摘要:
为能及时、有效测控特殊水情,保证流量资料精度,选取彝良水文站近三年的常测法流速资料进行误差偏离计算,分析断面平均流速与单位流速的相关关系,确定简测法的具体方案,将其作为高洪测流方案的一个补充。结果表明:起点距10 m和14 m处的断面平均流速与单位流速关系密切,满足误差规定要求,可在抢测洪峰流量时使用。

Abstract: To promptly and effectively monitor water condition and ensure the accuracy of discharge data, the last three years measured velocity data at Yiliang hydrological station were selected for error deviation calcu-lation, correlation analysis of sectional mean velocity and the per unit flow rate. Concrete scheme of simpli-fied method has been confirmed and serves as a supplementary project of the high flood measurement. The results showed that the sectional mean velocity, 10 m or 14 m away from initial point, was closely related to the per unit flow rate. These results, which meet the defined requirements of error, can be used in the emergency determination of peak flow.
