1·The Alekceef's method is a main method to calculate flood hydrograph in the medium and small project planning and designing.

“阿氏法”是中小型工程规划设计中洪水过程线计算的主要方法。

2·The main factor which may have a strong impact on such a deviation is the sample errors of certain flood volumes in a flood hydrograph.

影响偏离的主要因素为时段洪量设计值的抽样误差和典型过程线的形状。

3·The difference is obvious between the computed flood hydrograph according to the traditional method and observed flood hydrograph, especially flood peak.

目前常用矩法估计瞬时单位线，据此还原的洪水过程与实测洪水过程之间，特别是洪峰点之间，常具有明显的差别。

4·Due to the capability for simulating dam-break and predicting flood hydrograph, a dam-break model is of tremendous importance to the disaster control and reduction.

溃坝模型可以模拟溃坝过程，预测溃坝洪水过程线，对防灾减灾有着重要意义。

5·The flood characteristic of the main stream of Songhua river is that the flood is mainly from Nenjiang river, the flood hydrograph is gently, the time of propagation of flood peak is longer.

松花江干流洪水特征是：洪水主要来自嫩江，洪水过程平缓，洪峰持续时间长。

6·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；

7·The rational formula method and the unit hydrograph method are used and compared in the calculation of the design flood for the Guangzhou pumped storage station in this paper.

应用广东推理公式法和单位线计算广州抽水蓄能电站水库坝址处设计洪水，并对两方法计算的结果进行分析比较。
