中文摘要： 河流动力学水沙数值模拟是深入研究水沙运动客观现象及规律的重要手段，由于数学模型缺乏标准可量化的评价指标体系，造成模拟结果的综合性能无法客观衡量，致使模型对水沙基本理论反馈作用和对河道水沙发展趋势预测可靠性受到质疑。因此本研究旨在构建首个行业规范的水沙数值模拟多目标可量化评价体系，甄选经典实验室数据和多沙河流实测原型资料集成模型测试案例题库；基于建模原理和水文观测数据遴选表征水沙输移及其伴生过程作为模型评估单项指标；借助系统工程学研究单项指标无量纲方法、单项赋权及合成模型，实现面向WEB的水沙数值模拟量化评价系统，改变我国目前数值模型评价以人为主观感觉为主导的现状，有利于深化对泥沙基本理论和数学模型理论的认识，促进水利行业数值模拟标准、规范化发展。

英文摘要： River dynamics of water and sediment study of numerical evaluation is an important means to further study on the objective phenomenon and regularity of water and sediment movement.The Feedback Effect of water and sediment basic theories and predicted reliability of water and sediment development trend in river are oppugned due to the lack of evaluation index system which is criteria measurable, so that the comprehensive properties of simulation results can hardly be objectively measured.Therefore, the aim of this study is to construct the first water and sediment numerical simulation of multi-objective evaluation system in the industry. The classic experiment data will be selected, as well as that of scenario cases of integrating model of observed sediment-laden river data.Transport of water and sediment and its associated process as single index are based on modeling principles and hydrological Data.Water and sediment numerical simulation and quantization evaluation system oriented to WEB is based on non-dimension solutions of Systems Engineering, single index weight determining method and synthetic model.The present situation that numerical simulations judged by subject feeling will by changed via this study. The understanding of sediment basic theories and mathematic model theories will be deepened, so that t
