Water resources in Romanian Carpathians-genesis, territorial distribution, management. Discussing water resources in Romania implies a twofold approach: water as a sine qua non of life itself and water as an important factor for the development of the contemporary society. Lying in a temperate zone, Romania's water resources are rather modest compared with other countries in Europe. Inland rivers span 78,905 km (referred only to the 4,864 codified watercourses) at an average density: 0.38

To knowledge ground waters are put at 9.62 billion m3/year, of which 6 billion can be used in optimal technological and economic conditions. According to a recent UN statistical report, Romania lists at position 21 among the 34 European. Natural lakes are replenished from precipitation and springs water every year and the reserves are estimated at around 1 billion m3/year and are of local importance for water management schemes. The Black Sea (in the Romanian sector) could become a major source if sea water desalting could be economical.The water resources of the drainage network were calculated on the basis of the mean liquid flow map (scale 1: 500,000) releves picture of river-water resources in the major relief units: the Carpathian, which occupies only 27.9% of the Romanian territory, 65.3% (26.48 billion mc from a total of 40.61 billion m3) of the water is formed and regenerated every year; the hill unit, which includes the Subcarpathians, the tablelands and the piedmont hills, and occupies 42.4% of Romania's territory, only 28.0% of the water volume is formed (11.38 billion m3), of which 8.7% (3.51 billion m3) in the Subcarpathians and 19.4% (7.87 billion m3) in the other two units; the plain unit, which covers 29.7% of the country's territory, the water volume formed there is small (6.7%)
