تكتسب السدود في المناطق الساحلية أهمية كبيرة نظراً لاستخدامها في الري بشكل أساسي إضافة إلى استخدامها كمصدر من مصادر مياه الشرب في بعض الحالات. يهدف البحث إلى دراسة بعض المؤشرات الكيميائية لجودة مياه بعض السدود في محافظة اللاذقية على مدى العشر سنوات الأخيرة، شمل البحث دراسة تراكيز شوارد كل من الكلور، و الكبريتات، و النترات، و النتريت، و الفوسفات، و الصوديوم و البوتاسيوم في خمسة سدود موزعة على امتداد ساحل محافظة اللاذقية، و هي سد بللوران، سد 16 تشرين، سد الثورة، سد صلاح الدين (السفرقية) و سد الحويز. أظهرت النتائج حدوث تغيرات مهمة في تراكيز معظم الشوارد خلال السنوات العشر الأخيرة، حيث بينت النتائج ارتفاع في تراكيز الشوارد في معظم السدود المدروسة، و لكن في الوقت نفسه هذا التغير ليس واحداً في جميع السدود بل كان يرتبط ارتباطاً وثيقاً بطبيعة السد و موقعه و سعته التخزينية.
The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The concentrations of ions (Cl-1, SO4-2, NO2-1, NO3-1, PO4-3, K+1, Na+1) in five dams (Balloran, 16 Tishreen, Al-thawra, Alsafarkia and Alhweez) were studied. The results indicated that most of the ions showed significant difference in concentrations during 2002-2011.The ions concentrations in most studied dams increased. The increase related to characteristics of dams (location, capacity, the activities located around the dam…).

This study aimed at determining some indicators of water quality in Lattakia dams within ten years (2002-2011).The indicators(pH, Electrical conductivity,Total Hardness, ca Hardness, Mg Hardness, Alkalinity, Phenol Alkalinity) in five dams (Balloran,
16 Tishreen, Al-thawra, Al-safarkia and Al-hweez) were studied. The resultsshowed thatpH, Electrical conductivity,Total Hardness, Alkalinity, Phenol Alkalinity, were within the allowed limits according to Syrian standards for drinking and irrigation water and which indicate the presence of pollution water sources.
The research has been conducted in different sites in lattakia, Alhamra and alsabahia
villages of Rabea and Aen alzarqa of Mashqeta. 14 cases of precipitation was marked
which caused runoff and water erosion of soil during the research (seasonal ra
infall in
2011/2012). Samples of rain water of every precipitation case were collected. by using rain
gauges that were installed in the research sites. After that, samples were moved to the
laboratory. The pH was determined after that the samples were analyzed by using an ion
chromatography device(IC).
Water sources in Syrian coastal area have a great importance due to the variety of the
sources and the urgent needs to water for drinking and irrigation. Therefore great efforts
are made to protect water sources from contaminants. This research aim
ed to study some
contaminant indicators in some drinking water sources in the Syrian coastal area. The
study included determining the concentrations of nitrates, nitrites and some heavy metals
including lead, cadmium and zinc in water samples taken from five sources of water
distributed from north Lattakia to north Tartous. The results showed that the concentrations
of nitrate, nitrite and heavy metals differ depending on the water source. However, all
these concentrations were lower and within the acceptable limits of Syrian standard for
drinking water. The study concluded that water resources in the coastal area are
distinguished with their relative purity and contaminants little reach.
Our study shows that only 31 % of the world issue the chemical periodicals
/1058/. Out of the 1058, 92 % are issued by the third of these countries (20
countries which is equal to 10 % of the world), in which the number of refereed
periodicals is
higher than the unrefereed ones. The ratio was the same when the
periodicals were categorized by the spoken language.
The research aims to complete the theoretical, analytical and practical study for
elevation networks in some medium and small dams in the coastal region of the Syrian
Arab Republic, In terms of the configuration of network, strength of network and
measured
elements, And instruments that must be used to obtain the required accuracy, and efficient
of the mathematical model used, The design and implementation of monitoring and control
points in the used network and propose appropriate solutions. During the research was
done on two independent programs , The first relates to simulated measurements in the
elevation network specific elements, The second for adding program to software is the
famous engineering drawing (land development) to enable the user for adjusting elevation
networks without going out of the graphical program.
The research concluded that specific proposals on elevation geodetic networks
studied, and to show the efficiency of all programs designed within Land development
software and modeling the elevation measurements.
