Monitoring the Technical State of the Underwater Section of Hydraulic and Traffic Structures by Means of Hydroacoustic Instruments

Abstract

Results of a survey of the technical state of the underwater sections of two bridges and a reservoir are presented. The techniques used to perform the studies are briefly described. The basic parameters of the equipment used — side-scan sonar and parametric profilograph — are presented. The advantages gained with the use of acoustic instruments in monitoring the technical state of hydraulic and traffic structures are demonstrated.
