Abstract

西江中游由于缺乏湖泊对洪水的调蓄，加之防洪堤不断地加高加固引起洪水归槽，加强了洪水遭遇效应，导致洪水发生的频率和强度发生变化，其一致性受到影响。多输入单输出水文相关模型(MISOHRM)可以较好地分析某一站点的水文要素受到其上游多个站点因素的影响情况，结合非一致性水文频率计算原理，提出适用于非一致性洪水序列的频率计算方法，该方法将对变化环境下的堤防建设和流域防洪减灾规划制定，具有一定的参考价值。 With the higher and harder levees and no lakes to storage the flood at the middle stream of XijiangRiver, the encounter and return to main channel of flood were strengthened and the frequency and intensity of flood were changed, and the consistency was affected. The Multiple Input Single Output Hydrological Relevant Model (MISOHRM) was used to analyze the affection of multiple affecters upstream to the certain hydrological station downstream, with the principles of inconsistent hydrological frequency calculation, the algorithm of inconsistent flood series frequency calculation was put forward. This algorithm could be useful to the construction of levees and the formulation of flood control planning in the changing environment nowadays.
