractive alternative to the scenarios that are currently playing out around the world is one in which monitoring is in place and provides: water supply statistics (so that planning...
