Fresh waters of Europe

Origin and formation of waters The hydrosphere originates from the bowels of the earth through the volcanic gorges. It is close related to the processes in the atmosphere.

Types of fresh waters in Europe Surface waters riverslakes Ground waters artesian karsts mineral

Ground waters ● Artesian - waters between two waterproof layers ● Mineral- water naturally impregnated with mineral salts or gasses ● Karsts – underground waters reach of CaCO³

Rivers

Europe’s three largest rivers, the Volga (1), the Danube (2) and the Dnepr (3), drain one quarter of the continent. However, they are relatively small by world standards; their catchments ranking 14th, 29th and 48th, respectively.

Water abstraction

Water use by sectors

First main problem Water scarcity and drought Measures: ● The use of economic instruments, such as water pricing and metering ● Water-reuse and recycling ● Increased efficiency of domestic, agricultural and industrial water use ● Water saving campaigns supported by public education programmes

Second main problem Floods During the last five years in Europe major damaging floods Since 2000, floods in Europe have caused: ● at least 700 deaths, ● the displacement of about half a million people ● at least 25 billion € in insured economic losses.

Third main problem Pollution

Prevention Strategies ● The Urban Wastewater Treatment Directive (91/271/EEC) ● The Nitrates Directive ● The Bathing Waters Directive (76/160/EEC & 2006/7/EC) ● The Water Framework Directive (WFD; 2000/60/EC).
