Alberto Montanari (GS) is a distinguished Italian colleague, and the editor in chief of Water Resources Research, one of my favorite hydrological journals. He is also very active in the IAHS especially for what regards this hydrological decades named Panta Rhei.
We do have a different approach on many topics, and different attitudes towards modelling. Nevertheless one cannot deny that his production is important and interesting.
However, this time I was attracted by the fact that he is putting a lot of his material on-line making available to students the videos of his class of advanced hydrology and hydrology construction. Other videos are available on his youtube page.
