| Abstract: | According to the National Technical Standard for Determination of Sediment Size in Open Channels, determination results by using method of particle size meter should be corrected based on the experimental analysis of standard samples due to influence of mass fall and diffusion. In this study, suspended sediment samples at 16 representative stations over China are collected and the grain size ranges from 0.062 to 0.5mm. The determination results by using method of particle size meter are contrasted with single particle fall analysis method which is used as the standard method. Then correction methods are presented and results can fully satisfy the standard of the quality examination in particle size analysis. |
