| Abstract;Countermeasures to decrease sediment accumulation in reservoirs are important to keep functions of reservoirs. Also in recent times an idea of unified management of sediments from mountains to the sea is increasingly promoted. On the other hand, more effective utilization of sediments for such as concrete aggregates has to be taken into account as natural resources have become scarcer. Here we report accumulation of sediments in the reservoir in Central Japan as an example, and discuss mechanism of sediment accumulation based on many drilling and grain size distribution data.
