FLUMEN 모형에 의한 군장지구 단지 개발에 따른 홍수범람 분석

군장지구 개발에 따른 홍수 범람을 분석했다.

This study minimizes life damage, social and economic damage of the area conferring flood inundation because of changing a application condition of a hydraulic structure, also provides basic data to make a fitting application environment of a hydraulic structure. It makes available preparation before a thing takes place about the disaster which will be possible in the future executing a flooding analysis about the area progressing development and each scenario's zone using the 2 dimensional model FLUMEN to be made a fitting development project.

FLUMEN model developed by Beffa(1999), using Shallow Water Equation basically, can apply to grid and irregulated triangular and is a common model which can apply to hydraulic analysis complicated like a joining or a bending area. In this study, two dimensional model has been applied for the topographic features around Soli stream and Wolpo stream in Janghang, the meandering and the curvature of a river bed, and so on, considering the uncertainty of the coefficient that can apply to the unidimensional model and the processing of the moving boundary, the flow direction and the travel time in case that the flood is propagated to the flooded Area.

And NGIS data of the NGI(National Geographic Information Institute), design data of the Basic Plan for the River Development and Management of a local autonomous entity has been used for the processing of the topographic data. In the treatment of the unsteady flow, flood Hydrograph calculated through the hydrological analysis with boundary conditions in the entrance of the upriver. In the result of the study, the most effective proposal for the effect of the flood in the flooded area and instream was identified as a gate design condition for the rivers by the results of simulations for the flood of Soli stream and Wolpo stream.
