水灾是人类的奇祸。古往今来都是一样,洪水直接冲溃堤防工程,冲毁房屋桥梁,淹没农田以至伤亡人畜。1981年8月14—22日,凤县、太白县连降大雨和暴雨,造成历史上一次罕见的特大洪灾。宋史记载,1009年8月,凤县曾有过类似水灾“漂溺民居”,比之去年水灾危害面之广,损失之大,不可同日而语。去年水灾的特殊性,在于大气环流形成久雨,土壤饱和,继之暴雨形成洪流。据凤县气象资料:8月14—22日降雨量为363.8毫米,超过常年同月降雨量的4倍。特别是8月21日凌晨3时半开始至下午6时半,降雨106.3毫米。下午4—7时,嘉陵江流量为3,500立方米/秒,超过有资料记载的1,400立方米/秒的1.5倍。久雨酿成隐患,暴雨造成灾难。
