This is the lecture I gave at the second Summer school on Water Resources that I co-organised. The lecture was recorded in video and should be made available soon, together with the other lectures.
The lecture can be considered an expansion of the talk I gave at Ezio Todini's symposium with more details and, hopefully, more clear explanations. The presentation is, as usual, available on slideshare, and you can get it clicking on the image below.
The presentation mainly use a paper by Cordano and Rigon, 2008 to obtain various degree of simplification of the Richards equation. The scope (especially for what regards the Todini's symposium version) was to show that many approaches currently used derive, in fact, from a simplification of Richards, and there are not very much reasons to shoot to it as unphysical, at least if this is subsequently followed by the use of one of its simplifications.
However, the slides cover also a discussion over the time scales of flows in hillslopes, and the relative timing of vertical and lateral infiltration.

will follow soon
