A cusp catastrophic model is founded on the stability of an inclinedbedding slope from catastrophic theory, and a formula of the total potential energy and a criterion condition are derived.
The study of the hydrodynamics indicates that the reliable data of the paleocurrent can be collected through features of the size grading, low angle inclinedbedding and the backward bedding.
沉积水动力学分析表明可以从槽状交错层理特征中的粒序、低角度斜层和逆向层理提取可靠的古流信息。

These inclined beddings can be divided into 4 bedding assemblages to represent different development stages of tidal sand ridges and to correspond to different postglacial sea-level rise periods.
