Hydrocracy: redefining water-centric administrative borders based on hydrological features, i.e., the extent of major rivers, and the irrigation, economic, and fluvial transportation capabilities they unlock.

Less arbitrary than historical borders, and holds great explanatory power over some water-conflicted areas (such as Kashmir)

Interesting. In The Netherlands we have elected water boards, that have responsability for all that has to do with the water in their area. Not sure what it is based on, but many are named after rivers flowing through. 

As for determining the borders, there are the drainage bassins, the areas where all the surface water flows to one focal point. 

Interesting way to reshape the world.

If you think about it, it's also ~ sorting the world's landmass by its z axis, since drainage basins extend from the highest elevation to sea level
