抄録

Although extensive research works have been performed on hydrodynamics of vegetated channels, little attention was paid on flow resistance mechanisms being dependent on submerged-level of tree vegetations. The authors developed a 2-D two-layer model that can simulate flows not only through but also over the vegetation, which enables us to analyze all ranges of water level and vegetation height. A H-ADCP system was equipped in a river to measure a time-dependent velocity profile in span-wise direction. The H-ADCP data and information on tree destruction were collected from several flood events during 2009-2010, which were compared with the analytical solutions. The numerical solution was in good agreement with the observed flow fields and the destructed tree areas, respectively. The findings are to contribute to devise a proper and feasible river management strategy.
