摘要
Abstract
To explore the applicability of acoustic tomography technology for flow measurement in complex tidal reaches and address the accuracy degradation of traditional H-ADCP caused by ship obstruction and tidal fluctuations,an experimental study of the river acoustic tomography system was conducted at Wusongkou Hydrological Station.A simple dual-base-station installation mode was adopted,with two acoustic base stations forming intersecting measurement lines,and synchronous observations were conducted with a moving ADCP.Sectional flow velocity was processed using projection and mapping methods.The flow error was analyzed and consistency analysis was conducted.The mean relative error of flow calculated by the projection method was≤8%,satisfying the specification for ebb-tide random uncertainty;the mapping method exhibited≤6%error,meeting specifications for both flood and ebb tides.The regression model passed three validation tests,demonstrating reliable linearity.The dual-base-station acoustic tomography system enables real-time full-section monitoring,mitigates ship navigation impacts,and provides a new technical approach for Wusongkou flow monitoring.关键词
