My draw is also here below for free usage (I have also the image for the Hortonian runoff though).

Since 10 year, the Saturday after the EGU meeting, Guenter Bloeschl (GS) organizes at TU Wien a meeting of hydrologists called the Wien Hydrology Symposium. This year among the guest there was Thomas Dunne (GS) who talked about fluvial geomorphology. Tom is universally known for his work as hydrologist and geomorphologist (both of them) and students will realize that saturation excess mechanism of overland flow formation take its name from him as Dunnian runoff. Here you can find a picture of him with my own representation of "his" process.
