一个大的 被称为大埃塞俄比亚文艺复兴大坝(GERD)的大型水电站正在蓄水 在埃塞俄比亚-苏丹边境上游的青尼罗河上建造 在埃塞俄比亚。GERD的有效存储容量超过60,000 mm3，预计将产生6000兆瓦的水力发电。这样做的目的是 这项研究是为了评估大坝对性能的潜在影响 蓄水期和运行期高阿斯旺大坝的模拟 模型采用迈克盆地流域模拟模型。结果表明， 计划的6年灌水期足以用很少的水填满水库 埃及HAD对当前灌溉用水需求的影响 额外的管理投资。大约有12%和7%的降幅 阿斯旺高坝蓄水前后的年发电量 GERD分别处于充盈期。两种能源的累计发电量 大坝将显著增加因蒸发而造成的水损失 下降了22%。民政事务总署在填海期间及填海后的整体表现 GERD保持在96%的可靠性水平。这项研究建议利用 结果要谨慎，因为它只基于历史上对 未来可能演变的许多可能的情景。
A Large scale hydropower dam known as Grand Ethiopian Renaissance Dam (GERD) is under construction on the Blue Nile River just upstream of the Ethiopian-Sudan border in Ethiopia. The GERD has an active storage capacity of more than 60,000 Mm3 and is anticipated to produce 6000 MW of hydropower energy. The aim of this study was to assess the potential impact of the dam on the performance of the High Aswan Dam (HAD) during filling and operation phases using a simulation model using Mike Basin river basin simulation model. The results indicate the planned 6 years filling period is sufficient to fill the reservoir with little impact on the current irrigation water demands from HAD in Egypt without additional management investment. There will be about 12% and 7% of reduction of annual energy output from High Aswan Dam during the filling and after filling stage of GERD respectively. Cumulative Energy production from the two dams will increase significantly Water loss at HAD due to evaporation will decreases by 22%. Overall performance of HAD during and after filling of the GERD remains at a reliability level of 96%. The study advises to utilize the results cautiously as it is based on only one historical realization of the many possible scenarios that may evolve in the future.
