Optimization Scheme Analysis of Single Sand Sampling Position in Qianjiang Hydrology Station
The sediment characteristics of Qianjiang Hydrology Station have changed gradually due to the influence of water projects in Hanjiang River.The error of sediment test results becomes larger due to the large dispersion degree of single break sediment relation curve,the lower precision and the weaker representation of single sediment sampling position.In order to solve this problem,the measured hydrological data of single sediment and broken sediment in 5 typical years in 2011,2014,2016,2017 and 2018 were used to optimize and analyze the sampling location of single sediment,and verified according to the measured sediment data from 2019-2022.The results show that the optimized single sand sampling position is more representative,the single break sand relation meets the specification and has higher precision,which can be applied to the actual production test of the station and improve the sediment test accuracy.
