Step-by-step explanation:
The Ok Tedi River is located in the western region of Papua New Guinea. It flows through the Star Mountains and the remote and rugged terrain of the Western Province. The river is a significant waterway in the country, running for approximately 1,000 kilometers before merging with the Fly River near the town of Kiunga.
The Ok Tedi River in Papua New Guinea is a significant waterway that flows through the western region of the country. It originates from Mount Fubilan in the Star Mountains and runs for approximately 1,000 kilometers before merging with the Fly River. The river traverses remote and rugged terrain, passing through dense rainforests and mountainous landscapes.
Geographically, the Ok Tedi River originates from the slopes of Mount Fubilan in the Star Mountains, located in the central part of the province. It flows in a generally westward direction, cutting through deep valleys and gorges. The river passes through a mix of dense tropical rainforests, mountainous landscapes, and eventually reaches the floodplain areas near its confluence with the Fly River.
The biophysical characteristics of the Ok Tedi River and its surrounding area are influenced by the local geology, climate, and vegetation. The region experiences high rainfall, especially during the wet season, which results in significant water flow in the river. The river's water is fed by numerous tributaries originating from the Star Mountains.
One of the major factors that have impacted the Ok Tedi River and its ecosystem is mining activity in the region. The Ok Tedi copper and gold mine, operated by Ok Tedi Mining Limited, has been a source of environmental concern due to its impact on the river system. Discharges of mine tailings, containing copper, sediment, and other contaminants, have caused significant pollution and ecosystem degradation in the river.
Numerous scientific studies and reports have documented the environmental impact of mining on the Ok Tedi River. The most notable among them is the Ok Tedi Environmental Impact Study, commissioned by the Papua New Guinea government and undertaken by international consultants, which extensively documented the adverse effects of mine waste discharge on the river ecosystem.
