| Abstract: | Paleoflood study is a way by which rare large flood information in a river can be obtained based on the paleoflood deposits. The relation between the top surface of the sediment and the stage of a paleoflood is the key problem in present paleoflood studies. During the study in the Yellow River valley near the Xiaolangdi village, Henan province, not only the special mark of the paleoflood slack water sediment but its tip of depositional termination have been found. The present study can help increase the reliability as well as precision of plaeoflood study. |

| Keywords: | paleoflood slack water deposit depositional termination tip high water level |
