潜山水文站单、断沙关系分析

Analysis of the Relationship Between Single and Broken Sediment in Buried Mountain Hydrology Station

结合潜山水文站2015—2022年的实测输沙率资料,以《河流悬移质泥沙测验规范》为依据,采用回归分析法、最小二乘法原理两种方法进行单断沙关系分析计算。结果表明,历年单断沙关系相关性较稳定,换算系数为0.9918,符合规范要求。可通过稳定、良好的关系线及得出的换算系数以单沙推求输沙,减少输沙采样的工作量。

Through combining with the measured sediment transport rate data of buried mountain Hydrology Station from 2015 to 2022,the study analyzes and calculates the single sediment failure relationship with regression analysis method and least square method according to Test Code of Suspended Sediment in River.The results show that the correlation of single break sediment relationship over the years is stable,and the conversion coefficient is 0.9918,which meets the standard requirements.By using the stable and good relationship line and the conversion coefficient obtained,the sediment transport can be deduced from the single sediment,and the workload of sediment transport sampling can be reduced.
