水动力数值模拟结果与经验公式相结合，来确定沉积物的搬运速度和搬运方向。预测结果与放射性砂的示踪实验的比较表明，盖德等人的方程的实用价值。该区底荷搬运模式与沉积学和地貌学的资料吻合，从而提高了分辨能力。发现英吉利海峡中部的底荷分区，对于研究砂的运动是非常有意义的，尽管该区的海底物质并未显示出有明显的运动。该区为未冲蚀区，被搬运的是细粒沉积物，底荷的收敛区位于多佛尔海峡的西南部，这与先前的位于多佛尔海峡的观，点不同。沿着法国海岸环绕收敛区的搬运路径引起砂从英吉利海峡朝北海南部运移。
Hydrodynamic numerical simulation results combined with empirical formulas to determine sediment transport speed and handling direction. A comparison of the predictions with the tracer experiments with radioactive sand shows the practical value of the equation of Gade et al. The bottom load handling model of the area is consistent with the data of sedimentology and geomorphology, thus improving the resolving power. The discovery of the base load subregion in the middle of the English Channel is of great interest in the study of sand movement, although the seafloor material in the area did not show any significant movement. The area is an unetched area, where fine sediments are being transported and the bottom charge converging zone is located in the southwestern part of the Dover Strait, which is different from the previous view and point in the Dover Strait. The removal of the sand from the English Channel towards the southern part of the North Sea has led to the removal of the sand along the convergence zone of the French coast.
