The target area is the Lower Mekong River Basin, which suffered from severe floods in 2000 and 2011. First, measurement using an acoustic Doppler current profiler is conducted to understand the longitudinal distribution of cross sectional shapes and roughness change during a flood in a river channel. Based on the observation results, inundation simulation with the Rainfall-Runoff-Inundation model is conducted. The calculation results show that the reproducibility of discharge improves by taking the longitudinal distribution of the width and depth of the river reach into consideration, and that the water depth over the floodplain has a high sensitivity to both cross sectional shapes and roughness change during the flood.}, pages = {145--150}, title = {メコン川下流域の洪水氾濫に対する観測結果を反映した河道条件の影響分析}, volume = {72}, year = {2016}, yomi = {クドウ, シュン and ヨロズヤ, アツヒロ and コセキ, ヒロシ and イワミ, ヨウイチ and ナカツガワ, マコト} }
