摘要

Algeria covers an area of 2 381 741 km~2. It has a population of about 43 million (2018/9 estimate). Annual average precipitation varies greatly, from more than 1200 mm in the coastal basins, to less than 50 mm in the Sahara desert. The total mean annual precipitation volume is 100 km3, with total runoff of around 12.4 km~3. The Ministry of Water Resources is in charge of national policy in the field of water resources. There have been no changes in the sector since our 2015 report. Access to a drinking water supply is available to 98 per cent of the population. Per capita water consumption is about 180 1/day. There are about 80 large dams in operation, with a total storage capacity of more than 7.57 × 109 m~3. Of these, 57 are embankment dams. Among the dams completed in the last few years are: the 93 m-high Kef Eddir earthfill dam on the Damous river; the 75 m-high Draa Diss rockfill dam on the Madjez river; and, the 76 m-high Mahouane dam on the El Guessar river. All are for drinking water supply and irrigation. There are 400 small reservoirs in operation, with a total storage capacity of 7.5 × 10~6 m~3, irrigating a total area of 18 000 ha.
