The Amur River, also known as the Heilongjiang River, rises in Russia
east of Lake Baikal as the Shika River flows into the Argun River. The
tenth-longest river in the world, the Amur flows about 1,800 mi (2,897
km) from this confluence (or 2,761 miles/4,440 km if the Argun is
included) and has a drainage basin of roughly 1,855,000 square km
(716,220 square miles). As the Amur curves to the east and then
southeast, it forms the border between China’s Heilongjiang province
and southeastern Siberia, Russia.
The Amur River’s water levels change dramatically throughout the year.
Heavy summer (monsoon) rains typically pour down in July and August,
causing flooding along the river. Sometimes rapid ice and snow melt in
the springtime can cause floods as early as late April or May. In 2021,
reports of flooding along the Amur River began to emerge in mid-May as
a combination of rain and snow melt filled the riverbanks to
overflowing, particularly in Khabarovsk Krai in eastern Russia.
According to news reports, as of June 7 flooding continued along the
Amur River, with the crest approaching the city of Komsomolsk-on-Amur,
which is located on the river in Khabarovsk Krai.
On June 8, 2021, the Moderate Resolution Imaging Spectroradiometer
(MODIS) on board NASA’s Aqua satellite acquired a true-color image of
the Amur River separating Russia (north) from China (south). The
swollen rivers of the region are easily visualized, including the large
The land of Heilongjiang province, sitting south of the Amur River, is
colored in the tans and light greens of active agricultural land, in
contrast to most of Russia which is swathed in rich greens of forest
and grasslands. Cement-colored spots dot the landscape in Heilongjiang,
each marking a city or town while fewer cities are seen in Russia. A
large area of tans and grays where The Amur meets the Ussuri River
marks the city of Khabarovsk, the administrative center of Khabarovsk
Krai. It sits only 19 miles (30 km) from the China-Russia border.
