Study on Transformation Method of Non-Parametric Density in Flood Frequency Analysis

DONG Jie~1, XIE Yue-bo~2, LI Yun-ling~2 (1.Shandong Agricultural University, Taian, Shandong 271000; 2. Water Resources and Environment College, Hohai University, Nanjing, Jiangsu 210098)  
It establishes historical flood-based non-parametric transformation model based on the achievements of correlated studies both at home and abroad. It analyzes flood frequency by applying the model and method of curve-fitting in Wulongkou Hydrometric Station on the Qinhe River.Morever,it also investigates and proofs the major flood happened in the Qinhe River in 1482 by utilizing a combination method of palaeofloods analysis and historical floods investigation. The results show that 1482 flood of the Qinhe River is really happened, but the discharge reached to 14,000 m~3/s is unreasonable and the return period is about 600 ~ 800 years. 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.
