此轮强降雨期间,湖南省多座水库通过开闸泄洪,拦洪削峰,起到了很好的作用。但水库泄洪也引起一些网友担忧。很多网友质疑:水库闸门全开,下游怎么办?不开闸淹上游,开闸是保上游淹下游。
针对网友担忧、质疑,7月3日,省水利厅水利专家回复:水库泄洪是在入库流量大幅增加的情况下,防止出现漫坝溃坝险情,控制洪峰流量,更好保护大坝和下游安全。

水利专家解释,任何一座水库都有容量极限,在长时间降雨情况下,水库积水过多,超过水库容量极限,就要通过泄洪,减轻水库压力,才能降低溃坝风险,保护大坝和堤防安全。
什么情况下水库需要泄洪?“当水库水位接近或超过汛限水位时,为避免水库超负荷运行和溃坝风险,就要进行泄洪。”水利专家说。
