| 摘 要： | 古洪水研究的目的是通过古洪水信息的载体--古洪水平流沉积提供古洪水水位及流量.而如何确定古洪水沉积顶面高程与其洪峰水位的关系是河床演变学至今尚未解决的难题.经过长江、黄河、海河和淮河古洪水研究之后,对此问题获得了新的认识.洪水平流沉积物尖灭点高程与其洪峰水位之间一致的关系,给古洪水研究解决了一个关键问题.

| Abstract: | The purpose of paleoflood study is to get a paleoflood peak stage based on its information carrier--paleoflood deposits. Nevertheless, how to determine their relation is always a difficult problem both in China and abroad. Foreign researchers give their results from flume experiments. On the basis of paleoflood studies along four rivers in China, this paper presents some new results. |
