The Application of Multibeam Bathymetry Systems in Process Control and Quality Detection of Channel Dredging Operations.

To better understand the application of multibeam echosounding (MBES) system in channel dredging, we determined the processes affecting error and data quality and clarified standard methods of multibeam parameter selection under different conditions. Accurate bathymetric data can be used to interpret geological processes and calculate the volume of materials added to or moved from the channel bottom. MBES can also be used to investigate bottom sediment coverage and to design the dredging plan in the pre-construction process. The MBES provides real-time accurate water depth for monitoring the dredging process and guiding the engineering schedule. By measuring the water depth of a dredged channel and comparing it with the design depth we can determine whether the engineering design requirements and technical specifications have been meet. Furthermore, the use of MBES has many advantages in channel dredging. It can play an important role in the dredging engineering design and is a good tool for inspecting dredging results, providing a reference for future related work. [ABSTRACT FROM AUTHOR]
