HydrologyThe river begins as the Baliem Timur (East Baliem) in the northern Maoke Mountains (Snow Mountains) at Lake Habbema in Jayawijaya Regency, north of Mount Trikora. The Baliem Timur flows west to meet the Baliem Barat (West Baliem) before turning north. After traveling underground for several kilometers through a sinkhole in an area of Karst limestone geology, it emerges and travels northeast to near Tiom in Lanny Jaya Regency. This section of the river was formerly known as the Noordelijke Baliem (North Baliem) in Dutch. After flowing east through Lanny Jaya, the Baliem turns southeast as it enters the wide, flat Great Baliem Valley. In the center of the valley it meanders southeast to meet the Uwe river in the city of Wamena. South of Wamena, the river plunges southeast through a steep gorge with many rapids and waterfalls, and is joined by the Mugi and Kwik rivers. 70 kilometers southeast of Wamena the Heluk river enters the Baliem near Holuwon village. From here, the river was called Vriendschaps River at the time of Dutch New Guinea, before the course of the river was fully explored.[2] Below Holuwon, the river leaves the southern foothills of the Maoke or Jayawijaya Mountains and becomes a braided river heading to the southwest through the lowland rainforest of southern New Guinea. After 100 kilometers, the Baliem, slightly upstream from the village of Kaima, flows into the Pulau River (formerly the Eilanden River), which flows into the Arafura Sea about 100 kilometers south-west on the Casuarina coast.[3]{{citation needed|date=October 2017}} EcologyBaliem River has a length about 60–80 km with the width of 15–20 m, flowing through the city of Wamena. The water temperature is around 14 to 18°C. The acidity of Baliem River around 6.8–7.5 and oxygen level is 4.1–4.3 mg/L. The flow rate is 0.09–0.92 m/det.; clarity 17–160 cm and depth 0.60–3.7 meter.[4] The acidity level of Baliem is considered good for the growth of water organism, such as fish. In Baliem also lives a kind of animal with high cultural value for the local people; valued as high as yam (hipiri) and pig (wam). It belongs to Cherax spp that lives in the mud. At night, it rises from the river and stays on the banks, whereas at sunrise, it goes back into deep river area. Along the banks there are swamps, with high tendecy of flooding and used by the community to let loose their pig herds. The river basin has high potential for tourism and agriculture.[4] GeographyThe river flows in the southern area of Papua with predominantly tropical rainforest climate (designated as Af in the Köppen-Geiger climate classification).[5] The annual average temperature in the area is 21 °C. The warmest month is March, when the average temperature is around 22 °C, and the coldest is July, at 18 °C.[6] The average annual rainfall is 6222 mm. The wettest month is May, with an average of 708 mm rainfall, and the driest is January, with 348 mm rainfall.[7] See also
