Great Man-Made River
The Great Man-Made River (GMMR, النهر الصناعي العظيم) is a network of pipes that supplies fresh water obtained from the Nubian Sandstone Aquifer System fossil aquifer across Libya. It is the world's largest irrigation project. The project utilizes a pipeline system that pumps water from the Nubian Sandstone Aquifer System from down south in Libya to cities in the populous Libyan northern Mediterranean coast including Tripoli and Benghazi. The water covers a distance of up to 1,600 kilometers and provides 70% of all freshwater used in Libya.
According to its website, it is the largest underground network of pipes (2,820 kilometres (1,750 mi)) and aqueducts in the world. It consists of more than 1,300 wells, most more than 500 m deep, and supplies 6,500,000 m3 of fresh water per day to the cities of Tripoli, Benghazi, Sirte and elsewhere. The late Libyan Leader Muammar Gaddafi described it as the "Eighth Wonder of the World".

River Ranking by Water Flow Rate
This article lists rivers by their average discharge measured in descending order of their water flow rate. Here, only those rivers whose discharge is more than 2,000 m3/s (71,000 cu ft/s) are shown, as this list does not include rivers with a water flow rate of less than 2,000 m3/s (71,000 cu ft/s). It can be thought of as a list of the biggest rivers on earth, measured by a specific metric.
For context, the volume of an Olympic-size swimming pool is 2,500 m3. The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The average flow of all the rivers in this list adds up to 1,192,134 m3/s.
