  • Stream piracy is one of the dynamic geomorphic processes in the mountainous area. If many stream piracies were concentrated in a certain region, the concentrated distribution of those might reflects the geological structure and tectonic movements of that region. In this study, the stream piracies identified in the lower areas between the Chiri and the Deokyoo mountainous areas were analyzed in relation with the tectonic line from Kwangju to Pohang and the so-called Hansan Mountains. The stream piracy at the Subunchi occurred between the lower-altitude, higher-gradient upper reach of the Seomjin-River flowing on the lower-level basin and the higher-altitude, lower-gradient upper reach of the Geum-River flowing on the higher-level basin. The geomorphic evidences concerning the stream piracy and the human responses to the headward erosion might be found in the vicinity of stream piracy site. Together with the Deunbongsaem(the source fountain of Geum-River), the Subunchi at which the geomorphic processes of stream piracy could be identified in a small area will be a good site for the geography education as well as the geo-tourism.
