沙内川河床有砾石，洪水期间石块和砾石移动剧烈，河床冲刷和河岸侵蚀严重。明确洪水期间的水流和沉积物输送对于设计稳定的纵向和横截面形式非常重要。作者开发了一种新的二维河床变化分析方法，重点关注河床表面不均匀性和砾石河床泥沙输移机制。我们将新模型和常规模型应用到2011年洪水的河床变化中，对水面剖面数据进行了详细观测。我们表明，新模型是研究砾石床萨津内河洪水流量和河床变化的有用方法。
In the Satsunai river with gravel-bed, stones and gravels have moved violently during floods and severe bed scouring and bank erosion occurred. To clarify flow and sediment transport during a flood is important to design a stable longitudinal and cross-sectional form. The authors have developed a new method of two-dimensional riverbed variation analysis focused on bed surface unevenness and the mechanism of sediment transport in gravel-bed rivers. We applied the new model and the conventional model to riverbed variation of 2011 flood whose data of water surface profiles were observed in detail. We showed that the new model is a useful method for flood flows and riverbed variation in the Satsunai river with gravel-bed.
