Abstract

In this study, simulation technique with multi-dimensional model(EFDC), coupled with COSFIM and FLDWAV, has been applied to the upstream and downstream of weirs for hydraulic characteristics analysis through development of system and was performed for 8 multi-function weirs on Nakdong river using developed system. COSFIM, FLDWAV and EFDC can utilize suitable model in situation because they have pros and cons according to practical use purpose. Developed technique can offers spatial and grid unit information as well as line and section unit information from 1-D modeling. It is considered that the coupling simulation technique can provide useful hydraulic information for river management and treatment.

본 연구에서는 기존에 구축 운영 중인 COSFIM과 FLDWAV간 연계를 통해 다기능보 상 하류 구간 등 하천내 주요 관심구간에 대한 1차원 및 2차원 수리분석을 수행할 수 있는 시스템을 개발하고 낙동강 8개 다기능보를 대상으로 사업 전 후 수리특성 분석을 수행하였다. 각 수치모형은 활용목적에 따라 장 단점을 가지고 있기 때문에 상황에 적합한 모형을 선택적으로 활용할 수 있을 것이며, 기존의 1차원 수리 수문 모형으로 분석할 수 있었던 선 개념 지점 개념의 정보 뿐 아니라 추가적으로 공간 격자 개념의 정보를 제공받을 수 있는 다차원 모의를 수행함으로써 하천에서의 물리적 현상을 적절히 고려한 공간적 수리특성을 반영한 하천관리가 가능할 것이다.
