It is well known that paleoflood predictions must depend on its occurrence rule.However,available historical records do not provide long enough temporal scale for identification of emergence law of flood events.It is very important and necessary to discover and understand floodwater geological records.The pluvial geological records of Jiangling area in Jianghan Plain,show that the area revealed 18 flood events during the last 3000 years.The paleoflood events corresponded to cold and wet climate.With the help of power spectral analysis,it is found that paleoflood events include 26,31,36,43,52,79,110 a cycles.It is indicated that solar activity may be driving factor of paleoflood in Jiangling area.
