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.
SST satellite images analysis has provided us a new description of the surface
circulation in the eastern basin of the Mediterranean Sea. It showed many characteristics
for a lot of mesoscale eddies. In this study, the SST analysis is focalised on
the upwelling
structure showing by images, in the eastern basin of the Mediterranean Sea, which has an
important biological reflection at the marine environment. We have analyzed images for
different periods to identifier this phenomena's places and this will be help us in situ
nutrient observations.
This study aims to monitor the soil content of iron oxides, mechanical composition, organic matter and calcium carbonate, then mapping the distribution and percentage of the studied element within the Akkar Plain, south of Tartous Governorate, using
images of the artifact (Rapideye). The soil in the study area
Specialists use many methods to achieve their aimes .These methods help to detect
and correct errors ,in addition to identifying and addressing the weaknesses ,or to add more
effective tools and aids in order to develop the performance .
The kinet
ic analysis methods adopted by the biomechanics are considered one of the
best and most effective methods which help detecting the errors associated with the
performance through evaluating the variables representing the performance specifications.
This study focuses on the determining the values of the pelvis speed , and stretched
bow speed as variables and the speed of Javelin launching and studying the relation
between them. This study applied on five Syrian Javelin throwers from the national team
who participated in Arab and Asian championships.
The study concluded that there was a significant correlation between the speed of
pelvis and the launching speed , and there was no significant correlation between the speed
of stretched bow and the launching speed neither between the speed of pelvis and the speed
of stretched bow. In additionto the low level of the javelin speed lower than world
champion's level .There is a weakness in the using of the kinetic transport and in taking
advantage from the forces resulting from approach .
Banias River Basin is located in the middle of the Syrian coast between the Joubar and
Merqiah River Basins. Its catchment area is ) 97 ( km2, and its length is ( 24,5) km.
The research aims to get the optimal management of the available and non-ex
ploited water
resources of Banias Spring, using water evaluation and planning system WEAP. Research
methodology based on collecting data and proposing two scenarios, first: storing of Banias spring
water to provide the water requirement of Banias city, Second: replacing Sin Spring in order to
provide Banias Refinery water. The percentage of coverage is about 88% requirement in scenario
of water supply to Banias city, while differentiated during the year in scenario meet the water
requirement of Banias Refinery, which has reached 84% in the first six months and fallen in
October to 52%. Existing wells in the confined aquifer are used to cover the shortfall in the
requirement.
The "Middle East" is one of the most tense regions of the world, and these tensions linked mainly to the existence of the Zionist entity as an outside intity cruel implanted in the heart of the region, and which seeks to exploit and steal any land a
nd wealth lies in his hands.
And with the discoveries of reserves the vast gas and oil in the levant basin escalated tensions in the region after Israeli efforts to exploit these reserves and stealing these resourses without taking and this led to the outbreak of differences bilateral and multilateral conflicts of interests among the countries in the region which allows Israel to play a key role in these issues, especially the Lebanese – Israeli conflict ,the Turkish – Cyprios case which Israel is third party in such conflicts.
International river basins are characterized by their wide extent where mapping earth
surface features and drawing contours by topographic team become–somehow- impossible
because the cost and efforts consumed to execute it become very high and may
exceed
reasonable limits. Here it becomes necessary to use digital elevation models (DEM)
inferred by specialized scientific organizations using remote sensing.
There are several DEMs available on the internet and downloadable for free. The
primary factor in defining the models efficiency in building hydrological models not the
least cost but the maximum reliable results and better resolution that adequate to the
capabilities of the PCs.
In this study, three DEMs were used to derive and build hydrological models for the
Euphrates-Tigris basin using Geographic information system techniques. The resulted
boundaries of Euphrates-Tigris basin were compared with three boundaries implemented
by international research organizations (UNEP, ESCWA, and FAO). As a conclusion of
this comparison, the SRTM—3arc DEM was the most efficient model among used models.
In addition, this study indicated the necessity to reevaluate Basin’s boundaries and correct
the spatial distribution of proportion for basin area between the riparian countries.
Al-Kabeer Al-Shemale river rises from Aqraa Mountain and coastal mountains, it is considered one of the largest rivers in the coastal area.Its catchment area is 1097 km2, and empties into the sea to the southern of Lattakia.The study aims to determin
e the impact of climate change on the river discharge. Since the rainfall is the major factor in the runoff formation in the river catchment, the rainfall changes have been studied in climatic stations located within the catchment and its surroundings, and for a period of time exceeding thirty years. The study found that the general trend of rainfall change and runoff with time is decreasing, declining rainfall values ranged in the studied stations between (0.4-12.5) mm per year, and the runoff reached 0.08m3/s in the year. A mathematical equation, predict river discharge after knowing the values of daily precipitation, has been concluded.

In this paper we present the preparation of PbS nanocrystalline thin films
using Chemical Bath Deposition (CBD) technique. We have performed this
work in order to study the photoconductivity of PbS semi-conductor thin films.
The details of the pre
paration method are described. Thickness of deposited
films has been determined using mechanical and optical methods. From the
optical absorption measurements we have determined the band gap values.
Using the first approximation parabolic bands model and the obtained values
of band gaps, we have determined the size of PbS nanocrystallites. Also, we
have investigated the electrical and photoelectrical behaviors of the PbS films.
Our study shows that the size of PbS thin films nanocrystallites affects the
photoconductive properties of the material. Furthermore, investigations show
that there are two different sizes of grains located in two different layers, the
first one, with grain’s size of about 25nm, concerns the part of PbS deposited
directly on the glass substrate and the second layer, with grain’s size of about
70nm, concerns the PbS deposited on the first layer.
