Probabilistic Characterization of Sediments Using a Combined Geotechnical and Geophysical Approach
… from Portable Free Fall Penetrometers (PFFP) and Chirp sub-bottom profilers for enhanced shallow-water sediment assessment. First, a probabilistic machine learning model, combining Random Forest and a Bayesian 1D Convolutional Neural Network, is developed to classify sediments based on full PFFP …

Investigation of the Relationships Between Geotechnical Sediment Properties and Sediment Dynamics Using Geotechnical and Geophysical Field Measurements
… are reflected in acoustic, and specifically chirp sonar measurements. The findings of this research support the capability of portable free fall penetrometer to estimate sediment properties in topmost layers for different soil types such as friction angles, with an accuracy of ± 1° and …

Derivation of Acoustic and Physical Properties from High-Resolution Seismic Reflection Data
… This was achieved using a single channel Chirp sonar (1.5-13.0 kHz) and a Boomer sonar (0.2-4.0 kHz) towed with a multi-channel streamer that provides offsets up to 80 m. These methods were applied in the Solent (Southampton, U.K.) to test empirical models that predict sediment physical …

Hydrodynamic processes and their impacts on the mud deposit in the Southern Yellow Sea, China
… (CYSM) is 3.6 ×107t a-1 based on high-resolution Chirp sonar profiles combined with cores information. Under present hydrodynamic condition, the numerical model showed that approximately 16% (1.33×108t a-1) of the Huanghe River derived sediment is transported out of Bohai Strait and nearly 7% …
