In Japan, many of the recent sabo dam constructions have been of the open-type in consideration of the continuity of sediment routing from upstream to downstream reach in a river basin. A lot of experimental and numerical research has been conducted on sediment control using concrete slit dam, slit dam with steel grids and so on. However, there are a few researches which discuss sediment runoff and its control near upper parts of the grids, while channel shifting and bars movements can be active due to deposition after huge volume of sediment is captured in the storage area of sabo dam<br>In the present study, the sediment control function of the “grid-type sabo high dam (GHD)”, which is defined as a gridtype sabo dam with a height over 15 m, was examined preliminarily using experimental data sets such as dimensionless sediment runoff volume passing through the check dam. Flume experiments for sediment control using a kind of “steel wire-nets” near the vertically upper parts of the grid were conducted focusing on the simple and the effective countermeasures for the sediment storage in a sabo dam, and sediment control in present easy way, in which steel wire nets could be flexible and removable, was confirmed.
