In the Nubian section of the Nile, the river is characterized by numerous rock-filled rapids, commonly referred to as "cataracts." These cataracts create challenging navigation conditions and contribute to the river's dramatic landscape. The most notable of these is the First Cataract near Aswan, which historically marked the southern boundary of ancient Egypt. The presence of these rapids has played a significant role in the region's history and trade routes.

This is impossible to answer due to the issue of hydrodynamics. Rapids are constantly being gained and lost due to the action of the water's movement (erosion). Also, the rainy season would cause some of the smaller rapids to be covered.
Two of the many problems of life along the Nile river include 1) water pollution, and 2) schistosomiasis (infection). There are many more problems, as well.
