Changes in Floods
For thousands of years Egypt has relied on the flooding of the Nile River to help them grow their crops and as Egypt is primarily desert, floods are actually good for humans, plants, and the relative ecosystem in general. The Nile River always floods in June, September and October with October having it's highest river level.
Changes in Agricultural Production
Each time the Nile floods agricultural production always goes up, with the major floods in October being the most productive. This happens because each time the Nile River floods it washes important nutrients to the plants in this region that have long been deprived of the necessary nutrients that they require for full growth.
