Sungari River

Sungari River
Chinese Songhua Jiang or Sung-hua Chiang

River, northeastern China.

Rising in the Changbai Mountains, it is joined by its chief tributary, the Nen River, before it enters the Amur River 1,197 mi (1,927 km) later. The Amur's largest tributary, it passes through a fertile plain and is navigable for much of its course.

Chinese (Pinyin)  Songhua Jiang  or  (Wade-Giles romanization)  Sung-hua Chiang 
 river in Heilongjiang (Heilungkiang) and Jilin (Kirin) provinces, northeastern China. The Sungari is the largest of the tributaries of the Amur River, which it joins below the Chinese town of Tongjiang, some distance above Khabarovsk in far eastern Russia. The total length of the Sungari is 1,195 miles (1,925 km), some 800 miles (1,300 km) of which traverse the Northeast (Manchurian) Plain (Northeast Plain). Its drainage area is about 212,000 square miles (550,000 square km).

      The Sungari rises in the Changbai Mountains in the border area between Jilin and North Korea (Korea, North). Its upper course runs north through rugged country, after which it flows out onto the Northeast Plain above the city of Jilin (Kirin). There the river has been dammed at Fengman (Fengman Dam) as part of a huge hydroelectric project, forming a large retention lake more than 125 miles (200 km) long. From Jilin the river flows northwest until, in the vicinity of Da'an, it is joined by its chief tributary, the Nen River, which drains the northern Northeast Plain. It then flows eastward through the city of Harbin, where it is joined by another northern tributary, the Hulan River, before passing between the southern end of the Xiao Hinggan Range and the northern extremity of the Changbai Mountains at Jiamusi to emerge into the flat and marshy terrain of the Amur River valley.

      The Sungari below Jilin generally flows more placidly than it does farther upstream. Seasonal variations in its flow, however, can be considerable. The river, frozen annually from late November until March, reaches its maximum flow in the summer. As a result of thawing mountain snows from May and summer rains that last until August, together with a low river gradient in the plain, flooding is frequent. In some years, floods have caused great devastation.

      The Sungari, like the Nen, is an important waterway. It is navigable upstream as far as Harbin by steamships of up to 1,000 tons. Small river steamers can use the Sungari as far as Jilin and the Nen as far as Qiqihar, while several of the other tributaries and the upper waters of the Sungari and the Nen are navigable by small craft.
