Abstract

The purpose of this work is to illustrate the didactic usefulness of the Congo-Nile Divide. The cartographic analysis (at the appropriate scale) of some important geographical objects allows to analyze the action of unification of the territory, action carried out by the objects themselves. This action, in fact, even when it seems to divide, generates a connecting hinge (as in the case of the Congo River, that partially marks the border between the two States of the same name). Inspired by Buache river basin theory, we could, therefore, propose a theory of unifying river basins.
