摘要
根据流速—悬沙含量共谱密度函数与悬沙运移净通量的联系,文章讨论了平均项和潮频范围内各波动分量净输沙作用量级分布和空间格局,说明金塘水道悬沙净输送作用以平均项为主,12h项为辅,陷捕效应和再悬浮效应是形成12h项净输运贡献的重要机制。
As the cospectrum between water current and suspended sediment concentration reflects the spectrum of net sediment transport flux in domain of frequency,the contribution of factors within tidal band has been discussed on both frequency shared and spaeial distribution.The data from 13 24-hour-stations suggest that the strongest contribution comes from long-term variation as a form of time average term for such short series,while the secondary is 12-hour term dominated by trapping and resuspension effect.
