하안단구와 태백산지의 지반운동 유형 = River Terraces and Movement Type of Taebaek Mountain Range

다국어 초록 (Multilingual Abstract)

In Namhan and Nakdong drainage basin, river terraces are widely distributed. Height above riverbed of river terrace is the difference of altitude between the bed of past- and present-graded state in the fluvial system, and reflects the geomorphic processes which revive the stream`s downward erosive force and shape terrace landforms. Thus as analysing the relationship between height above riverbed of river terrace and the distance from the upwarping axis belt, I define the crustal movement type of Taebaek mountain range. ① Heights above riverbed of river terraces distributed in Namhan and Nakdong drainage basin increase upstream. ② High terraces in Nakdong drainage basin reflect the crustal movement type which uplift rate in the upwarping axis belt is comparatively greater than periphery. ③ The crustal movement type of Taebaek mountain range is that the range of 30㎞ around upwarping axis uplift rapidly and its periphery uplift slowly. ④ Low terraces seem to be not effected by upwarping of Taebaek mountain range.
