Layered Media Detection Method for Bathymetric Surveys

This case study explores a novel method for achieving CATZOC A1 navigable bottom mapping in areas with suspended mud. Utilizing multibeam echosounders operating at ultra-wide frequencies (80-400kHz), the method effectively distinguishes between different sediment layers, enhancing bathymetric survey accuracy. The study highlights the implementation of the LMD technique and its validation against traditional single-beam systems, showcasing its potential to improve dredging operations in challengi
