The Upper Blue Nile River Basin is located in the northwestern part of Ethiopia between 7 0 45′ to 12 0 45′N and 34 0 05′to 39 0 45′E (Fig. 1).It drains an area of about 176,000 km 2 that covers about 17% of Ethiopia. The Blue Nile leaves Lake Tana and flows through a series of deep valleys and canyons and joins the White Nile at …
The aim of this article is to determine how human interventions in upstream countries coupled with drought events are affecting the flow regime of downstream countries using the Nile River basin for illustrative purposes. This has been addressed by assessing climate change in the study area through analyses of precipitation data …

Dispute remains unresolved between Egypt, Sudan and Ethiopia over a giant dam built by Ethiopia on the Blue Nile. Video Duration 24 minutes 40 seconds 24:40. Published On 4 Jul 2021 4 Jul 2021
The Grand Ethiopian Renaissance Dam (GERD), formerly known as the Millennium Dam, has been filling at a fast rate. This project has created issues for the Nile Basin countries of Egypt, Sudan, and Ethiopia. The filling of GERD has an impact on the Nile Basin hydrology and specifically the water storages (lakes/reservoirs) and flow downstream. In this study, …
The period (1983–1994) was more altered than 1995–2016. This shows that Isapur dam has higher impact on flow regime change than Arunavati dam. Information about alteration of hydrological parameters will be helpful to improve the water flow regulation at Isapur and Arunavati dams for restoring river ecology on the downstream …
Abstract. Climate change scenarios of precipitation and temperature were divided into three time windows of 30 years each from 2011 to 2099. The new version of Soil and Water Assessment Tool (QSWAT v2.6.1) was used to simulate the hydrological response and it was first calibrated and validated using observed data as an input for …

Studies are urgently needed to identify the magnitude of these potential problems, and to mitigate their impact. Managing the flow. Perhaps the biggest question concerning the new dam is how Ethiopia will manage the process of filling its huge reservoir, whose capacity equals more than a year's flow of the Blue Nile.
