Utilisation of the Application of High Frequency Acoustics to Sediment Processes for Mine Burial Prediction

Abstract

Over the past decade, high frequency acoustics, 0.5 MHz-5 MHz, has made significant contributions to the measurement of nearbed sediment processes. The capability of acoustics to provide co-located high temporal and spatial resolution profiles of the bed forms, the hydrodynamics, and the suspended sediments, is providing new insights into the interactions and feedback mechanisms of sediment transport. Acoustic instrumented mines, AIM's, were developed that could utilize this concept of acoustics, formulated for sediment studies, and apply it to scour burial. The AIM's were designed to measure not only the behavior of the mine, is the roll, pitch, heading, and percentage burial, but also the near-field hydrodynamics, sediment movement and bedform changes, that cause the burial.
