一维泥沙数学模型中有关问题的商榷

Discussion on Some Problems About 1-D Sediment Numerical Model

一维泥沙数学模型多年来得到广泛的研究和发展,并在工程实际问题的研究中起到了巨大的作用。但由于泥沙运动的复杂性和理论发展的局限性,仍然存在着一些问题有待于进一步完善。针对挟沙力、饱和恢复系数、河床冲淤调整等关键问题,通过多年实际应用研究,提出了作者的认识和处理方法,以期对泥沙数学模型的发展和应用有所贡献。

One-dimensional sediment numerical model is deeply researched and developed. It plays a large role in solving the actual engineering problems. But because of the complexity of sediment movement and the limit of the theories, there still exists some problem to be perfected. Some problems are discussed, and some personal cognitions of authors are brought forward.
