the word dam can be traced back to Middle English‚[1] and before that‚ from Middle Dutch‚ as seen in the names of many old cities.[2] Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level‚ for Mesopotamia’s weather affected the Tigris and Euphrates rivers‚ and could be quite unpredictable. The earliest known dam is the Jawa Dam in Jordan‚ 100 kilometres (62 mi) northeast of the capital Amman. This gravity dam featured an originally 9 m (30 ft)
