滦河流域“12.8”洪水特性及其防洪调度探析

Analysis on characteristics of“12.8 Flood”occurred in Luanhe River Basin and its flood control operation

2012年8月,滦河流域分别受高空槽、低空切变线及10#台风"达维"影响,发生了几场强降水过程,降雨量较多年同期偏多近2成。从而,流域多条河流发生了自1994年以来的大洪水,沿线县(市)受到一定程度洪水威胁。通过对"12.8"洪水主要降雨过程、洪水特性及调度特点分析,为今后加强滦河流域科学有效防御洪水提供参考与借鉴。

In August 2012, Luanhe River Basin was impacted by both the upper trough with lower-level shear line and the Typhoon＂ Damrey＂ the lOth typhoon of the year respectively, whereat several strong rainfalls occurred with the precipitations about 20% more than those occurred in the same period of many years. Consequently, severe floods since 1994 happened from several rivers in the basin and then the cities and counties along the rivers were threatened at a certain scale. Through the analysis made herein on the main precipitation processes, the flood features and the characteristics of the relevant flood control operations of the＂ 12. 8 Flood＂, some references are provided for strengthening the scientific and effective prevention of the flood most likely to occur in Luanhe River Basin.
