摘要
本文提出建立1981—1990年南城子天然洪水和实测洪水相关关系,根据1991—2012年南城子实测洪水推求天然洪水,实现对南城子洪水系列的延长。通过绘制临近各水库洪峰、洪量与流域面积关系图验证成果合理性。利用延长后的洪水序列进行设计洪水复核和调洪演算,取得了良好的结果。复核结果表明:该方法在观测资料缺失的条件下延长洪水序列的合理性,为类似问题提供参考和解决思路。
This paper established the correlation between natural flood and measured flood（1981-1990） in Nanchengzi control station, according to the measured flood （1991-2012） in Nanchengzi control station, the missing natural flood could be speculated, and the series of nanchengzi flood could be prolonged. The reasonableness of the results was verified by drawing the relational graph of flood peek , flood volume of Reservoirs near Nanchengzi and basin area. The the prolonged flood series was used to design flood recheck and flood regulation calculation, and good results were obtained. The result of recheck shows that the method is reasonable to prolong the flood sequence under the condition of missing observation data, it provides reference and solution to similar problems.
