The geography and geology of south-eastern Egypt

For some eighteen kilometres south of the Wadi Khoda, the seaward
drainages have not been explored, but they are believed to be only
short wadis, as the high mountains of Faraid are here only about
ten kilometres from the coast. From guides’ statements, the =Wadi
Um Etli=, coursing eastward and draining the south faces of Gebel
Um Etli, enters the sea in about latitude 23° 38′, and there is
probably at least one other short wadi draining to the sea about in
latitude 23° 35′ from the north part of Gebel Faraid. The sandy
coast-plain in this region is about five kilometres wide.
The =Wadi el Sorubiab=, draining from the north part of Gebel Faraid,
and the =Wadi Bint el Kurdum=, draining the mountains around the
remarkable “Bodkin” peak, enter the sea together by way of a
small lagoon in latitude 23° 30′. Another wadi, for which I could
not obtain any name from my guides, drains the extreme south parts
of Gebel Faraid and the north slopes of the smaller Gebel Fereyid,
entering the sea in about latitude 23° 19′.
=Wadi Rahaba=, with a basin of about 900 square kilometres in area,
drains the country between Gebels Faraid and Abu Dahr. From its
head, situated about six kilometres south-east of Gebel Abu Dahr,
there is an easy pass into Wadi Salib el Azrak, a tributary of
Wadi Khoda. About three kilometres below its head, a feeder called
=Wadi Titai= enters Rahaba from the hill country to the east; and
a kilometre lower down, another feeder called =Wadi Abu Nikheil=,
comes in from the west. At this point there is an important well,
=Bir Rahaba=, sunk in the alluvium of the wadi floor; this is said
to yield good summer supplies, but was filled up by downwash when I
visited it early in 1907. Some three kilometres below Bir Rahaba,
a tributary called =Wadi Abu Reye= enters Wadi Rahaba from the
north-west; and there is said to be a well, called =Bir Abu Reye=,
about one and a half kilometres up this wadi. Another feeder, the
=Wadi Um Buerat=, joins Rahaba from the south-west a little further
on, and then the wadi, which has thus far taken a southerly course,
turns south-east, winding considerably for some eight kilometres
till it is joined by its most important feeder, the Wadi el Abiad.
This =Wadi el Abiad= drains the western side of the northern peaks of
Gebel Faraid, and derives its name from the white granitic sand which
forms its floor. It has a length of some twenty kilometres and is fed
by the =Rod Elbel=, which heads in a sandy plain at the foot of the
highest peak of Faraid, and by the =Wadi Abu Ribian=, which collects
the drainage from the lower hill country west of the Bodkin peak.
