Record of past floods of the Nile during the wetter North African Humid Period (7,500-9,500 yrs ago). Top: thickness of flood layers with green (yellow) thicker (thinner) layers indicating stronger (weaker) floods and the median thickness in black. Intervals of stronger floods also have a larger variability. Bottom: wavelet analysis of the thickness record with strong and significant signals (yellow) showing a strong influence of El Niño Southern Oscillation on flood variability.
