Abstract

Study region

The Tekeze-Atbara-Setit (TAS) basin as a portion of the Eastern Nile Basin (ENB) in Africa.

Study focus

ENB consists of four sub-basins; one of them is the Tekeze-Atbara-Setit basin. TAS basin is subject to future water development projects, including irrigation projects and hydropower dams. Potential impacts of these projects need to be assessed regarding the inflow and hydroelectric generation at Egypt's High Aswan Dam (HAD).

New hydrological insights for the region

Two models are coupled offline; The Soil Water Assessment Tool (SWAT) model and HEC-Reservoir Simulation Model (HEC-ResSim). Base-case scenario is created without the expected future projects, in addition to five additional scenarios representing hydropower and irrigation projects. The maximum annual inflow at HAD declines by 1.6 km³ in the hydropower scenarios, while the produced power at HAD descends by 9.5 %. The maximum reduction in the annual inflow for hydropower and irrigation projects scenario at HAD is 4.63 km³ and 35.2 % for power reduction. Finally, the proposed future development project in TAS basin will have negative impacts on the flow, and generated hydropower at HAD in Egypt.

评估 Tekeze-Atbara-Setit 流域未来水利开发项目对埃及阿斯旺尼罗河流入量的影响

研究区域特克泽-阿特巴拉-塞蒂特流域（TAS）是非洲东尼罗河流域（ENB）的一部分。研究重点ENB 由四个子流域组成，特克泽-阿特巴拉-塞蒂特流域是其中之一。特克泽-阿特巴拉-塞蒂特流域未来将开展水利开发项目，包括灌溉项目和水电大坝。需要评估这些项目对埃及阿斯旺高坝 (HAD) 的流入量和水力发电量的潜在影响。对该地区的新水文见解离线耦合了两个模型：土壤水评估工具 (SWAT) 模型和 HEC 水库模拟模型 (HEC-ResSim)。除了代表水力发电和灌溉项目的另外五个方案外，还创建了没有预期未来项目的基础方案。在水力发电方案中，哈拉哈河断面（HAD）的最大年入库流量减少了 1.6 千立方米，而哈拉哈河断面（HAD）的发电量减少了 9.5%。在水电和灌溉工程方案中，哈德河的年最大入河水量减少了 4.63 千立方米，发电量减少了 35.2%。最后，拟议的 TAS 流域未来开发项目将对埃及 HAD 的流量和水力发电量产生负面影响。
