Abstract

Now days, the gap existence between the supply and demand water is the significant challenges in Egypt, so intensive efforts are being made to overcome the dilemma. Nile River is a key resource of Egypt, as it supplies by 97% of its all fresh water. Any change and development in the hydrology of Blue Nile Basin result in influences to natural inflow of Egypt, whereas Blue Nile is the biggest contributes of the River Nile supplies. For that reason Egypt’s concerns and fears regarding the implementation of dam and its filling stages have increased. The paper objective to evaluation process to current water budget of Egypt at period (2010-2026), then investigate the influence of GERD’s filling stages on Egypt’s water budget. The paper conducted based on geo-statistics data collection for Egypt’s water budget during the concerned period according to the annual reports to Ministry of Water Resources and Irrigation and Central Agency for Public Mobilization and Statistics. Results revealed that filling stages have negative impacts on water budget by decreasing especially in 2023 and 2024. It is recommended to apply reutilizing water through several appropriate approaches, reorganizing the distribution of water, and improve water transportations and eliminating its losses by lining irrigation canals and drainage canals, make evaporative condensers to utilize it, increasing abstraction of groundwater but take into account the necessary precautions.
