LAA System Sankey Diagram

LAA System Sankey Diagram

Sankey diagrams are a specific type of flow diagram, in which the width of the arrows is shown proportionally to the flow quantity. They are typically used to visualize energy or material transfers between processes. In the above Sankey diagram, the leaders on the left joining the vertical line represent the sources of the LA Aqueduct water and the arrows going out on the right side show the sinks or losses occurred in the process. The above diagram is still a work in progress as the line weights have not been properly evaluated according to the quantities they represent. This diagram was developed over a week and will be further worked on to develop a final version of the Sankey diagram after all the sources and sinks have been calculated. The circles shown in the center represent storage units such as reservoirs, lakes and a few sections of the aqueduct. The light blue leader lines to the left currently represent the quantities of water being pumped in to the Los Angeles aqueduct and the right side focusses on water lost from the LA Aqueduct system in the form of evaporation, groundwater recharge and water that is let into the Lower Owens River Project.
The main principle behind a Sankey diagram is that the evaluations of both the sides should equal each other and both are supposed to match in value. I think Sankey diagram is a very efficient way to convey something in a single visual and having one created for the LA Aqueduct is definitely something that will attract the viewers as it is not complicated and easier to understand for everyone. If given an opportunity, I would definitely like to work on this Sankey diagram in the future and produce a final version with the help of graphic design students.
