补充资料:枯水
枯水 low water 无雨或少雨时期,江河流量减少,水位下降的现象。此时,河川的水主要靠流域蓄水,尤其是靠地下水补给。一些中、小河流,集水面积小,河槽下切较浅,得不到充沛的地下水补给,枯水流量很小,久旱无雨时,会出现河流干涸现象。枯水期的起止时间和历时,完全决定于河流的补给情况。中国以雨水补给的南方河流每年冬季降雨量很少,经历一次冬季枯水。以雨雪混合补给的中国北方河流,每年经历两次枯水径流阶段,一次在冬季,另一次在春末夏初,这时积雪全部融化,而夏季雨季又尚未来临。枯水流量的大小和枯水期的长短对灌溉、发电、航运、工业和城市供水有很大影响。20世纪50年代末,在长江流域的枯水调查中发现长江在四川省涪陵县境内河段的江心岩石上(即白鹤梁上),有764年(唐广德二年)以后的枯水位石刻记录163条,是可贵的历史水文资料。
