Abstract:The key to the Problems of probing the concentration of suspended sediment in water and its variationwith acoustic equiprnent is for to calibrate the Obboned data. Carbining the acoustic bebotter intensity data withthe real concentration of suspended sediment from water Samples collected for the Changjiang Estuary, three in-situcalibration metyods for transfrming transforming measured sediment are induced. Results show that the discrepancies for cali- brated values given by characteristic the calibration and real ones are less than the values given by single shot method,and the statistted are is 20% approximately. The calibration on charactedstic times is praCtical and sabler than simultaneous calibration.
Keywords:Suswted sedirnent   acoustic probing   in-situ calibration
