Ussuri

(o͞oso͞o`rē), Mandarin Wusuli, river, c.365 mi (590 km) long, formed by the confluence of the Ulukhe and Daubikhe rivers, S Maritime Territory, Russian Far East. It flows N to the Amur River at Khabarovsk, forming part of the Russia-China border. The Ussuri abounds in fish, and it is used to transport timber. The Ussuri-Khanka lowland is a fertile agricultural region. Armed border clashes between Soviet and Chinese forces occurred (1969 and 1972) along the river, leading to a military buildup. In 1991 in a peace gesture, the USSR announced the transfer of some of the islands in the river to Chinese control. The border was finally settled by Sino-Russian agreements in 2004 and 2008, which involved additional territorial transfers.

Ussuri

 

a river in Primor’e Krai, RSFSR, that also flows along the border of Primor’e Krai and Khabarovsk Krai, RSFSR, with China; a right tributary of the Amur River. The Ussuri measures 897 km in length and drains an area of 193,000 sq km. It originates in the mountains of Sikhota-Alin’. For most of its course it is a plains river; only in its middle course do spurs of the mountains approach the plain, forming rocky, precipitous banks. There are twists and branches in many sections of the Ussuri, as well as groups of islands. The river empties into the Kazakevichevo, a branch of the Amur.

The Ussuri relies on rain for as much as 60 percent of its water; snow accounts for as much as 30–35 percent in winters with heavy snowfalls, and subterranean waters account for the rest. High water lasts from late March to August, beginning with melting snows and rains and continuing with flash floods.

The mean flow rate is 143 cu m per sec in the upper course, 230 cu m per sec in the middle course, and 1,150 cu m per sec in the lower course (147 km from the mouth). The maximum flow rate is 10,300 cu m per sec in the middle course and 10,520 cu m per sec in the lower course. Catastrophic floods are frequent. The river freezes in November, and the ice breaks up in April. The principal tributary is the Arsen’evka, on the left.

The Ussuri abounds in fish, mainly grayling, kaluga, and sturgeon. Pink salmon and dog salmon spawn in the river. In the upper course, as far as Lesozavodsk, the river is used for floating timber. The river is navigated, although not regularly, 622 km from the mouth. It is also used as a source of fresh water.
