应用抵偿河长原理整编洪水及潮流量资料

我国颁发的水文资料整编规范,将“抵偿河长法”列作流量资料整编的基本方法。本文根据抵偿河长的原理计算时段内上、下游站的时段平均流量要满足直线变化的假定,采用上游96km处的德庆站水位与高要站流量建立关系,推求高要站的全年流量资料,基本获得成功,作为示例对整编全年洪水及潮流量资料的方法进行分析介绍。

Method of Cowpilation of Annual Data of Flood and Tidal Voluml by Principle of Characteristic River Length

In the norms for hydrologic data compilation promulated in our country, method of characteristic river length has heen listed as the basic method for flow data compilation, Based on principle of charaeteristie river length has heen listed as the basie method for flow data compilation Based on principle of characteristic river length, this paper assumed that average flow between the upstream and downstream stations in the calculated time interval should satisfy linear change. The stage at 96 km upstream Deqing station was used for setting up the relation with discharge at Gaoyao station, thus, the annual flow data at Gaoyao station was successfully calculated. This ease was analized and introduced as a method for the compilation of annual data of flood and tidal voulme in this paper.
