瀑布沟水库汛期洪水分期特性研究

根据瀑布沟汛期洪水资料和环流形势等天气资料,分析瀑布沟汛期洪水与环流形势的关系,通过数理统计、模糊分析等方法分析了瀑布沟汛期洪水的分期特性,分析表明,瀑布沟汛期洪水存在较为明显的主汛与后汛之分,分期时间在8月20日左右。分析结果为瀑布沟水库分析分期设计洪水、汛期汛限水位动态控制等提供了良好的技术支持。

Study on Flood Season Staging for Pubugou Reservoir

Based on the flood and its corresponding atmospheric circulation data,analysis of the flood season staging was made through mathematical statistics,fuzzy analysis method and analysis of the relationship between flood seasonal change and atmospheric circulation.The result shows that the flood at the Pubugou Reservoir before the August 20th is obviously different from the flood occurred after the August 20th.There is clear difference between main flood season and later flood season.The research supports for the seasonal design flood estimation and the research of dynamic limited water level in flood season.
