Very complete exposition on the state of knowledge of the period concerning rivers, streams and waterways, their flow, on alluvium, riverbeds and how to change them, their slope, the mouth to the sea... Frisi furthermore cites all the studies and works that have been written on this domain. The mathematician author is a scientific observer, not a commentator, and it is in the field and carrying out experiments and calculations himself that he forms his theories and invalidates those that have already been made. The author dwells particularly on the case of the course of the Primaro, which was to concentrate the waters of the Po and other rivers.
