【摘要】 古洪水的研究可以了解近期实测资料中尚未反映出来的洪水特征以及洪水的历史变化规律,从而加深对洪灾成因的认识,为制定减灾措施提供可靠的依据。对古洪水的定义、研究进展进行了阐述,指出古洪水的研究重点是由洪水沉积物保存下来的可分析的沉积记录。总结了古洪水的研究范围及所完成的工作。着重评述了古洪水在工程水文中的三大作用,依次为古洪水在极值洪水分析中的作用,古洪水在设计洪水中的作用,古洪水在检验PMP/PMF成果中的作用。更多还原

【Abstract】 The research on paleo flood is helpful for understanding the flood characteristics and history variation law which is not reflected by the gauged data in modern times,so as to better understand the genetics of flood disaster and provide reliable base for making disaster mitigation measures.This paper presents the definition and research progress of paleo flood and points out that the main points of paleo flood research is the deposit recorder of flood.We summarize the research scope and the completed research work;introduce 3 roles of paleo flood in engineering hydrology,namely,extreme flood analysis,design flood and PMP/PMF result check.更多还原
