Isotopic and Elemental Hydrogeochemistry of the Han River, South Korea

摘要

The Han River is the largest river in South Korea and supports a variety of industrial, agricultural and human activities, including water supply for a metropolitan city, Seoul. It consists of two major rivers (the North and South Han Rivers) and many tributaries. The river originates at altitudes of more than 1,300 meters above sea level in the Taeback Mountains, which run subparallel to the eastern coast of South Korea, and traverse the mid-western parts of the Korean peninsula before flowing into the Yellow Sea. The North Han River drains a basin consisting of the Precambrian gneissic basements and Mesozoic granites, whereas the South Han River drains a basin consisting of the Paleozoic sedimentary rocks (mostly carbonates) and Mesozoic granites
