黄河防御洪水方案 关键技术研究 Key Technological Issues of Designing Flood Control Schemes of the Yellow River 刘红珍 Liu hongzhen 黄河勘测规划设计有限公司 Yellow River Engineering Consulting Co., Ltd. 5th International Yellow River Forum YREC 提纲Outline Introduction Challenges Research Procedures Flood Control Schemes of the Upper Yellow River Flood Control Schemes of the Middle and Lower Reaches Conclusions 黄河勘测规划设计有限公司 5th International Yellow River Forum YREC 1 研究背景 Introduction 黄河勘测规划设计有限公司 5th International Yellow River Forum YREC The problems of floods control and sediments management are complicated in the Yellow River catchment, and there are significantly serious flood and sediment disasters in the history. In order to reduce the flood losses, flood control projects have been built, including embankments, reservoirs, and flood storage and detention projects. How to utilize the flood control projects, and perform reservoirs and flood storage and detention projects operation scientifically, so as to reduce the flood losses, is the main target of the project. 黄河勘测规划设计有限公司 5th International Yellow River Forum 1.1 洪水来源及特点 YREC Flood sources and characteristics From Toudaoguai to Sanmenxia Characteristics: From the upstream of Big peakflow, the Lanzhou station Toudaoguai High sediment Characteristics: concentration Long duration, High water volumes Lanzhou Huayuankou Sanmenxia From Sanmenxia to Huayuankou Characteristics: Big peakflow, Short forecast intervals 黄河勘测规划设计有限公司 5th International Yellow River Forum 1.2 干流重点防洪河段 YREC Key sections for flood control of the mainstream Ningxia-Inner Mongolia Reach ( 5000m3/s~6000m3/s) Lanzhou city ( 6500m3/s) Aishan (11000 m3/s) Huayuankou (22000 m3/s) 黄河勘测规划设计有限公司 5th International Yellow River Forum 1.3 防洪工程现状 YREC The status quo of flood control projects The upper Yellow River: Embankments Longyangxia reservoir Liujiaxia reservoir 黄河勘测规划设计有限公司 5th International Yellow River Forum The middle and lower Yellow River : YREC Flood control Upper-blocking, Lower-draining, projects system Both banks divided-blocking. Lower-draining Upper- blocking Both banks divided- blocking 黄河勘测规划设计有限公司 5th International Yellow River Forum 1.4 近年来防洪形势变化 YREC The changes of flood control situation in recent years Affected by the use of the Longyangxia and Liujiaxi
