Research overview:
As the relation of changes in topography and components of river channel during flood with creation and transition of plant community became clear, it has been recognized that changes in topography and components of river channel might be a main factor for degeneration of whole river ecosystem. This investigation aims to identify changes in topography of river channel and underground components as direct causes for degeneration and to clarify the process of degeneration and to propose preserving procedure for ecosystem (the model for prediction of river channel topography and underground) and basic concept (management of the earth and sand on basin-scale and a new river channel plan).
