摘要：Based on results of detection hydroacoustic, backscattering value from the first reflection (E-1) can describe the roughness and from the second reflections (E-2) can describe the hardness of sea floor. The objective of this study was to analyze the relationship between grain size, roughness and hardness with backscattering values using the hydroacoustic method. The results showed that the roughness, hardness, and diameter size fraction of fine sand substrate were greater than that of muddy sand substrate. The backscattering values of very fine sand substrate were also greater than that of muddy sand substrate.
