Romania's water resources and their use

In relation to population Romania's water supplies are quite modest. They are provided by the rivers, which meet 89% of the present demand (48% from the Danube and 41% from the interior rivers), and by the underground sources which account for 11%. Mean specific runoff is 4.57 1/sec. km² but there are significant variations through both space and time. The factors responsible for both maximum and minimum runoff are discussed and particular reference is made to the floods of 1970. Load and turbidity levels are also discussed. Underground water sources are described and a review of demand gives particular attention to hydroelectricity and water transport. Principles for future management of water supplies are summarised in conclusion.
