| Research Abstract |
The channel shift with bank erosion at the time of the actual flood in 2010 and 2011 was analyzed using the theoretical analysis and newly developed numerical computation model which can calculate bed deformation and bank erosion. The quantitative evaluation of the relation between bar formation, the channel which is formed on bars and the disaster was carried out. And the formation process of the new channel with bank erosion was examined. Moreover, the continuation mechanism of bed forms was elucidated using the numerical model for bed deformation with new boundary fitting method based on the Cartesian coordinate system.
