中文摘要：
在前人研究的基础上,通过对小浪底水库异重流实测资料分析,并结合相关实体模型及水槽试验成果,研究了异重流发生、运行及排沙等基本规律.利用水库异重流运行规律及排沙特点,根据水库的上下游实际条件制定了黄河调水调沙试验水库联合调度预案.通过水库水沙联合调度实践,2004年成功塑造异重流并排沙出库,达到了减少水库淤积、优化出库水沙组合等多项预期目标.
英文摘要：
The conditions of occurrence, law Xiaolangdi Reservoir were studied based on of movement and discharge method of the density current in the observation data and laboratory test results. According to the coming flow and sediment from upstream and the requirements of downstream in 2004, a reasonable operation scheme of the reservoir for forming a density current to flush out the sediment was suggested. By jointly dispatching the input and output flow and sediment, the implementation of this scheme successfully formed the density flow and reduced the sediment deposited in reservoir.
