Flood control management system for reservoirs

Flood disaster is one of the most damaging natural disasters in China, with annual average losses more than 200 billion yuan in recent years. After 1995 floods in the Liaohe River and 1998 floods in the Yangtze River, the governments from national to local have realized that the flood control operation of reservoirs can play a major role in alleviating flood losses but there are some problems in flood control management for reservoirs. Most of the existing flood control management systems for reservoir were established for special purposes and are lack of data share and communication with governments, it is very difficult for decision-making departments to get real-time information in short time. Thus, a national programming about flood control management system for reservoirs is presented. The paper is a summary of the outcome of national programming about the flood control management system for reservoirs in China. The background, objectives, main challenges and main contents of the programming are introduced. The main focus is on the issues of the software integration flood control management system for reservoirs. Emphasis is concentrated on the flowchart design of the system and its core components. The current system can be applied to a river control center or a single reservoir because of using the national standard databases and easily integrated into the national flood control system in the future. An application system is briefly introduced in order to understand the system.

论泾河东庄水库灰岩坝址渗漏问题

通过对泾河东庄水库灰岩坝址工程地质钻探成果特别是钻孔压水试验及水文地质成果包括区域水质、水位、水温等不连通性的分析研究,并结合流量测定三维渗漏数值模拟分析,对坝区渗漏问题进行分析和论证,进一步证明在泾河下游东庄灰岩段建坝是可行的,不会发生严重渗漏,为项目的设计、审查、决策方面参考,以促进工程前期工作的进展。     

Application of the LP-DP approach to Andong and Imha parallel reservoirs,Korea

This paper presents an application of a previously developed linear programming-dynamic programming (LP-DP) methodology to the operation of Andong and Imha parallel reservoirs in South Korea. The model allows for multioptimization of power generation and municipal, industrial, and irrigation water use. It is shown that the annual average energy and the annual average water supply generated from the joint operation of the two parallel reservoirs by the LD-DP approach is 15.2 and 1.7% more than the contracted power production and water supply respectively.

做好水库移民工作 促进水电事业发展

《水电工程水库淹没处理规划设计规范》ＤＬ／Ｔ５０６４－１９９６经电力工业部批准发布实施了，它针对水电工程建设中有关水库淹没损失处理和移民安置规划设计工作的行为准则作出了规范。通过对新《规范》的学习，结合当前水电工程建设中存在的水库淹没损失的实物量指标变化大、移民安置方案定不死和水库补偿投资难以控制等难题，谈几点看法。     

State of the art of geothermal reservoir simulation

Computer modeling of geothermal systems has become a mature technology with application to more than 100 fields world-wide. Large complex three-dimensional models having computational meshes with more than 4000 blocks are now used routinely. Researchers continue to carry out fundamental research on modeling techniques and physical processes in geothermal systems. The new advances are adopted quickly by the geothermal industry and have also found application in related areas such as nuclear waste storage, environmental remediation and studies of the vadose (unsaturated) zone. The current state-of-practice, recent advances and emerging trends in geothermal reservoir simulation are reviewed.     

关于水库防洪调度若干问题的探讨

笔者在分析了水库实时防洪调度与设计阶段防洪调度的差别后，对在实时调度可以较大幅度地提高水库效益的两种主要措施──分期防洪调度，预报调度，在实施中应注意的问题作了探讨，分期防洪调度应注意摸清分期洪水的规律；正确划分分期时段，按规范的规定和方法计算分期设计洪水；依分期设计洪水拟定分期汛限水位。预报调度必须细致地编制预报调度方案，尽快建设自动测报系统。挖掘水库潜力关键是对来水尽早，尽准确的预知，由于不要
