Parnaíba
a river in northeastern Brazil. It is about 1,450 km or, according to other sources, 1,700 km long. It drains an area of about 350,000 sq km. It rises in the Brazilian Highlands, on the slopes of the Serra de Tabatinga. There are rapids in the upper and middle course. The lower course crosses the Parnaíba depression, where the river becomes navigable at the city of Teresina. The river regularly floods. The average annual flow of water is about 2,400 cu m per sec. The Boa Esperança hydroengineering complex (a complex consisting of power plants, reservoirs, canals, and the like) has been under construction since 1964. In 1970 the first phase of a hydroelectric power station with a 164-megawatt capacity was completed. The cities of Floriano, Teresina, and Parnaíba are situated on the Parnaíba.
