Joints study in Skhaba region shows the existence two joint directions, principal dominant NW-SE Joints from extension origin upper Cretaceous age, unrelated and older than faults in studied area statistically, the presence of Calcareous filling in the joints that is supported the extension origin in the first phase. Secondary NE-SW joints from Miocen-Pliocen in age, and from extension origin ,related to the formation of faults, most of them contain thin iron crust in secondary phase.

Research summary
تتناول الدراسة تحليل منظومة الشقوق في منطقة سد السخابة بشمال غرب سوريا، حيث تم تحديد اتجاهين رئيسيين للشقوق: الاتجاه الأول NW-SE وهو ذو منشأ شدي من عمر الكريتاسي الأعلى، والاتجاه الثاني NE-SW من عمر الميوسين-البليوسين. تم إجراء قياسات ميدانية مكثفة باستخدام البوصلة الجيولوجية لدراسة الوضعية الفراغية للشقوق في 90 محطة قياس موزعة على امتداد المنطقة. أظهرت النتائج أن الشقوق ذات الاتجاه NW-SE لا ترتبط بالصدوع الموجودة في المنطقة، بينما الشقوق ذات الاتجاه NE-SW تتوافق مع الاتجاه الرئيسي للصدوع. تم تفسير منشأ الشقوق في إطار البنية التكتونية للمنطقة، حيث تشكلت الشقوق NW-SE في مرحلة تكتونية أقدم من الصدوع، بينما تشكلت الشقوق NE-SW في مرحلة تكتونية أحدث. توصي الدراسة بإجراء قياسات دقيقة للحشوات الكالسيتية ودراسة التكتونيك الحديث والنشط في المنطقة.
Critical review
تعتبر الدراسة شاملة ومفصلة في تحليلها لمنظومة الشقوق في منطقة سد السخابة، حيث اعتمدت على بيانات ميدانية دقيقة وتحليل إحصائي متقدم. ومع ذلك، يمكن الإشارة إلى بعض النقاط التي قد تحتاج إلى مزيد من التوضيح. على سبيل المثال، لم يتم توضيح كيفية تأثير الشقوق على استقرار السد بشكل كافٍ، كما أن الدراسة لم تتناول بشكل مفصل تأثير النشاط الزلزالي الحديث على الشقوق والصدوع في المنطقة. بالإضافة إلى ذلك، قد يكون من المفيد تضمين المزيد من البيانات حول التغيرات المناخية وتأثيرها على حركة المياه الجوفية وتسرب المياه من السد.

The statistical Study of Jointsarround 16 Tishreen lake dame region in ALKabir ALShimali river basin showed the presence of several main groups of Joints with directions NE-SW _ NNE-SSW, NW-SE, E-W. - Group NE-SW: showed correspond to with the fau lt structures of same directions which are normal and reversal faults and distributing geographically 1n Lattakia Kallas fault zone. Also it showes correspond to with the axis of folds of same direction, thus explained as longitudinal joints within these folds - Group NW-SE: showed correspond to with faults structures of same direction. which are left and right lateral strike slip faults, Spread over the entire study area. and it may(diagonal)shear group within the folds of NE-SW axes. - Group E-W:correspond to with normal faults structures.
The study of fracture in Kadmous and Safita showed several fracturing directions, originally related to the tectonic structure of the studied zone, especially faults. A group of dominant principal fractures, with a direction of NW-SE, a group of less importance with direction of NE-SW, and a secondary group of N-S direction, have been determined.
This search shows the lithological, petrographical and physical properties of the dam, and storage basin through rocks cors study taken from some wells in axis dam and storage lake and surface samples therefore have shaped unpenetration and penetra tion units. From this study discern reduction degree pored with rise positions deep far from range movement underground water and observed attachment pored grade cracs, Faults and karstic, Karstic discerned in positions (campanian, turounian) Increase Karstic caves in sinomanian positions from during tectonic cracs and naught being it in mastrichtian also action space in area dry weathering above level underground water because movement water across this cracs and vacuity.

This research aims to study the distribution of Phytoplankton in four locations which have different environmental specifications, in addition to study some environmental factors of Alhaffeh Dam water that affect the distribution of the phytoplankt on (Temperature ,BOD, DO, pH, NO3, NO2, NH4, PO4). Samples were collected from different locations of the Dam basin from June 2011 to May 2012 once or twice a month. (84) species of Phytoplankton were identified and were distributed as: (38) species of Chrysophyta, (36) species of Diatomophyceae, (2) species of Chrysophycea, (25) species of Chlorophyta, (20) species of Cyanophyta, (2) species of Pyrrhophyta, and (5) species of Euglenophyta. The results show apparent changes in physical and chemical properties of water during this study. This is the first study of the phytoplankton on the water of Alhaffeh Dam.
This study was achieved through Mars 2011 until February 2012 the samples collected monthly from Baksa dam from different four location which differenced each other with chemical and physical qualities. We could in these study classified 132 speci es of phytoplankton distributed as 59 species belong to chrysophyta, 40 species of chlorophyta and 28 species of cyanophyta , 5 species of Euglenophyta. Physical and chemicalanalyzing ofBaksa waters showed the difference of values between studding regions, The concentration of Nitrate ions ranged between 17.7 mg/l at third location and 0.3 mg/l at second location, The highest rate to Phosphate ions was 18.8 mg/l and the less was 0.01mg/l, and it was noticed the difference in these values in the same region with the difference of period of time. The diversity and distribution of studied phytoplankton correlated with the environmental factors. It was noticed The abundance of cyanophytain the water of third location which near to the sewage channels which is suitable environment to these group of phytoplankton.
