【摘要】 河口泥沙通量的研究既是与全球变化研究有关的理论课题 ,也是与河口工程、经济生活关系密切的现实课题 ,本文系统地介绍了国内外关于河口泥沙通量研究的进展。泥沙通量研究多采用水文统计、机制分解、数学模型的方法进行 ,水文统计和机制分解无法达到预报的高度 ,相比之下 ,数学模型的优点很多 ,但由于河口海岸地区的泥沙运动规律复杂 ,其物理机制尚不完全清楚 ,阻碍了河口泥沙数学模型的发展。在深入分析基础上 ,文章就今后的河口泥沙通量研究工作提出了建议。更多还原

【Abstract】 Study on estuarine sediment fluxes has both scientific and engineering significances.This paper summarized the new development and progress in the study of estuarine sediment fluxes.Research on sediment flux was mostly conducted by the method of hydrological statistics,calculation of sectional flux,numerical model.Both hydrological statistics and calculation of sectional flux cannot predict the sediment transport process,so the numerical model is more useful.However,the development of estuary sediment model is hampered because the physical mechanism of estuarine sediment transport is still poorly understood due to its complexity.Based on the analysis,the paper prospects the future research work in this field.更多还原
