Keelung River is a major river in Northern Taiwan that flows through Taipei and into Taipei Bay. It has played a central role in the urban development of Taipei and Keelung, influencing infrastructure projects such as the Taipei Basin flood defenses, Keelung Harbor access, and the Taipei Metro corridor. The river has been the focus of engineering works tied to events like the 1998 Taiwan floods and policies by the Ministry of Transportation and Communications (Taiwan).

Geography

The river rises near Sanzhi District in New Taipei and follows a sinuous course through the Taipei Basin, passing landmarks such as Yangmingshan National Park foothills, the Xindian River confluence area, and the Tamsui River watershed before reaching Keelung Harbor and Taipei Bay. It traverses administrative areas including Beitou District, Shilin District, Neihu District, Datong District, Zhongshan District, and Banqiao District, shaping urban neighborhoods like Dadaocheng and industrial zones near Wugu District. Tributaries and adjacent watersheds connect with systems around Taoyuan County and the Central Mountain Range foothills.

Hydrology

Flow regimes reflect seasonal patterns tied to the East Asian monsoon and episodic events such as typhoons—including Typhoon Herb (1996), Typhoon Nari (2001), and Typhoon Morakot (2009)—which have produced peak discharges. The river's discharge is monitored by agencies like the Water Resources Agency (Taiwan) and the Central Weather Administration, with gauging stations near Guandu and Bali. Sediment transport is influenced by upstream erosion in areas adjacent to Yangmingshan National Park and by urban runoff from districts such as Wanhua and Xinyi District, affecting turbidity at the estuary near Port of Keelung.

History

Indigenous peoples of northern Taiwan, including the Ketagalan, utilized the river corridor prior to contact with Spanish Formosa and Dutch Formosa colonial settlements. During the Qing dynasty, the waterway facilitated trade and migration into the Taipei Basin, later becoming strategic during the Sino-French War coastal operations and the Japanese rule in Taiwan modernization projects, which introduced canalization and embankment works. Post-World War II developments under the Republic of China (Taiwan) included industrial expansion, river straightening campaigns tied to urban planning by the Taipei City Government, and reconstruction after floods linked to typhoons like Typhoon Gloria (1963).

Ecology and Environment

Riparian habitats along the river host flora and fauna influenced by urban pressures; studies by institutions such as Academia Sinica, National Taiwan University, and Taiwan Environmental Protection Administration document biodiversity gradients. Bird species recorded near migratory stopovers include observers from groups like the Wild Bird Society of Taipei; fish populations have been affected by barriers and water quality, monitored by the Fisheries Agency (Taiwan). Pollution incidents prompted remediation programs coordinated with entities including Taipei Water Department, New Taipei City Government, and international partners in urban river restoration exemplified by projects comparable to those in Seoul and Tokyo.

Economy and Transport

Historically, the river corridor supported cargo movement to Keelung Harbor and local trade networks linking Dadaocheng Wharf with inland markets. Contemporary transport infrastructure parallels the river: corridors for the Taipei Metro lines near Zhonghe–Xinlu line, arterial roads such as the Zhongshan Expressway, and freight connections to Port of Keelung and the Taiwan Railways Administration lines. Riverfront redevelopment has spurred commercial zones with involvement from developers and planners tied to agencies like the Council for Economic Planning and Development (Taiwan), and recreational assets adjacent to parks managed by the Taipei City Department of Rapid Transit Systems and the New Taipei City Tourism Department.

Flood Control and River Management

Major flood control measures have included channelization, levee construction, and creation of detention basins coordinated by the Water Resources Agency (Taiwan), the Taipei City Government’s Public Works Department, and regional planning bodies. Notable projects responded to crises that affected urban infrastructure during events like Typhoon Soudelor (2015) and the 1998 Taiwan floods, prompting integrated basin management strategies drawing on expertise from National Taiwan University Hospital for emergency planning and from international partners experienced in the Netherlands Delta Works and Mississippi River management practices. Ongoing initiatives aim to balance flood risk reduction with ecological restoration through collaborations with NGOs such as the Taiwan Environmental Information Association and academic centers at National Taiwan Normal University.
