蒿店水文站全年巡测方案探讨

通过对蒿店水文站平水期逢0日测流、洪水期施测水流沙全过程的巡测与驻测两种不同测验方式实测资料的统计分析,用巡测推求的流量符合《水文巡测规范》第4、5、3条三类站年总量允许误差不超过5%、汛期总量允许误差不超过6%的规定;依据《水文巡测规范》第4、5、9条各年输沙量相对误差在5.0%允许范围内,据此可以确定全年巡测方案。

Through the statistical analysis of the measured data of the whole process of flow measurement every 0 day and flow and sand measurement in flood season in Haodian Hydrological Station,the discharge calculated by patrol measurement accords with the stipulation of Article 4.5.3 of the"Specification for Hydrological Tour Gauging",the annual total allowable error of three types of stations does not exceed 5%,and the total allowable error of flood season does not exceed 6%.According to Article 4.5.9 of the"Specification for Hydrological Tour Gauging",the relative error of each year’s sediment transport is within the allowable range of 5.0%,based on which the annual patrol survey plan can be determined.
