AB - In this study, the stability of the Stream Control Frame constructed in a river to improve the environmental features of the watercourse was analyzed. The main functions of the Stream Control Frame are to induce a linear stream and to reduce the flow rate, thereby preventing the erosion of the river bank and hillside slopes and helping form small irrigation ponds that will serve as home to many aquatic organisms. To maintain these functions, the stability of the Stream Control Frame according to the changes in the flow rate of the river needs to be analyzed. As in the analysis through hydraulic-model experiments there is a limitation in determining the results of cases with various time and cost conditions, one- or two-dimensional numerical simulation is currently being applied. In this study, to apply two-dimensional numerical simulation, the simulation discharge was calculated using the rainfall-runoff models SSARR and HEC-HMS, and the elevation was estimated using HEC-RAS, a one-dimensional numerical analysis model. Hydraulic analysis was carried out using the RMA-2 model, to simulate the two-dimensional flow shapes before and after the construction of the Stream Control Frame under the conditions of maximum flood(775.1㎥/s) and normal stream flow(6.18㎥/s). From the analysis of the flow rate distribution around the Stream Control Frame, the simulated maximum flow rates before and after the construction of the Stream Control Frame were found to be 4.11 and 3.65m/s in the case of the maximum flood, and 0.24 and 0m/s in the case of the normal stream flow. Considering that the acceptable-limit flow rate of the Stream Control Frame constructed within the analysis section is 4.0m/s, the Stream Control Frame is judged to be quite stable because the maximum flow rate after the construction of the Stream Control Frame turned out to be 3.65m/s. The analysis data on the physical characteristics obtained via hydraulic/hydrological analysis of Stream Control Frame is expected to be utilized for making basic materials required for the operation of the Stream Control Frame that will be constructed in the future.
