Tamsui River Basin (Taiwan)
The Tamsui River (淡水河 in Chinese), located in Northern Taiwan, is one of the largest river of the country. The river basin has a drainage area of 2.726 km2 and it drains Taipei city with a population of 6.5 million. The river has three tributaries: Xindian Creek, Dahan Creek and Keelung River where are located Feitsui Reservoir and Shimen Reservoir (are the major sources of water in Taiwan).
Taiwan is one of the most typhoon-impacted regions in the world. It´s hit every year by 3-4 typhoons (according to the Central Weather Bureau). Those extreme weather situations, torrential and sustained rainfall, characterize the hydrological behavior of the basin.
