The Taipei Basin ( traditional Chinese : 臺北盆地 ; simplified Chinese : 台北盆地 ; pinyin : Táiběi Péndì ) is a geographic region in northern Taiwan . It is the largest basin in Taiwan. The basin is bounded by the Yangmingshan to the north, the Linkou Plateau to the west, and the Ridge of Xueshan Range to the southeast. The shape of the basin is close to a triangle. The three vertices are Nangang , Huilong of Xinzhuang , and Guandu of Beitou .
11-727: The main rivers in the Taipei Basin include the Tamsui , Keelung , Dahan and Xindian . In the prehistoric era, the Taipei Basin was home to Ketagalan tribes. Han Chinese did not settle in the region until the 18th century. Today, Taipei Basin is within the boundaries of Taipei City and New Taipei City and is the largest metropolitan area in Taiwan . The Taipei Basin is a subsiding half-graben . The Taipei Basin rivers are heavily polluted by both raw sewage and industrial pollution from illegal industry. The natural river restoration
22-592: A number of closely related species, making identification and reports of distribution quite confusing. Less precise sources may describe a large range in East Asia, in waters tropic to temperate. However, as Hsiao & Chuang (2023) demonstrated using molecular (nuclear + mtDNA) and multi-variate morphological means, it is possible to distinguish several species: There is one report in 2022 of M. lusoria appearing in Sarawak ( Malaysian Borneo ). The identification
33-604: A total length of 159 km (99 mi) and a drainage area of 2,726 km (1,053 sq mi). A major artificial distributary on the left bank of the Tamsui, the Erchong Floodway , was completed in 1984 as part of a flood control scheme for the Taipei Basin . The flood control plan for Greater Taipei dated back to 1959, and by 1987, dykes had been built along the banks of the Tamsui. The Tamsui River
44-464: Is a species of saltwater clam, a marine bivalve mollusk in the family Veneridae , the Venus clams. This species is native to Asia, originally described around the waters of Japan . It is commercially exploited for sushi , and its shells are traditionally used to make white go stones. The hamaguri clam is the subject of a haiku by Matsuo Bashō . Meretrix lusoria is morphologically similar to
55-491: Is heavily polluted by both raw sewage and industrial pollution from illegal industry. Clean up and natural river restoration is on the agenda of the Taipei City Government , Executive Yuan and several citizen organizations. Through the 1970s, the river was clean and could support ship traffic and fishing. By the 1980s, the Tamsui was polluted and was dominated by tilapia. Governmental efforts to clean up

It is located in northern part of the island. The Tamsui River begins at the confluence of Xindian River and Dahan River at the western boundary of Taipei and New Taipei City, just north of Banqiao District , and flows northward and northwestward, passing
88-789: The eponymous Tamsui District , then emptying into the Taiwan Strait . The river's three tributaries are the Xindian River , Dahan River and Keelung River . The Dahan River is the main tributary and has its headwaters in the Pintian Mountain in Hsinchu County and flows through Hsinchu County , Taoyuan City and New Taipei City . As a river system including the Dahan River, the Tamsui River has
99-679: The Tamsui include "The Recovery Project of the Tamsui River Watershed Area" implemented in 1987 by the Environmental Protection Administration , at the time a division of the Department of Health . This effort was finally undertaken as a result of massive public pressure. The first goal set was to have the river no longer smell in the summer. Water quality improved significantly however efforts to improve water quality were hampered by
110-418: The numerous residences whose sewage emptied straight into the river. Cleanup efforts continue to the present day, and include linking the watershed's residents to a shared sewer system. Scientists conducting research on what they believed to be Meretrix lusoria in the Tamsui River sent samples for genetic analysis and discovered that they were a distinct species: Meretrix taiwanica . Due to its pollution
121-453: The phrase “I’d rather jump into the Tamsui River!” was once a popular saying in Taipei. Several famous bridges run across the river, from south to north downstream: 25°10′30″N 121°24′30″E / 25.175°N 121.408333333°E / 25.175; 121.408333333 Meretrix lusoria Meretrix lusoria , the hamaguri , Asian hard clam or common Orient clam ,
