引汉济渭工程水资源论证

Water resources assessment on water diversion project from Hanjiang River to Weihe River

跨流域调水工程因调水量大、涉及范围广,其水资源论证具有一定的难度和复杂性。以引汉济渭工程为例,探索跨流域调水工程水资源论证的方法。根据引汉济渭调水工程的特点和建设项目水资源论证导则,结合该项目的取退水方案,合理确定了水资源论证等级,分析了取水所产生的影响,并提出了引汉济渭工程取水水源论证结论。结论表明,引汉济渭工程近期水平年从汉江多年平均调水10亿m3基本可行。该结论为引汉济渭工程水资源论证报告书采用,为项目获得取水许可提供了依据,对跨流域调水工程的水资源论证具有一定借鉴意义。

The inter- basin water diversion is characterized as large water diversion amount and wide involvement range,so the water resources assessment is difficult and complicated. The water resources assessment method was explored by taking water diversion project from Hanjiang River to Weihe River as an example. According to the characteristics of this project and guideline of water resources assessment of the constructed projects,by considering the water intake and discharge scheme,the level of water resources assessment was determined and the influence caused by water intake was analyzed,based on which the conclusion of the water resources assessment was put forward. The results showed that the annual average water diversion amount of 1 billion m3 in immediate level year is feasible. The conclusion was applied in the report of water resources assessment of water diversion project from Hanjiang River to Weihe River,which provided basis for approval of water intake license acquisition.
