Abstract

River areas include channels, floodplains and all the areas affected by physical and ecological processes in river systems. It is noticeably different from present riparian zone which is bounded by dykes. In this study, two methods for delineation of a floodplain are proposed, which are used for evaluation of the function of a river. One of them is a geomorphology-based technique and the other is hydrology-based inundation analysis. For the Mankyung River, these two methods are applied to delineate the floodplain area. Areas delineated with both methods are mutually compared. The results show that the geomorphology-based method is suitable for the delineation of a valley bottom, including the floodplain in a broader sense, which is unlike an inundated area reflecting contemporary hydrologic conditions. Compared with other flood frequency areas, a 100-year flood inundation area was found reasonable to represent the spatial extent of a floodplain without regard to the longitudinal location along a river. However, it is necessary in certain rivers reach where the division of a channel exists to compare a geomorphological analysis on a valley bottom with an inundation area of different frequencies.

하천공간이란 하천시스템과 관련된 물리적·생태적 프로세스에 영향을 받는 홍수터, 하도를 모두 포함하는 공간을 의미하므로, 제방에 의해 인위적으로 차단된 현재의 하천구역과는 분명히 구분된다. 본 연구에서는 하천기능 평가를 위한 공간경계를 결정하기 위하여 홍수터 공간을 획정하는 방안을 제시하고자 한다. 이를 위하여, 지형분석 방법과 범람분석 방법을 이용하였고, 각 방법으로 산정된 만경강 홍수터 공간을 비교, 검토하였다. 분석결과, 지형분석은 곡저의 추출에 적합하며 현재의 수문지형조건을 반영하는 범람공간과는 차이가 있음을 확인하였다. 또한 빈도별 범람면적을 비교함으로써, 하천 상류 혹은 하류 구간의 구분 없이, 100년 빈도 범람지역을 하천공간으로 획정하는 것이 타당할 것으로 판단되었다. 그러나, 하도의 분기가 발생되는 일부 구간에서는 지형학적 곡저 분석 결과와 다양한 빈도의 범람해석 결과와의 비교가 필요하다.
