بينت الدراسة الإحصائية للشقوق في منطقة بحيرة 16 تشرين في حوض نهر الكبير الشمالي وجود عدة مجموعات رئيسة للشقوق ذات اتجاهات NE-SW إلىNNE-SSW، و NW-SE، و E-W. أظهرت المجموعة NE-SW توافقاً مع بنيات الصدوع من نفس الاتجاه و هي صدوع عادية و عكسية، تتوزع جغرافياً في نطاق صدع اللاذقية كلس، و تبدي أيضاً توافقاً مع محاور الطيات من نفس الاتجاه و بذلك تفسر على أنها شقوق طولية في هذه الطيات. كما أظهرت المجموعة NW-SE توافقاً مع بنيات الصدوع من نفس الاتجاه و هي صدوع إزاحية جانبية يمينية و يسارية تنتشر على كامل منطقة الدراسة و قد تشكل جملاً قصية (قطرية) في طيات ذات محاور NE-SW. كما أظهرت المجموعة E-W توافقاً مع بنيات الصدوع العادية.
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 fault 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.

Thousands of dams have been built around the world, but, the date of construction is
associated with a history of failures and collapse, due to the high water levels, generating
higher returns consequences disastrous for the environment and society
, when dam fails
released very large amounts of water threatened the lives of persons and property, it
returns to the short time available for warning and evacuation.
This paper provides an overview of the most important reasons for the collapse, with
a study about possibility failure product from supposed breach in 16 Tishreen dam, caused
by the flow of water over the top, where the predicted of breach that leading to collapse is
done and determine its characteristics, namely: High, width, time required to development
of the breach, the maximum flow out of it, and also generate flood maps that represent the
limits of the spread of flood wave downstream, in addition tosuggest a simplified plan for
the evacuation
Results led to the flooded wave caused by the collapsehurtling loaded
adischargeabout 54631 , causes a wall of water with 17 meters high moves
through the downstream river with 14 m/sec speed, the wave spreadover 45.24
,causing submerge for 7 villages the most important of it Stkhers and Rodo which are
completely submerged, and 30 economical facility the most important of it industrial area
that also completely submerged, the water depths ranged from 2 to 17 meter, which
causing heavy casualtiesand damage about 30000 people, and more than 7000peopleare
expected to die, unless the actual preparations of emergency plan.
This study aimed at determining the fish fauna composition in 16th of Tishreen Lake
(Alkabeer Alshimali River). A total of 730 individual fishes were collected between April
2012 and March 2013 from five different sites along the lake /Alsafkoon, W
ata-Alsheer,
Alkerassat, Mazraet Alsheikh Deeb, and Alaqfaas area/.
Our results showed the presence of only six main fish species belonging to three
families (Tillapia zillii, Cyprinus carpio, Liza abu,Varicorhinus damascinus, Garra rufa
and Garra lamta). The results also showed that Tilapia zillii was the most caught fish, and
Wata-Alsheer was the richest site in the lake. These results showed a decrease in the
number of fish species and their quantities compared to that in previous studies on the lake.
Study of the general characteristics of Fractures in the central part of
the AL-Kabir AL- Shimali river basin showed the presence of
several main groups of Fractures with directions NE-SW _ NNESSW,
NW-SE , E-W.and showed increased fracture rate in
the
northern and southern parts of the study area, and that the spacing
between the Fractures close to the medium convergence (5-34) cm ,
also show a aperture ranged between (0.1-5.1) cm, where aperture
width was increased in southwest of Lake 16 October near Lattakia-
Kless fault .
The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve
this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake
water. The samples were taken at five sites
along the lake for a period of one complete year. The indicators
that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C.
Measurement results were represented diagrammatically, and compared with the Syrian Specification
Standards for portable Water. The lake was classed according to these Indices: Malays quality index,
Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following:
from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade
to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this
indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined.
The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other
locations.
