No. [And I didn't include the western Egyptian desert in the "near
east" as it's part of the Sahara belt]

The road is a path between daily pit stops, not a path for taking a
sip every hour. Such roads will typically use plateaus for easy
traveling, and water sources will typically be in the lower points of
an area. You can have a well or a spring 100 meters/yards from the
road and not see it because it's in a wadi or canyon.
From Eilat/Taba to Thamad is a day's walk. From Thamad to Nakhl is a
day's walk. Etc. Let's see ... here:
"Located in central Sinai, Nikhel has a historical and strategic
location on the juncture or main roads to Suez, al-Areesh and South
Sinai as well as the old pilgrim road. Nikhel also lies on the
International Highway which passes through al-shaheed Ahmad Helmi's
Tunnel and proceeds past Nikhel towards the sea outlets such as
Nwaiba' and air and land outlets such as Ras an-Naqab and Taba.
Nikhel covers an area of 11,034 square km. and hasa population of
about 7,500 (as at 1998), distributed over 10 villages and 49
hamlets. Citrus and vegetables are grown on well water in small
plantations at al- Khafaja, Beer Jareed, at-Tamad and al-Kontella,
while wheat and barley are grown on rain water. Vast areas in the
eastern parts are known for natural (unattended) plants growing on rain water."
>One was able to walk 24 miles in a day.
25 miles per day (~40 km) is a slow pace - rough terrain, extreme
heat, etc. 35 miles should be more like it for average (desert)
conditions and over 40 miles per day for forced march. Livestock is
slower, of course, but it can handle morning to next-day's evening
treks (and so can people). And moving herds of livestock between
water sources that are far apart is done twice a year, if at all.

Of course - that's why these areas are "desert"-ed. They are not
hospitable. But some deserts are unpopulated while others are
under-populated, and most of the NE ones are under-populated, not
Most desert wells draw from underground aquifers and don't depend on
rainfall to the point of being affected by a few years of draught.
See what the Saudi's did in the Al Jawf area with underground water
(you can actually see it from space, in satellite images). Long
stretches of draught (in the areas which feed the underground
aquifer) will of course affect the water table and the water level in
those wells, and this will in turn affect the people who live off
these wells. And if these long stretches of draught become frequent,
the climate is changing and the population patterns will change with it too.
There's a huge amount of research on the hydrology and water
resources of the arid areas in the NE. Some of it also addresses the
hydrological history of these areas.
