Abstract

Abstract

The horizontal suspended and bed-load sediment transport in the bottom boundary layer were computed by applying a one-dimensional parameterized scheme to the in-situ data obtained from two stations in the Bohai Strait during a winter field investigation in 2018. In the parameterized scheme, a simplified one-dimensional advection-diffusion equation was used to calculate the vertical suspended sediment concentration in the bottom boundary layer. Aiming at verifying the reliability of the parameterization scheme, two models of bed shear stress calculation, four critical bed-shear stress methods and two advection-diffusion solutions were compared based on the observations. It showed that: (1) bed shear stress calculated by different models are fairly consistent; (2) the critical bed-shear stress is affected by sediment cohesive effects; (3) stratification effect of sediment concentration and the difference of critical bed-shear stress with different particle size fractions need to be considered solving the one-dimensional advection-diffusion equation. Based on the optimal parameterization obtained from the comparisons, sediment transport of the two stations was further calculated: (1) during resuspension events, the ratio of the horizontal suspended sediment flux within 5 meters above bottom accounting for the suspended sediment flux throughout the entire water column which is about 21% in T01 and 17% in T02 is significantly higher than the ratio of the water flux within the same layers; (2) the mean suspended sediment flux estimated by the parameterization scheme in winter is about 16% higher than the result estimated from the conventional method which ignores the vertical variation of suspended sediment concentration in the bottom boundary layer; (3) bed-load transport is generally 2 orders of magnitude smaller than the suspended load transport.
