中文摘要：

最后二十年在自然的河里为浅流动见证正常数字模型的开发和应用程序。然而，直到现在，为有不一致的沉积运输的流动没有如此的模型。这篇论文论述 1D 在冲积的河里模仿流动和不一致的沉积的非能力运输的正常模型。活跃的层明确的表达被采用解决床沉积作文的变化。在集中的有限体积斜坡 LImiter (SLIC ) 的框架策划，一个表面坡度方法被合并达到正常答案到管理方程。建议模型与不规则的地形学靠着典型盒子被测试，包括挖出的沟再装满，沉积由于沉积由于山崩水坝失败过载和洪水流动。在计算结果和测量数据之间的协议是令人鼓舞的。比作一个非正常的模型，正常模型特征在复制舞台，速度和床变丑改进了性能。它应该在冲积的河里为不一致的沉积运输建模发现一般应用，特别在床地形学主要是不规则的山区。

英文摘要：

The last two decades have witnessed the development and application of well-balanced numerical models for shallow flows in natural rivers. However, until now there have been no such models for flows with non-uniform sediment transport. This paper presents a 1D well-balanced model to simulate flows and non-capacity transport of non-uniform sediment in alluvial rivers. The active layer formulation is adopted to resolve the change of bed sediment composition. In the framework of the finite volume Slope LImiter Centred （SLIC） scheme, a surface gradient method is incorporated to attain well-balanced solutions to the governing equations. The proposed model is tested against typical cases with irregular topography, including the refilling of dredged trenches, aggradation due to sediment overloading and flood flow due to landslide dam failure. The agreement between the computed results and measured data is encouraging. Compared to a non-well-balanced model, the well-balanced model features improved performance in reproducing stage, velocity and bed deformation. It should find general applications for non-uniform sediment transport modelling in alluvial rivers, especially in mountain areas where the bed topography is mostly irregular.
