浑江桓仁水库径流特性分析

Analysis of Hunjiang river runoff characteristics in Huanren reservoir

最后本文以桓仁水库为例，计算了考虑防洪预报误差、防洪调度滞时和洪水起调水位三种因素的防洪预报调度方式的风险率。

In this dissertation , taking Huanren reservoir as an example , the risk ratio of flood control forecast operation is calculated considering the flood forecast error , flood operation delay time and flood limitation water level .

汛期分别选择对各旬径流最有影响的预报因子作为旬径流预报的变预报因子，结合多元线性回归方法和BP神经网络方法构建了桓仁水库汛期旬径流预报模型。

The most influential predictors for each ten-day in flood season are respectively selected as the variable predictors , combined with the multiple linear regression method and BP neural network method , the ten-day runoff forecasting models are constructed .

文章简要分析了桓仁水库建库前后年径流变化情况及洪水的变化情况。

The paper analyses the changes of annual runoff and flood before and after construction of the reservoir .
