Abstract

Two-dimensional numerical simulations of flood flow in the Oono and the Ototu River with and without vegetations were performed to examine flood control function of vegetation. A two-dimensional numerical model, based on finite-volume method with unstructured grid system and flux-difference splitting was used for the simulations. From the numerical results, useful information to manage the vegetation, such as specification vegetation which has possibility of causing a high-speed velocity along the embankment, a big influence on the water level rise, the protection function of the embankment and the riverside, was obtained. It shows that the two-dimensional numerical simulations are useful tool to examine the management of the vegetationinthe Oono and Ototsu River.
