摘要
为实施黄河水量精细调度,建立符合实际的水量调度数学模型,需要通过水量平衡计算,提供不同区段的水流传播时间和河道径流损耗等水文资料。通过对河道径流损耗量的分析计算,探讨了在水量平衡计算中影响河道径流损耗量的误差源及其对计算结果的影响程度,并提出了对各项误差源的控制措施。
In order to implement accurate water resources scheduling on the Yellow River and build a mathematical model for water regulation in accordance with the practical condition, it is necessary to provide hydrological data such as duration of flood routing on different reaches and runoff loss. Through analysis and calculation of the runoff loss in channel, this paper gives a study on the error source effecting channel runoff loss in calculation of water balance and its influence on the calculated results, and puts forward the concerned measures to control various error sources.
