AB - Due to recent climate change, the frequency of heavy rainfalls and sediment disasters is increasing. In order to prevent damages caused by sediment disaster and implement a comprehensive sediment control, a time-series analysis of sediment discharge data is essential. However, in South Korea, it is difficult to measure them directly as they use conventional meters as measurement, which prevents research from presenting a quantitative relationship between hydrological factors and mechanisms with regard to sediment transport. In this regard, the study attempted to overcome difficulties related to the measurement of soil particle transport in river channel. It used acoustic signals to recognize the transport of sediment particles and established an indoor waterway experiment equipment with a hydrophone. As a result, it is found that the minimum threshold value for the main collision of individual particles perceived by hydrophone increased as the supply flow rate and the size of sediment particles increased.
