| Grain size trends in relation to net sediment transport pathways are examined, using some commonly-used grain size parameters. The results of the trend analysis (for 15 types of the trends) are compared with a known net sediment transport pathways established on the basis of the sandbank hydro- and sediment-dynamics (i.e. general water and sediment movement patterns and bedform asymmetry). It is shown that: (1) the results for grain size trends associated with "a worsening in sorting along the transport pathways" have little similarity to transport pathways; (2) the results for grain size trends associated with "an improvement in sorting along the transport pathways" have relatively high degree of similarity to the identified pathways; and (3) the... |

| Sixty samples were collected on the Gootebank to assess the application of the McLaren sediment transport model on a tidal sandbank environment. Residual sediment transport directions were deduced and compared with the results of a detailed bedform analysis obtained by side-scan sonar recordings. Results show that when sediments become finer and better sorted, the corresponding skewness becomes more positive which is in contradiction with the sediment transfer function of McLaren and Bowles (1985). Comparison of the directions of residual sediment transport deduced from bedform analysis and from the sediment trend analysis shows that a good similarity is reached in the adjacent swales and that an offset of 90° exists on the bank. The transversal grain-size... |
