[:ja]セルゲイ・クド-スべルチコフ宇宙飛行士がISSから撮影したアルメニアのセヴァン湖です。
セヴァン湖はアルメニア・ゲガルクニク地方にある同国最大の湖で、大規模な湖としては世界で最も高地にあるものの一つです（海抜約1900m）。一部の水のみ北西のフラズダン川へ流出し、これはクラ川に流入してカスピ海へ注ぎますが、乾燥地帯にあるため90%の水は直接蒸発しています。ソ連時代にはフラズダン川を通して灌漑に大量使用されたため、水量が大幅に減ってしまいました。水位の低下により、セヴァナヴァンク教会のあるかつてのセヴァン島は、現在半島になっています。

[Earthview Wonders] No.1213: Lake Sevan, Armenia🇦🇲
Astronaut Sergey Kud-Sverchkov captured from ISS Lake Sevan, Armenia.
Lake Sevan is the largest body of water in both Armenia and the Caucasus region. It is one of the largest freshwater high-altitude (alpine) lakes in Eurasia. The lake is situated in Gegharkunik Province, at an altitude of 1,900m above sea level. The total surface area of its basin is about 5,000km2, which makes up 1/6 of Armenia’s territory. It is fed by 28 rivers and streams, and only 10% of the incoming water is drained by the Hrazdan River, while the remaining 90% evaporates. The lake provides some 90% of the fish and 80% of the crayfish catch of Armenia. Sevan was heavily exploited for irrigation of the Ararat plain and hydroelectric power generation during the Soviet period. Consequently, its water level decreased by around 20m and its volume reduced by more than 40%. Its sole major island (now a peninsula) is home to a medieval monastery.
