在对地区构造活动、地貌演变特征、河段的稳定性分析，以及现代河道断面变化特性分析的基础上，利用大量钻孔资料和河床淤积层年代测定资料，恢复了小浪底河段距今2360a古洪水期行洪断面，为古洪水流量演算提供了必要而可靠的依据。
Based on the analysis of the regional tectonic activities, the evolution of geomorphology, the stability analysis of the river sections and the characteristics of the change of the section of the modern river, a large amount of drilling data and dating data of riverbed silting layers were used to restore the Xiaolangdi River section Flood discharge flood section, the ancient flood flow calculation provides the necessary and reliable basis.
