Abstract
Rivers have long been the focus of attention in international law, as natural boundaries or as routes for navigation and trade between states. Gradually, other uses emerged, such as fishing, energy production and agricultural and industrial uses. Based largely on river basin regimes, international law on transboundary water resources evolved over the course of the 20th century. Interactions between local, regional and universal levels will help us to understand the specific features of the rule of law in this field.
