内容記述 |
In the Muka River of the Tokoro River system, riverbed scouring has been progressing, influenced by reduction in the river width as a result of river channel improvements, reduction in sediment supply from the upper reaches and increases in discharge in recent years. As the result of riverbed scouring, soft rock and volcanic ash layers have been exposed. The progressive riverbed scouring has caused the banks to lose their ability to protect against flooding and has caused the bridge piers to have inadequate embedment depth. These have resulted in a loss of flood safety. To explore effective measures against riverbed scouring, the characteristics of river bed scouring were investigated. To retard the presently progressing riverbed degradation and to plan for a fundamental countermeasure, field trial was done in which the low-water channel was widened and the exposed soft rock was covered by gravel. This paper reports the results of investigation and field trial, and examines the efficacy of such construction. |
