Sediment bypass tunnel is under construction for reservoir sedimentation management in Koshibu dam.
After completion of the tunnel, fine and coarse sediment will be released by bypass operation which willbe transported in the downstream river channel. In order to investigate future sediment transport capacity
after the bypass completion, we experimentally examined present sediment transport condition with RFID(Radio Frequency Identification Device) by installing IC-Tag in several gravels placed below the dam.
Since detection rates of IC-Tag were very high where the maximum transport length was up to more than
1000m, RFID will be useful to track gravel movements. Critical shear stress calculated by 2D numericalmodel shows well agreement with actual movements based on placed conditions and grain seizes.
