According to the analysis of the big floods in the Jianghuai Valley, three new conclusions are given as follows:(1)there is generally the big flood in the Jianghuai Valley around the peak-valley year of sunspot activity;(2)there is probably the big or huge flood in the Jianghuai Valley around the year of magnetic cycle transformation of sunspot activity;(3)there is more probably the big or huge flood in the Jianghuai Valley in the same or next year of El Nino around the year of magnetic cycle transformation of sunspot activity.These conclusions can provide certain theoretical basis for the flood forecast of long or over-long term.
