皇庄站单断沙关系与枯季含沙量优化测次探讨

Probe into Survey Frequency Optimization of Relation of Single-section Sand and Sediment Concentration of Dry Season in Huangzhuang Station

根据皇庄测站的特性和断面变化情况，对单～断沙关系进行了分析，并确立了单～断沙关系的最优方案；针对枯季输沙率测验优化测次布置，枯季1～4月、11～12月输沙率测验测次每月不少于2次即可满足各项特征值的精度要求。

The single-section relation was analyzed according to the characteristic of Huangzhuang survey station and the cases of section changing, and the best scheme of single-section relation was established. In dry season, the survey frequency should be no less than twice, which can meet the demands of accuracies of all eigenvalues.
