2. BARAJE - DEFINIRE


The International Commission on Large Dams (ICOLD) maintains a Register of Dams in the World. For a dam to be considered large and be included in the

register it must have a height of 15 meters or 10 to 15 meters and store more

than 3 million cubic meters of water in the reservoir. The dams are listed by

country and include data such as the dam name, year of completion, dam height,

reservoir capacity, area of catchment (drainage area), the purpose, installed electric

generating capacity, mean annual electricity energy produced, irrigated area,

volume of water stored for flood protection and number of people affected by

resettlement. The world data as of 2000 indicates that there are about 50,000 large

dams in operation. Embankment dams are the predominant type followed by gravity

and arch dams.

50 000 baraje au peste 15 m si/sau acumuleaza mai mult de 3 mil. m3 mari baraje

Peste 100 000 baraje acumuleaza peste 100 000 m3

Exista cateva milioane de baraje cu acumulari sub 100 000 m3.

Capacit. totala de acumulare cca 7000 km3, din care 98% realizata de marile baraje.

Suprafata totala a acumularilor este cca 500 000 km2, 1/3 din suprafata totala a lacurilor naturale aleTerrei.

95% din total baraje si acumulari dupa 1950.

50% din totalul mondial al capacitatii de acumulare este realizat printr-un numar de doar 100 acumularifoarte mari, fiecare cu cel putin 10 km3;

40% din totalul mondial al capacitatii de acumulare este realizat printr-un numar de 2500 acumulari;

cca 40000 baraje mari realizeaza acumulari cu o medie de 5 106 m3.

600 baraje au H > 100 m;

2000 baraje au H = 60100 m;

10 000 baraje au H = 3060 m.

50% dintre barajele mari au H < 20 m.
