The Mamberamo Lakes Plains (Dutch Meervlakte, Malay dataran danau-danau) [1] are a large, flat low-lying area of the Mamberamo River basin in the Indonesian province Papua on the island of New Guinea. The plain is defined by the meandering tributaries of the Mamberamo, and includes hundreds of oxbow lakes. It is 300 kilometers long and about 50 kilometers wide, and is entirely enclosed by mountains apart from the outlet of the Mameramo. [2] It is inhabited in the west, but the eastern lobe is largely uninhabited. [3]
Biologically, the plains are covered by tropical lowland jungle. Much of that is Adina and Barringtonia spicata (see Barringtonia ) swamp forest, large areas of sago palm, and marsh vegetation with Echinochloa stagnina . During the rainy season, large parts of the remaining forest is flooded for months at a time. These areas are populated with Timonius , Dillenia or Nauclea . [4]
South of the Lakes Plains lies the Central Dividing Range, the highest part of the western New Guinea Highlands, which drains into the basin. The basin is bisected by two major rivers, the Tariku, which originates in the Jayawijaya Mountains to the west and flows eastwards, and the Taritatu, which rises in the east, not far from the PNG border, and flows westwards. The major tributary of the Taritatu to the south, the Sobger River, originating in the Maoke Mountains, while to the north the Songgolo and Pauwasi Rivers join to form its other major tributary. In the middle of the Lakes Plains, the two rivers meet and merge to form the Mamberamo, one of the largest rivers of New Guinea. The Mamberamo flows out through a gorge between the Van Rees Mountains to its west and the Foja Mountains to its east. [2]

A distributary, or a distributary channel, is a stream that branches off and flows away from a main stream channel. Distributaries are a common feature of river deltas. The phenomenon is known as river bifurcation. The opposite of a distributary is a tributary, which flows towards and joins another stream. Distributaries are often found where a stream approaches a lake or an ocean. They can also occur inland, on alluvial fans, or where a tributary stream bifurcates as it nears its confluence with a larger stream. In some cases, a minor distributary can divert so much water from the main channel that it can later become the main route.
The Mamberamo is the second longest river on the island of New Guinea, after Sepik River. It is located in the Indonesian province of Papua. It is the largest river in Indonesia by volume of discharge, and also the widest.
Western New Guinea, also known as Papua, is the western portion of the island of New Guinea controlled by Indonesia since 1962. Since the island is alternatively named as Papua, the region is also called West Papua. Lying to the west of Papua New Guinea, it is the only Indonesian territory situated in Oceania. Considered to be a part of the Australian continent, the territory is mostly in the Southern Hemisphere and includes the Schouten and Raja Ampat archipelagoes. The region is predominantly covered with ancient rainforest where numerous traditional tribes live such as the Dani of the Baliem Valley although a large proportion of the population live in or near coastal areas with the largest city being Jayapura.
The Kapuas River is a river in the Indonesian part of Borneo island, at the geographic center of Maritime Southeast Asia. At 1,143 kilometers (710 mi) in length, it is the longest river of Indonesia and one of the world's longest island rivers. It originates in the Müller mountain range at the center of the island and flows west into the South China Sea creating an extended marshy delta. The delta is located west-southwest of Pontianak, the capital of the West Kalimantan province. This Kapuas River should be distinguished from another Kapuas River, which starts on the other side of the same mountain range in central Borneo, but flows to the south, merging with the Barito River and discharging into the Java Sea.

The topography of Pakistan is divided into eight geographic areas: the northern highlands, the Indus River plain, the desert areas, the Pothohar Plateau, Balochistan Plateau, Salt Range, and the Sistan Basin. All the rivers of Pakistan, i.e. Sindh, Ravi River, Chenab River, Jhelum River, and Sutlej River, originate from the Himalayas mountain range. Some geographers designate Plateau as to the west of the imaginary southwest line; and the Indus Plain lies to the east of that line.
