초록

본 연구는 국내 하천의 고유성을 반영할 수 있는 물리적 환경평가 체계를 개발하는 것이다. 하천유형 분류, 평가구간 선정, 평가 항목 및 지표에 대하여 종합적으로 요약하였다. 하천의 물리적 구조는 하천 유수력에 의한 반응의 결과이므로 하도경사, 하상재료의 입경 및 하도지형의 특성에 따라 하천을 3가지 유형으로 분류하였다. 평가구간은 각 하천 유형의 대표적인 특징인 step 또는 여울출현 간격, 사행도에 따라 저수로 폭의 10배와 25배 기준으로 선정하였다. 평가지표는 하도 안정성, 흐름 상태, 횡단면 형상, 하안 안정성, 하도개수 및 하천횡단구조물과 같은 공통지표와 유효 서식지, 하상 매몰도, 흐름의 다양성 및 step과 여울 출현빈도와 같은 하천 유형별 특성지표로 구성되어 있다. 적용성 검토를 위하여 개발된 평가체계를 9개의 하천에 적용하고 그 결과를 제시하였다.

This study is to develop an assessment system for stream physical environments by considering stream characteristics. Comprehensively, the descriptions of and steam classification, assessing reach selection, contents of assessment categories and indexes are summarized. Since the physical structure of stream is results of reaction by stream power, streams were classified into three types (as high gradient stream, mid gradient stream and low gradient stream) according to the slope of channel, the grain size of bed material and the characteristics of channel topography. The scale of assessment reach was selected based on 10 or 25 times of channel width according to typical characteristics such as interval of step or riffle and sinuosity in each stream type. The assessment indexes were organized into common indicators such as channel stability, flow status, cross-section shape, bank stability, channel alteration and stream crossing structure, and characteristic indicators by stream type such as effective habitats, bed embeddedness, diversity of flow and frequency of step or riffle. To evaluate the applicability, the assessment system was applied to 9 streams and the results were analyzed and presented.
