The Purari (also known as Puraari) is a river that originates in the south central highlands especially in Kandep District of Enga Province of Papua New Guinea, flowing Script error: No such module "convert".[1] though Gulf Province to the Gulf of Papua. The Purari has a Script error: No such module "convert".[2] drainage basin and is the third largest river in Papua New Guinea. The discharge varies through the year, averaging around Script error: No such module "convert".–Script error: No such module "convert". at the delta.
History
The headwaters of the river were charted in 1930 by Michael Leahy and Michael Dwyer.[3]
Geography
It is fed mainly by the Kaugel, Erave, Lai,[4] Tua and Pio rivers, starting just south of Mount Karimui at the junction of the Tua and Pio rivers, where it flows through a quite spectacular gorge before flowing out into the lowlands and delta country closer to the coast. River becomes tidal at substantial distance from the waters of Gulf of Papua. The Purari is a heavy muddy brown from silts washed down from the mountains, and rises and falls constantly depending on local rainfall.
Delta
The Purari Delta is one of a number of large deltaic complexes which border the Gulf of Papua. Along with the Fly, the Kikori and many other rivers, the Purari drains the western and central highland region of Papua New Guinea. Upper sections of these rivers are located in highly mountainous terrain reaching Script error: No such module "convert". at Mt. Wilhelm, with steeply descending valleys debouching onto a deltaic plain Script error: No such module "convert". wide. Average annual rainfalls ranging from Script error: No such module "convert". in the catchment of the Purari result in a mean annual discharge at delta of about Script error: No such module "convert"., carrying 88.6 million m3/year of sediment into the delta (Pickup 1980; this volume). These inputs provide the material for a major deltaic complex of global significance.

Biodiversity
The general area is heavy tropical jungle with high rainfall and abundant bird life.[5]
Economy
Along the river in various places there are small human populations, mostly subsistence villages. Dugout canoes are seen along the river from Wabo downstream, however population is sparse until you get closer to the coast where there are a few more villages.
Hydroelectric plant
The governments of Papua New Guinea and Government of Queensland have signed a Memorandum of Cooperation with PNG Energy Developments Ltd (PNG EDL) and Origin Energy (Origin) to support the potential development of a renewable hydro electricity project based on the Purari (Wabo Dam).[6]
