The results of the research show: When distributing the quantities of traditional water resources in the Nile Basin countries according to the source, the amount of surface water amounted to about 1774.4 billion m3 in 2019, and the Democratic Republic of the Congo, Ethiopia and Tanzania occupy the first three ranks in the Nile Basin countries, which It amounts to about 1283, 122 and 96.27 billion m3, with an estimated rate of 72.31%, 6.88%, 5.43% of the total amount of surface water in order, and by estimating the dependency ratio for all the Nile Basin countries, it was found that Egypt, Sudan and South Sudan The Nile Basin country is the most dependent on external renewable surface water, and this percentage was estimated at about 98.26%, 89.42%, and 47.47% of the total renewable surface water, respectively.

The results show that the rate of water pressure for the total available water resources in Egypt reached 96,689% during the period (2004-2019), and by estimating the equation of the general temporal trend of the rate of water pressure during the same period, Table (5) shows that it took an increasing general trend.

Its significance is statistically proven.

By studying the distribution of the relative importance of using the available water resources in Egypt as an average for the period (2004-2019), the agriculture sector occupied the first place with about 61.00 billion m3, with a rate estimated at about 81.81% of the total user and consuming about 74.64 billion m3, followed by the water sector Drinking, household use, water losses and evaporation, and the industrial sector, with an estimated rate of 11.93%, 3.13%, and 2.24 of the total water resources used respectively.

By studying the degree of water poverty during the same period, the results indicated that Egypt entered the stage of water poverty, and it will reach its maximum in 2029 by about 510.64 m 3 person / year, then Egypt enters the stage of water scarcity, which will reach its maximum in 2049 at about 371.41 m 3 person / year.
