Mechanics and Numerical Simulation of Aggrading/Degrading Alluvial Streams with Application to the Cho-Shui (Taiwan) River

台湾的浊水溪，有其独特的特色 在其特性上高度可变， 时间以及沿其长度的沿着距离。 这项研究将利用 现有数据以及未来合作获得的数据 通过拟议的研究，在修改和推广一个 现有的泥沙输移和河流变化的计算机模型 睡觉了 修改是为了考虑沉积物的水夹带， 而现有模型仅适用于退化河流， 沉积物的沉积。 此外，沉积物的广泛变化 将包括沿河流长度的沿着组成。

A river in Taiwan, the Cho-Shui river, displays unique characteristics in being highly variable in its characteristics both, with respect to time as well as distance along its length. This research will utilize existing data, as well as future data to be obtained cooperatively through the proposed research, in modifying and generalizing an existing computer model for sediment transport and changes in the river bed. The modification is to account for water entrainment of sediment, whereas the existing model applies only to a degrading river with deposition of sediment. In addition, the wide variation in sediment composition along the river length will be included.
