河床的冲刷过程分为两类。一种是低流量时的弯曲水流冲刷，另一种是高流量时的满滩水流冲刷。本文从实验和理论两个方面对河床退化和动平衡两种情况下的前一过程进行了讨论。侧向侵蚀和垂向侵蚀是曲流河发育的重要因素。在二维床层变化模型的基础上，采用数值方法对这一过程进行了模拟。
The erosion process of the river bed are classified into two categories. One is the erosion by the meandering stream at low discharges and another is the erosion by the bank-full flow at high discharges. In this paper, the former process is discussed experimentally and theoretically in both cases of the bed degradation and the dynamic equilibrium channel bed state. The lateral erosion as well as the vertical erosion is essential to the development of the meandering stream. Such a process was simulated by the numerical method based on the 2-dimensional model of the bed variation.
