Rivers
Hai Phong has a dense network of rivers with an average density of 0.6 - 0.8 km of river per 1 km2. All rivers in Hai Phong are tributaries of Thai Binh River, which flows into the Gulf of Tonkin. Going upstream we can see the followings: Cau river rises from Van On mountainous area of Bac Can at the height of 1,179m, then runs down to Pha Lai to flow together with rivers of Thuong and Luc Nam to create Thai Binh river which flows down into plains for 97 km before flowing into the sea, where it changes its stream to direction of North West - South East.

Hai Phong has a dense network of rivers
with an average density of 0.6 - 0.8 km of river per 1 km2. All rivers in Hai
Phong are tributaries of Thai Binh River,
which flows into the Gulf
of Tonkin. Going upstream
we can see the followings: Cau river rises from Van On mountainous area of Bac
Can at the height of 1,179m, then runs down to Pha Lai to flow together with
rivers of Thuong and Luc Nam to create Thai Binh river which flows down into
plains for 97 km before flowing into the sea, where it changes its stream to
direction of North West - South East.
From place of their confluence, the rivers
flow on more and more descending slope and Thai Binh river creates a network of
tributaries of various levels such as rivers of Kinh Mon, Kinh Thay, Van Uc,
Lach Tray, Da Do... then flows into the sea through 5 major estuaries.
There are 16 major rivers which spread over
the entire territory of the city with the total length of more than 300km,
including:
- Thai Binh River of 35km long of which
main stream flows into the territory
of Hai Phong at Quy Cao
and then flows into the sea through Thai Binh estuary making a natural boundary
between Tien Lang and Vinh Bao rural districts.
- Lach
Tray River
of 45km long starts as a branch of Kinh
Thay River
at Kenh Dong and then flows into the sea through Lach
Tray River
mouth crossing the territory
of Kien An, An Hai rural
districts and the urban land of the city.
- Cam
River of 30 km is a branch of Kinh Mon River that crosses the urban area and flows into the
sea through the Cam river mouth. Hai Phong
Port has been developed
on the area of estuary of this river since the end of 19th century. The Cam River
is also the administrative boundary between Thuy Nguyen and An Hai rural
districts.
- Da Bach - Bach
Dang River
of 32 km is also a branch of Kinh Mon River flowing
into the sea through Nam Trieu estuary and it is also the boundary between the
North and North East part of Hai
Phong City
and Quang Ninh province. The estuary is wide and deep with magnificent
lime-stone mountain crags on the two sides. This place witnessed three glorious
feats of Vietnamese Nation in the history of wars against the northern invaders
in the 10th and 13th centuries.
- Besides the major rivers there are also
many other small and medium river branches which partition the terrain of the
city such as Gia River (in Thuy Nguyen district), Da Do River (in Kien An - Do
Son), Tam Bac River...
