An equation is derived by theoretical analysis, to establish a relationship between suspended sediment concentrations and ADCP echo intensity output. For the survey at the entrance to Jiaozhou Bay, an ADCP is mounted on a moving vessel; the calibration coefficient in the equation is determined by in situ measurement. Then, a semi-empirical formula is obtained and used to calculate suspended sediment concentration profiles along several crosssections.
