Question

where is water available in sahara why is sahara called desert

Answer 1

Answer:

Although water is scarce across the entire region, the Sahara contains two permanent rivers (the Nile and the Niger), at least 20 seasonal lakes and huge aquifers, which are the primary sources of water in the more than 90 major desert oases.

The word ṣaḥrāʾ shares its roots with the Arabic word aṣḥar, which translates to “desert-like” and specifically connotes the yellowish red color that characterizes the Sahara's sandy expanses.
