أعطت نتائج البحث الذي اعتمد على التحريات الهدروجيولوجية و التكتونية، المرتبطة بمصادر المياه العذبة في حوض السن، أن الحامل الأساس للمياه الجوفية في حوض السن يعود بشكل رئيسٍ إلى الحامل المائي الجوراسي. يعتمد الحوض الصباب لنبع السن على التغذية الراشحة لمياه الأمطار و الثلوج عبر التشكيلات الجوراسية من المنطقة الشمالية و الشمالية الشرقية للحوض. إن اتجاه حركة المياه الجوفية لهذا الحامل يكون نحو الغرب و الجنوب الغربي، حيث منطقة التصريف في نبع السن و الينابيع تحت البحرية قبالة الشاطئ. بينت الدراسة التكتونية وجود مجموعات من الشقوق و الفوالق ذات الاتجاهات NE-SW و ENE-WSW و NW-SE. تتوافق حركة المياه الجوفية مع اتجاهات مجموعات الشقوق و الفوالق NE-SW و ENE-WSW و بنية فالق السن الذي يسمح بوجود علاقة تفاعلية بين الحامل المائي الرئيسي الجوراسي و بقية الحوامل الثانوية و خصوصا السينوماني.
The obtained results by hydrogeological and Tectonic survey related to fresh water resources in Al-Sin Basin, indicated that the fundamental aquifer of underground water in AL-SIN region belong to Jurassic. The alimentary basin of Al-Sin spring depend upon filtration of rainfall water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation is toward west and south-west where we find flow place of Al-Sin spring and submarine fresh springs near seashore. Tectonical study shows the existence of fractures and fault groups with NE-SW, ENE-WSW and NW-SE directions. Groundwater movement has the same direction of fractures and faults NE-SW to ENE-WSW and Al-Sin fault structure which allow the existence of direct relation between principal Jurassic aquifer and secondary aquifer especially Cenomanian one.

Tectonic study and structural analyses of Al-Sin Faults Zone show
that it is composed from a group of E-W to NE-SW pure normal
faults, characterizing by increasing of vertical throw from east to
west. Formation and evolution of Al-Sin Faults Zone
principally
related to coastal Range uplift during Levant Fault formation in
lower Pliocene. Al-Sin Faults Zone used heritable faults from lower
Cretaceous, witch interpret the important deviation of its direction
from E-W to NE-SW.
The importance of this study lies in the hydrological analysis of the
relationship between the drainage system and the precipitation. The
problem of the study reveals in the water incompetence in the basin
which get to 336 million m3 and will gets
to 600 million m3 with
probability (p = 50%) and associated with missing the accurate evaluation
of the water resources.
The study aims to evaluate the water resources in the basin, to create a
mathematical model for calculation of the run off and its relationship with
the precipitation, and to predict the water resources for the hydrological
year according to many probabilities and the complementary
management for water resources.
Stages of the study involve the following:
1- Determining of the active stations in the feeding of hydrometric
stations.
2- Observing the average of water resources quantity (precipitation) over
the basin that reached 9764 million m3 and range between 2,26millionm3 in the hydrometric station of AL- Hamidi and 112,42
million m3 in Hama station.
3- Observing the average of the run off in the basin reached 744,67542
million m3.
4- Observing the run off system in the basin is a snow-rain system, where
the average of maximum discharge associates with precipitation and the
minor discharge associates with deprivation of the precipitation.
5- Creating a mathematical model for calculation of the run off and its
relationship with the precipitation.
6- Predicting the water resources for the hydrological year according to
many probabilities.
7- Creating a water strategy for the basin according to the data of water
predication in many probabilities
The aim of this research is to identified the tectonic evolution of
Naher Al-Kabir Al-Shimaly Basin from tectonic subsidence curve
witch calculated from Lattakia1 well data. Tectonic subsidence
was identified in lower-middle Jurassic en relation o
f opening of
East Mediterranean basin. A subsidence is occurred in
Cenomaniane, after a stage of uplift in late Jurassic-lower
Cretaceous en relation to fold and erosion known at regional
scale.
River flows depend on precipitation in their catchments, where the flow is highly
correlated with precipitation, among many climatic and geographic factors. The
relationship between precipitation and runoff is of great importance in estimating flow
changes in The HWAIZ basin that is located between The-Zrod and The-Gelani basins.
The Al-HWAIZ Dam was built on the HWAIZ River with storage capacity of 16.5 MCM.
The purpose of this study is to find a relationship between rainfall and runoff in The
HWAIZ basin. This study depended on statistical analysis of rainfall and runoff data, and
the analytical study of the annual rainfall data (1959-2011), to guess the trend of rainfall
and its future changes and forecasting changes in the HWAIZ river flows. The study
showed that the runoff coefficient values ranged between (0.007-0.66). A mathematical
relationship was established that allows to estimate flow based on measured or predicted
precipitation values, as well as appraise missing or lacking data with accepted level of
accuracy.
Results of this research which had been done by hydrogeological and geoelectrical survey for fresh water resources in the study region (wells and springs) show that the fundamental aquifer of underground water in AL-SIN region belongs to Jurassic. Th
e alimentary basin of AL-SIN spring depend upon filtration of rain water and snow throw Jurassic formation from north and north–east of basin. Direction of underground water circulation on west and south-west where we find flow place of AL-SIN spring and submarine springs near seashore.
