Abstract
Currently, building a small dam located 1.16km downstream from Geumnam Bridge is being considered in order to improve the riverine scenery of the site for Sejong City and to create a hydrophilic space. The purpose of this research is to present the appropriate dimensions of a small dam by reviewing the flood control reliability of the Geum River after the small dam is built. To establish this purpose, changes in the flood water level were compared and analyzed by changing the installation height of a small dam using HEC-RAS and FESWMS models. HEC-RAS and FESWMS models were applied to perform the hydraulic analysis of the reach. The results showed that flood control reliability was guaranteed when the installation heights of the small dam were 7 meters and 5 meters using HEC-RAS and FESWMS models respectively. From the FESWMS model, a more accurate result can be developed because the model could provide a two dimensional hydraulic analysis. The results can be used to determine the appropriate dimensions of a small dam for Sejong City.
