流域设计枯水流量分析计算方法
|
摘要
流域枯水流量的大小,主要依赖于流域蓄水量的补给;同时随着流域蓄水量的减少,枯水流量也不断衰减。流域枯水流量与河道通航、城乡供水、水电厂与火电厂设计(运行)和生态环境质量等密切相关。流域枯水流量虽不如洪涝和地震等自然灾害与人类的关系那么剧烈,但它可严重制约工农业生产的发展和人类生活质量的提高。本文详细介绍了流域设计枯水流量分析计算涵盖的枯水调查与资料收集、枯水流量资料的审查与处理、具有实测资料时设计枯水流量的计算、资料不足时设计枯水流量的估算、缺乏资料时设计枯水流量的确定以及设计枯水流量成果的分析论证等6部分内容,以供从事河道航运、城乡供水和环境保护等部门工程技术人员参考,以利于经济社会更好地发展。
The amount watershed low flow mainly depends on the volume of recharge of watershed storage capacity;and with the reduction of water storage,low flow continuously attenuates.Watershed low flow is closely related to water transport,urban and rural water supply,hydropower and thermal power plant design and operation as well as eco-environmental quality.Although watershed low flow is not more significant than other disasters such as floods and earthquakes for human,it could severely restrict the industrial and agricultural development and improving the quality of human life.This paper described in detail that six parts of analysis and calculation of watershed design low flow,including the low flow survey and data collection,data examination and processing,the calculation of design low flow with the observed data,the estimate of design low flow without adequate information or data and the results analysis of design low flow etc.,It appears both practicable and feasible for engineers and technicians on water transport,urban and rural water supply,hydropower and thermal power plant design and operation as well as environmental protection,in order to facilitate better social-economic development.
