| 摘 要： | 利用声学多普勒流速剖面仪（ADCP）的声反向散射强度（ABS）,估算悬移质浓度（SSC）的相关技术日臻成熟,其原理是利用走航式声学多普勒流速剖面仪（ADCP）,采集足够频次的流速和声反向散射强度,以替代流量和悬移质浓度（SSC）的数据,在一定程度上破解了在复杂水流环境中测定和估算水体悬移质输沙率的难题。简要介绍利用声学多普勒流速剖面仪（ADCP）估算悬移质输沙率的基本原理和方法,并结合在连云港徐圩海域水文观测中的应用实例,验证该方法的可行性、可靠性和精度。

| Abstract: | The application of the acoustic back scatter(ABS)of Acoustic Doppler Current Profiler(ADCP) makes the relevant techniques of estimating the suspended sediment concentrations(SSC)become mature.The principle of it is using ADCP to collect the velocity with sufficient frequency and acoustic back scatter(ABS) intensity in order to substitute the discharge and the surrogate date of SSC.In some degree,it solved the difficult problem of measuring and estimating the suspended sediment transport rate in a complicate... |
