摘要： 根据水流泥沙运动和水质（温度及浓度）扩散传播基本理论，建立了平面二维水流泥沙和温度及浓度场数学模型，以之研究水库、河道、河口水流及其输移物质运动规律，并采用有限体积法和有限元法来离散和求解这些模型方程组，用以模拟河道水流及其输移物质运动规律。该模型计算过程稳定，计算速度快，已在诸多工程中广泛应用，并得到原型观测成果的检验。

Abstract: Based on the basic theories of sediment, flow movement and the diffuseness of temperature and concentration, a 2 - D mathematic model describing sediment - carrying flow, temperature and concentration fields used in reservoir, river channels and estuaries was established. The limit volume method and the finite element method were adopted to solve the control equations of 2 - D mathematic model. The calculation process of this model is stable and computational velocity quick.This model has been widely used in engineerings and detected by field observed results.
