该文综合介绍了近几年黄河下游调水调沙期间出现的洪峰异常增值现象及其发生的水动力学机理、概念验证及与其紧密相关的极细沙减阻和水槽试验研究成果,并介绍了黄河水利科学研究院利用“多沙河流洪水演进与冲淤演变数学模型”对洪峰增值实际过程的验证及预报情况等。对于泥沙减阻力学及减阻效应方面的研究任重而道远,该文旨在抛砖引玉,借此希望更多的学者能够关注这一问题的研究。
This paper presents a brief introduction of the anomaly value-added phenomenon of flood peak and its hydrodynamics during the period of water and sediment regulation in the lower Yellow River in recent years, the proof of concept and the related research results of fine sand sedimentation reduction and tank test The Yellow River Institute of Hydraulic Research using “multi-channel river flood evolution and mathematical model of erosion and deposition ” on the peak value of the actual process of verification and forecasting. The research on sediment drag reduction and drag reduction has a long way to go. This article aims to attract more scholars to learn more about this issue.
