Drainage patterns were investigated to interpret the unknown geologic structure and geomorphic history in South Korea. Dendritic and rectangular patterns are most prominent ones developed in the granitic and sedimentary terrain. Drainage density ranges from 0.47 in the Nakdong river basin to 0.31 in the South Han river basin. Fine drainge texture is appeared in the Nakdong basin characterized by sedimentary beds of Mesozoic age, and coarse one are in the South Han river basin where Precambrian metamorphic rocks are dominated. Geological structures interpreted by stream pattern analysis are reasonally good agreement with the result by lineaments analysis and geological mapping.
