Abstract

Recently, various new devices have been introduced, which are capable of quickly measuring river hydrodynamic and morphologic features in the very broad riverine area. These devices are changing paradigm of understanding river characteristics in terms of data-driven aspect rather than the conventional numerical modeling approaches based on the limited field observations. This paper demonstrates the representative features and applications of the several recent riverine devices such as ADCP, LSPIV, MBES and ABL. In addition, the paper introduces an example of river information system that incorporates and relates such two- and three-dimensional hydrodynamic and morphologic data on top of geographic information system, where their spatio-temporal variations are also able to be tracked.

최근 하천의 유동 및 하상 자료를 광범위한 영역에서 신속하게 계측할 수 있는 전자기파 기반의 수리계측기기들이 등장하여 하천의 특성을 이해하는 방식을 전통적인 수치모델링을 통한 방식으로부터 자료만을 활용하는 방식으로 전환되고 있다. 본 논문은 최신 관측기기로 초음파유속계(ADCP), 이미지 유속계(LSPIV), 복수빔 음파수심계(MBES), 공중 전파수심계(ABL) 의 관측 방식과 적용 사례를 보여준다. 그리고 관측된 2차원 혹은 3차원의 유동 및 하상 자료를 GIS에 기반하여 상호 연계하고 저장하여 하천의 시공간적인 변화를 추적할 수 있게 하는 하천정보화시스템의 구축방안을 제시한다.
