Establishment and Validation of the Sediment Carrying Capacity Formula Based on Multiple Linear Regression Method
摘要
Abstract
Based on the multiple linear regression analysis method, the different sediment carrying capacity formulas, which contain different combination circumstances of hydraulic factor and sediment factor,are set up with 2549 groups of flume sediment data. 2850 groups of natural river sediment data are used to verify the functions. It proves that the velocity is the most important factor, but the sediment factor can not be ignored. Meanwhile, the paper discusses the pros and cons of hydraulic gradient in studying sediment carrying capacity, and analyzes the simplified form of the sediment carrying capacity formula, also points out the characteristics and advantages of the formula that contain different impact factors. It provides a reference for calculating sediment carrying capacity in engineering practice.关键词
