The daemons of water times

This that you find on Authorea is an elaboration of what I used with my students to teach them what residence times and travel times are in catchment hydrology. Probably I can expand it to be more comprehensive of all the aspects but for the moment it can be a starting point.

I introduced three fictional characters to talk about of the perspectives we can have on the kinematics of water parcels, the little daemons She, He and They. She records what happens inside the catchment. He look at the boundaries. They makes calculations. If you are interested in these stories, click on the figure.
