초록

하천의 흐름 특성과 더불어 하상 변동을 연계하여 분석하는 일은 하천관리에 있어 가장 기본적이면서도 중요하다. 상류에 건설되는 신규댐 등 다양한 목적의 수공구조물이 계획될 때 하류 하천의 하상변화에 미치는 영향은 향후 하천을 지속적이고 안정적으로 보존, 관리하는데 반드시 고려해야 할 사항이다. 본 연구에서는 내성천을 적용 대상으로 항공사진 등을 활용한 하천의 장기적인 지형변화 양상을 고찰하였다. 아울러 1차원 수치모형인 GSTARS를 적용하여 주요지점의 하상변동 영향을 분석하였다. 장기적인 지형변화 양상을 바탕으로 댐이 건설된 후 내성천의 관리방안을 모색해 볼 수 있을 것이다.

Trying to estimate variations of the riverbed is basic and important for river management. When new dam constructed in upstream and a structure were planned, impact of the riverbed changes in downstream should be considered for stably maintained and sustained rivers in the future. In this study, long-term riverbed changes analyzed using aerial photographs in Naeseongcheon. Also applying one-dimensional numerical model, GSTARS analyzed the effects of bed deformation in critical points. Based on Changing Patterns of long-term riverbed, it is possible that after the dam was built, to explore how to manage Naeseongcheon.
