The Lake Homs Dam is a Roman-built dam near the city of Homs, Syria, which is in use to this day. Contrary to an older hypothesis which tentatively linked the origins of the dam to Egyptian ruler Sethi (1319–1304 BC), the structure dates to 284 AD when it was built by the Roman emperor Diocletian (284–305 AD) for irrigation purposes.〔; 〕 With a capacity of 90 million m³, it is considered the largest Roman reservoir in the Near East〔; 〕 and may have even been the largest artificial reservoir constructed up to that time. Remarkably, the reservoir has suffered very little silting since.〔; 〕 The 2 km long and 7 m high masonry gravity dam consists of a Roman concrete core protected by basalt blocks. The slightly pointed curvature of the dam follows the course of a long ridge of basalt and thus bears only superficial resemblance to an arch dam.〔 In 1938, the level of the dam was raised, increasing the volume of the artificial lake to 200 million m³.〔; 〕 __NOTOC__ == See also == *Al-Rastan Dam – located downstream *List of Roman dams and reservoirs *Roman architecture *Roman engineering 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「Lake Homs Dam」の詳細全文を読む スポンサード リンク
