As an example, the overtop failure probability of a dike under different floodwater standards is analysed using measured annual maximum flood level at a hydrological station.
以某水文站实测的年最高洪水位为例，对现有堤防在不同的设防标准下漫顶失效概率进行了分析。

Moreover, under the situation of uncertainties in large historical flood, the quantities estimated by probability weighted moments may be more robust than those by a optimal curve fitting method.
在历史洪水存在不确定性情况下，以概率权重矩法估计的参数稳健性优于优化适线法。

The method of Analytic Hierarchy Process is used to identify the risk events of flood. The probability of flood is determined by construction period and flood control standard.
