IMPACT ASSESSMENT OF THE PROPOSED WATER RESOURCES DEVELOPMENT PROJECTS IN THE TEKEZE ATBARA SETIT BASIN ON NILE FLOW AT ASWAN

Abstract

Nile River is considered the primary renewable source of water to Egypt. Nile Basin could be divided into two main sub-basins. Eastern Nile sub-basin is the major one that contributes with about 85% of water inflows that arrives at Aswan. Tekeze Atbara Setit is one of the main tributaries of the Eastern Nile sub-basin that lies in Ethiopia and Sudan. Tekeze Atbara Setit is a target for many water resources development projects such as hydropower projects and irrigated agriculture. These projects may have negative impacts on downstream countries. This study introduces a hydrological model for Tekeze Atbara Setit to generate river system flows, which is then coupled with river and reservoir simulation model to simulate current flow conditions in addition to simulate different development scenarios in order to assess their impacts on High Aswan Dam.
