摘要
综合分析了20世纪80年代以来全新世古洪水水文学研究进展,简述了古洪水事件的判别以及如何更加准确地确定古洪水发生时的洪峰水位,在非基岩峡谷段确定其行洪断面难度.分析了古洪水洪峰流量重建的水位流量法,比降面积法,ArcGIS耦合HEC-RAS模型法.总结了在计算出古洪水洪峰流量后对其可靠性验证的两种方法.指出近年全新世古洪水水文学研究方面存在的主要问题,提出古洪水水文学研究的主要趋势.
After a comprehensive analysis of the Holocene flood hydrology progress since the 1980 s,the paper summarizes how to distinguish the palaeoflood events as well as how to determine the peak water level of the flood more accurately,and to determine the difficulty of palaeoflood discharge sections on non-bedrock gorge.It also analyzes the level-discharge method,slope-area method and surface-control method of the reconstruction of the palaeoflood peak flow.The paper summarizes two methods to verify the reliability of it after calculating the palaeoflood peak flow.Finally it also points out the main problems of palaeoflood hydrology Holocene in recent study,and puts forward to the main trends of palaeoflood hydrology study.
