Abstract: Sandbars make meandering of flow and cause the local scouring and deposition on riverbeds. The sandbars formed on riverbeds are closely related to river disasters. It is very important subject on river management works to understand the bed variation caused by the sandbars. The flood by the local heavy rainfall, which is increasing in recent years, has a large variation of water level with time. In order to understand the behavior of sandbars during flood, it is necessary to take the unsteadiness of flow into consideration.
