The Nabataeans created this artificial oasis by controlling, capturing and cleverly using the water from the flash floods. Huge cisterns were used for storing it during the dry months and an ingenious system using the natural terrain features and the simple rule of gravity allowed for its general distribution. They also harnessed all the caravan trade that passed through the area and thus became exceedingly rich.
