I discovered this Sankey diagram in an article by Gutiérrez-Martín, C.; Borrego-Marín, M.M.; Berbel, J. on ‘The Economic Analysis of Water Use in the Water Framework Directive Based on the System of Environmental-Economic Accounting for Water: A Case Study of the Guadalquivir River Basin” (published in Water 2017, 9, 180, open access article licensed under Creative Commons (CC BY 4.0). The Guadalquivir river basin is in Andalusia, Southern Spain.

The authors note that Sankey diagrams for water flows in a river basin or catchment area are useful because they show “at a glance, several aspects of the water cycle such as economic units, abstraction, supply, use, consumption, and returns to environment (soil water not included). In studying water use pathways, Sankey diagrams illustrate quantitative information about flows, their relationships, and their transformations.”

We see water taken (“abstracted”) from surface or groundwater by water supply companies and other users, distribution and water consumption by sectors, water flows ‘lost’ to the atmosphere and return of water to the environment.

Flows in this diagram are in hm³ (cubic hectometres). Note that they decided to use another scale for water used for energy generation (x 10 hm³) since otherwise the yellow-beige would be 10 times wider and maybe spoil the whole diagram.

The diagram has a top-down orientation and numerous loops and flow feedbacks, in contrast to the typical distribution diagrams (aka alluvial diagrams). It is well structured, nicely crafted and pleasing to the eye. Definitely on my top 10 list for 2018.

    Today, I went to the beach front with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell someone!
