Lake Hāmūn ((ペルシア語:دریاچه هامون) ''Daryācheh-ye Hāmūn'') or Hamoun Oasis is a term applied to wetlands in endorheic Sīstān Basin on the Irano-Afghan border. ''Hāmūn'' is generic term which refers to shallow lakes (or lagoons), usually seasonal, that occur in deserts of southeast Iran and adjacent areas of Afghanistan and Pakistan as product of snowmelt in nearby mountains in spring. The term Hāmūn Lake (or Lake Hāmūn) is equally applied to Hāmūn-e Helmand〔(Geonames website )〕 (entirely in Iran), as well to shallow lakes Hāmūn-e Sabari and Hāmūn-e Puzak, which extend into territory of present-day Afghanistan with latter being almost entirely inside Afghanistan. The Hamun is fed by numerous seasonal water tributaries; the main tributary is the perennial Helmand River, which originates in Afghanistan Hindu Kush mountains. In modern times, and prior to the existence of the dams for agricultural irrigation, spring floods would bring into existence much larger lakes. In Iran term ''Daryācheh-ye Sīstān'' (“Lake Sīstān”) is also used, with similar meanings, for lake Hāmūn-e Helmand.〔 ==Geography== It is located in Afghanistan which forms on the Sīstān marshes west of the Dasht-e Mārgow desert where the Helmand River forms a dendritic delta. Water flows in a circular fashion through a string of lakes starting with Hāmūn-e Puzak in the northeast, sweeping into Hāmūn-e Sabari and finally overflows into Hāmūn-e Helmand in the southwest. It used to cover an area of about 4,000 km2 (1,500 mi2) with dense reed beds and tamarisk thicket fringing on the edges of the upper lakes. Area was thriving with wildlife animals and migratory birds.〔 A trapezoid shaped basalt outcropping, known as Mount Khajeh,〔Mount Khajeh is named after an Islamic pilgrimage site on the hill: the tomb and shrine of Khwaja Ali Mahdi, descendant of Alī ibn Abī Ṭālib〕 rises up as an island in the middle of which used to be Hāmūn Lake and the northeastern edge of Hāmūn-e Helmand. Its flat-topped peak rises up 609 meters above sea level with a diameter 2-2.5 km, being the only remaining natural uplift in the Sīstān flatlands. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hamun Lake」の詳細全文を読む スポンサード リンク
