A nonparametric kernel estimation of the flood frequency with historic information is presented in this paper. The limitation in assuming a distribution type is overcome.
本文提出了在有历史洪水情况下洪水频率的非参数核估计方法，克服了现行方法假定分布型式的局限。

Robust estimation has been applied in flood frequency analysis.
近年来，稳健估计在洪水频率分析中的应用已被提出。

It can be seen that the frequency curve calculation is basically reasonable and show the estimation of "1482 flood" return period is rational after putting palaeofloods into flood series.
