Abstract:: Solar activity may affect the Earth’s climate, directly or indirectly to the watershed runoff and sediment transport have a certain impact. The Morlet wavelet method has applied to analyze the changes of sediment at Longmen station and sunspot relative number from 1919 to 2007. The results show that there are different correlations between the Yellow River sediment and sunspot activity in different time periods. In same 9 year scale, there are negative correlations during 1919-1950, while there is positive correlation during 1951-2007. This indicates that the solar activity on the impact of the Yellow River sediment is very complicated.
