| KEUM River downstream has some characteristics in which the dowunstream is affected with tidal motion, the several tributaries are forming a dendritic river system, and the channel cross-sections are irregular. The flood in this downstream can now be analyzed by the hydrological flood routing methods and under the assumption regarding the dendritic river system as a single reach. In this study the river system was used for the flood routing. The flood records which were measured in 1978 and 1987 were applied for calibration and verification of the unsteady flow model respectively. The results show that the flood at KANG-KYONG station was not affected with the tidal motion when the discharge at KONG-JU station exceeded about 5, 000$m^3$/sec, and that the bottle neck at IP-PO station intercepted the tidal influences. |
