This post is really just an excuse to share a pretty cool animation. But first some background.
I’m currently reading “Water Resources” by Shimon C. Anisfield. It’s been a fascinating and enlightening read so far. In the chapter titled “Water Availability and Water Use” he makes the point that some regions get a fairly constant amount of rainfall over the course of a year (e.g. northeastern US), while other regions have very distinct wet and dry seasons (e.g. India). The reference used to illustrate this point is very cool: global-scale animation of monthly rainfall from 1979 to 1999.
This seasonal variability means that water has to be stored somehow and this is a very big challenge for modern-day water managers and has always been a huge challenge for civilizations over the millennia. In upcoming weeks we’ll discuss how some of the methods used to manage this problem have created even bigger ones.
