Abstract: The measurement and estimation of suspended sediment using ADCP is based on the theory that the strength of acoustic return signal is directly proportional to silt concentration in water.In actual surveys,due to many disturbing factors,the signal strength obtained from ADCPs is found to be in nonlinear relationships with suspended sediment concentration.Compared with conventional regression models,BP methods can greatly increase measuring accuracy.
