The Taipei-Taoyuan area ranges in altitude from sea level along the west coast to over 2000 m in the southern tip of Taoyuan County. Taipei Basin, which is situated in the central part of the study area, is surrounded by hill slope areas. Tanshui River, the major stream network in northern Taipei, flows approximately 158.7 kilometers from its headwaters in Hsin-Chu County and passes through Taoyuan County, Taipei County and Taipei City before draining into the Taiwan Straits. Keelung River, Hsintien Creek and Tahan Creek, the major tributaries of Tanshui River, intersect in Taipei Basin and become the main branches of Tanshui River.
