沿岸输沙计算研究综述

Review of theoretical models for long-shore sediment transport

沿岸流输沙是波浪和波生沿岸流共同作用引起的沿岸纵向泥沙运动,是海岸带重要的泥沙搬运方式。自20世纪50年代以来,国内外许多学者对这一课题进行了研究,产生了很多理论公式,本文简要分析了各家的理论思想,根据不同的研究思想将诸多公式分类,简单论述了这些公式的优劣和实用性,并提出了一些沿岸流输沙研究中存在的问题。在文章的最后,介绍了理想沙质海滩稳定曲线的研究进展,并对其中存在的问题做了简单阐述。

The longshore sediment transport is one of the most important sediment transport modes. It is a kind of longitudinal sediment transport caused by waves and wave-induced longshore currents. Since 1950, the long-shore sediment transport has been studied by many scholars. They suggested a lot of theoretical formulas. In this paper, their formulas are classified into different models. And their advantage and disadvantage are an- alysed, and some problems are set forth to improve long-shore sediment transport research further. In the last part, several ideal sandy beach stable curves are described, and a brief review and some issues of related re- search progress are set forth also.
