抄録

Present paper illustrates briefly several issues for flood disaster mitigations and environmental resources in rivers, focusing on sediment transportation and associated topographic changes caused by debris flows in steep areas as well as by bed loads and suspended loads in alluvial reaches. In addition, several methods and correspondingly predicted results are shown for evaluating these sediment problems. Finally, the author will review the mechanics employed in existing methods in order to suggest what a stiff wall is there and to show a possibility for a new start. However, it may be conceited.
