Abstract
A network of channels which consists of the Ota River floodway and five branched rivers is formed in the Ota river delta. To estimate flood discharge hydrographs and bed variations in each channel is important for proper river management. Therefore, we developed a numerical model for the flood flow and bed variation analysis using time series of observed water surface profiles with the networked rivers in the Ota river delta. As a result, the unsteady quasi-three dimensional analysis of flood flows and two dimensional analysis of bed variations using time series of observed water surface profiles is found to provide good results for the flood discharge distributions in the networked rivers in the Ota river delta.
