The flood peak is higher, the flood volume is greater and the flood duration is longer.
洪水特点是峰高量大、持续时间长。
The total flood volume is reduced, the flood duration is prolonged, the peak flow is decreased dramatically, and the flood hydrograph is characterized by the rapid rise and mitigatory recession;
洪水总量减少，洪水历时延长，洪峰流量显著降低，洪水过程线表现为涨洪陡、落洪慢的特点；
With the features of long duration, suddenly happening and rising, the ice flood in the Yellow River sometimes cause more intensive calamity than that of storm flood.
