Mosul Division
(1) South of Mosul between the Tigris and the hills of Jabal Maglub, Bashiqah and Safrah.
(2) Between the three hills mentioned above and the Aqra Dagh. The structure is an
irregular basin and it is possible that artesian water may be found in this locality.
(3) The plain lying to the south of Tal ‘Afar and the Jabal Sinjar. A number of old
“ Kareze ” are said to exist in the plain ; therefore it is likely that water will be found
at a shallow depth.
(4) A small area between Jabal Sinn Mishraq and Qaiyarah. This is a semi-basin and might
be worth testing.
(5) Between Qaiyarah and Huwaish.
(6) Between Huwaish and Sharqat.
(7) The valley between Jabal Khanuqah and Jabal Makhul.
The country from Jabal Sinn Mishraq along the west bank of the Tigris must be considered as
unfavourable because the Lower Pars beds cover the whole area and are in general anticlinal.
There is certainly water in some places, but boring here cannot be recommended.
Arbil Division.
In this division there is a large area in which the conditions favourable for artesian water are
fulfilled.
(8) & (9) The Arbil Plain, which lies between the Greater and Lesser Zab Rivers, extends
from the Avanah Dagh to the foot of the mountainous country to the east. Bakhtiari
beds form a syncline the east flank of which is the gravel and conglomerate hills at
the foot of the mountains. The west flank is the Avanah Dagh. To the north-west
the syncline is closed by the uplift of Jabal Maglub whilst to the south the Bakhtiari
gravels close round and form the broken hilly country from Altun Kupri to Chem-
chemal. The Arbil plain is, therefore, approximately a basin.
The collecting ground for water is chiefly in the gravel and conglomerate hills to the north and
east and to a lesser extent in the Avanah Dagh. The rainfall to the north-east appears to be
considerable as clouds break on the Bakhtiari hills before they reach the mountains. A large
quantity of water should sink into the porous beds of the formation and will be held up by the
impervious marls which are inter-bedded with the conglomerates and gravels.
The conditions for artestian water seem to be good here and area 9 is recommended for a test
bering. The depth at which water wiil be struck should not be very great and a number of water
boaring beds each separated b> an impervious layer, may be expected.
^ me there are may Kareze ” in the plain ; they consist of one or more wells of
depth from a tevv feet to about 100 feet and are connected by an underground channel from which
strong streams of water flow. They must be considered as artesian wells and are a favourable
indication of what may be expected by deep boring.

of Lpper Pars beds. A hmited area between Dibega and the foot of the Qarah
Fn ^ Ug , P agh be worth a test. The collecting area is limited because the
Pars beds are highly inclined on the flanks of the syncline. No evidence is
obtainable in the flat alluvial plain of the Tigris to the west of the Qarah Chaugh
Dagh but Upper Pais and Bakhtiari beds probably underlie the alluvium. Areas 4 & 5
extend into the Arbil Division
Kirkuk Division.

Both these areas are synclinal and might be worth a test.
