Detection of the true depth of the bottom beneath dense submersed aquatic vegetation is problematic using conventional hydroacoustic bottom tracking approaches. This may lead to underestimation of bottom depth, erroneous bathymetric maps, and overestimates of dredging quantities. A hydrographic data...
