A long-range study on the hydrograph is necessary in estimating the pollution load from rivers during rainfall. During the heavy rainfall, such a load often corresponds to the total load at the ordinary flow level. The present study is made to determine the volume of suspended matter during rainfall in an indoor-scale circular waterway 2 m in diameter and centrally driven. The stepwise increase in shearing stress and migration of suspension from the river mouth sediment was already reported using this device. Further improvement is being made for an experiment under the condition close to heavy rainfall.
