It is important to detect the occurrence of slope failure to reduce the damage by sediment disaster. Studies focusing on suspended solids concentration have been conducted to discover slope failure. There is a possibility that the suspended solids concentration may change due to the water accumulation of the Sabo dam. We observed in the downstream and upstream of the Sabo dam to investigate the influence on suspended matter concentration.
In result, the suspended matter concentration stays and settles in the water accumulation of the Sabo dam. We found that there is a possibility that the suspended matter concentration will be delayed or not transmitted downstream of the dam and it is necessary to observe with attention to fine particle sizes.
