    The grain size of sediments is a crucial parameter in sedimentology. The study of grain size distribution is of significant importance to submarine engineering and water conservancy engineering.In this study, we developed an acoustic reflection measurement system utilizing a self-developed, high-precision, high-frequency shallow stratigraphic profiler. The accuracy of this measurement system was validated using standard acrylic samples. Within the sediment grain size range of 0.3 to 2.5 mm, the acoustic reflection amplitude increases with grain size. However, for grain sizes between 0.1 and 0.3 mm, distinguishing them from grain sizes of 1.0 to 1.5 mm based solely on reflection amplitude is challenging. Notably, the difference in wavefront flare shapes between these grain sizes is readily apparent. Therefore, combining reflection peak amplitude with time-domain waveform analysis enables more precise sediment grain size classification.
