Abstract

Abstract

The bottom boundary layer (BBL) flows are the important processes in estuarine and coastal dynamics and sediment transport.A high-frequency acoustic doppler velocimeter (ADV) has become the most effective tool in the BBL turbulence observations.Unfortunately, the filed observations are frequently interfered by the status of ADV-attached frame stability, and raw data is significantly contaminated by ambient waves and currents, bedforms and so on.To date, the post-processing procedure for turbulence parameters is far from being a standard method.On the basis of previous works, the paper proposed a comprehensive technical method for the post-processing, including status check, data quality control, coordinate rotation, despiking and filtering.Some potential errors arisen from these processing processes were analyzed in a greater detail,and the evaluation in accuracy of post-processing was discussed.The present contribution may provide a technical support for the ground-truth investigation of turbulent mixing and sediment transport in the coastal ocean.
