Runoff in the Yellow River basin display sharp drop trend, which show prominently in the reach from Hekouzhen to Longmen. 271 floods of peak higher than 100m3 /s in the typical tributary of Huangfuchuan basin from 1954 to 2012 were chosen and flood features were analyzed. The conclusions is as the following. The number of flood and high annual maximum peak de - clined in recent years. Runoff and sediment transport of flood were reduced by decades, and the extent of sediment was much larg - er than that of runoff. The duration of flood rising is relatively short and peak shape is generally thin. The ratio of base flow and runoff in flood is lower when the peak discharge is higher.
