The influence of coal exploitation and construction of Shenfu-Dongsheng coal mining area on sediment transportation of the Yellow river has been paid more attentions. Using precipitation data since 1960's, spectrum analysis is conducted to forecast precipitation in the 15 coming years and its seasonal distribution. The result shows that annual rainfall in the 15 coming years will increase by about 6%, annual rainfall fluctuation will increase and rainfall concentration in a year tends to increase, which will make flood and sediment increased.
