The Ussuri or Wusuli (Russian: Уссури;) is a river that runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border (which is based on the Sino-Russian Convention of Peking of 1860), until it joins the Amur as a tributary to it near Khabarovsk. It is approximately 897km (557miles) long. The Ussuri drains the Ussuri basin, which covers 193000km2.[3] Its waters come from rain (60%), snow (30 - 35%), and subterranean springs. The average discharge is 1620m3/s,[4] and the average elevation is 1682m (5,518feet).
The Ussuri has been known by many names. In Manchu, it was called the Usuri Ula or Dobi Bira (River of Foxes) and in Mongolian the Üssüri Müren. Ussuri is Manchu for soot-black river.[5]
Major tributaries of the Ussuri are, from source to mouth:
