يتضمن البحث في المرحلة الأولى تقدير حجم الجريان السطحي و الترسبات المحمولة معه و الناتجة عن هطول الأمطار على جابيه نهر الخوصر الموسمي الواقعة شمال شرق مدينة الموصل/جمهورية العراق التي تبلغ مساحتها بحدود 725 كم 2. إذ إن هناك مقترحاً لإنشاء سد يهدف إلى حصاد مياه الجريان السطحي لأغراض الري التكميلي في المنطقة التي تستغل من خلال زراعتها بمحصول الحنطة و الشعير بشكل واسع. اعتُمَِد نموذج المناسيب الرقمية بغرض وصف طبوغرافية المنطقة و هي من العوامل الأساسية و المؤثرة في اتجاه حركة المياه و سرعتها. كذلك اعتُمَِدتِ البيانات اليومية للأمطار و درجات الحرارة العظمى و الصغرى للمدة بين عام 1989 و 2007 لمحطة الموصل، و ذلك بغرض تقدير حجم الجريان السطحي و الترسبات الناتجة عن كل عاصفة مطرية مؤثرة. يتضمن النموذج الذي طُبق كلاً من نظام المعلومات الجغرافية.
The paper includes in the first stage an estimate of the runoff volume and sediment load, resulting from rainfall on a watershed of Alkhoser seasonal river, north-eastern Mosul city/Republic of Iraq, which has an area of up to 725 km2. There is a proposal for construction of a rainwater harvesting dam for the supplementary irrigation in the region which is exploited by planting wheat and barley crop widely. Digital elevation model (DEM) was adopted in order to describe the topography of the region, which is one of the main factors affecting the water flow direction and velocity. It also adopted the daily data of rainfall, maximum and minimum temperature, for the period 1989 to 2007 for Mosul to estimate the volume of runoff and sediments resulting from each effective rainstorm. The applied model includes the Geographical Information System (GIS).

This study concentrates the use of remote sensing and geographic
information systems to identify prospective areas for water
harvesting, This study concentrates on the identification of the
potential areas for water harvesting projects in Hessia a
nd the
adjacent areas, within a total area of 1300 km2.
The data and information for the study area are collected from
different sources and satellite images. The thematic maps and
digital database were prepared through analysis and visual and
automatic interpretation of satellite images, and analysis and
intersections between different layers were procedure in order to
apply the criteria that are used in these studies to determine
optimal and typical sites for the establishment of preparation water
harvesting.
The result of this study shows the efficiency of using the remote
sensing techniques and the geographic information system in the
identification of the potential areas for water harvesting projects.
Clay mineralogy of the Miocene successions taken from northern Iraq
constitute an important paleoenvironmental indication for the evolution of
these sediments. Palygorskite is a common mineral especially in the lower
Miocene sediments of Euphrates
formation and the upper detrital part of the
Fat'ha Formation belonging to the middle Miocene. Scanning Electron
Microscope (SEM) study indicated that this mineral, was formed authigenically
by neoformation in suitable chemical conditions within the evaporitic
environments. Other minerals (kaoloinite and illite) have been most probable
formed in detrital system and were preserved in those evaporitic conditions.
Common kaolinites in the Injana clastic Formation (Upper Miocene) as well as
its habit in SEM images are indicators for its detrital origin in such continental
sediments.
The Alsafarqieh watershed is located on the western slopes of the coastal mountain range,
Its area is 132.58 km2, It forms a part of the Alros river basin, The river starts at a height of
1200 m, A group of tributaries meet and form the Alros River
, which flows into the
Mediterranean Sea. Salaheddin Dam was constructed to store 10 MCM on the riverbed at
the intersection of the Qurdaha River with the Shehada River. The study aims to determine
the rainfall- runoff relationship in The Alsafarqieh watershed. The solution depends on the
statistical analysis of precipitation and runoff data. Then the study found the mean annual
precipitation is 159.6 MCM/year, and the mean annual flow into the Salaheddin lake was
9.4 MCM during the study period (2010-2012), so the runoff coefficient is 0.06. This
indicates a significant water loss. A mathematical equation to predict the runoff quantities
depending on the values of precipitation, has been concluded. This is important to study
water projects for water storage and flood prevention.
Data on ١٦٠١ records over five years were used to study the reproductive
and productive performance of Awassi ewes kept at the animal husbandry
station (Darnajookh) in Iraq.
The overall means were ٨٠,٦٩±١,١٪, ١,٠٧٧±٠,٠٠٨, ٩٢,٨٢±٠,٨٣٪,
٠,٨٠٥±٠,٠١٤
, ١٨,٩٨±٠,٣٥ kg, ٥٣,٣٨±٠,٣٢ kg and ٢٢,٥١±٠,١٨ kg for
fertility, litter size, pre-weaning survival rate, number of lambs weaned per
ewe exposed to the rams, ewe productivity ( total weight of lambs weaned
per ewe exposed to the rams), body weight of ewe at breeding and weaning
weight of lambs, respectively.
The risk of soil erosion is the most important problem and challenges facing the agricultural process in the Syrian coast at the present time, especially in the areas surrounding rivers and water bodies.
