تشكل المعالم الأثرية السورية جزء اساسيا من التراث الإنساني, ومن هنا تبرز أهمية الحفاظ على هذه المعالم وعلى الرسالة التاريخية التي تنقلها للأجيال القادمة . ويعتبر انهيار الأبنية لأسباب جيوتكنيكية من أهم أسباب انهيارات الأبنية وخاصة في حالة حدوث الهزات الأرضية. يهدف هذا البحث إلى دراسة السلوك الزلزالي المتبادل بين التربة وبناء واقع في قلب مدينة دمشق القديمة وهو البرج الواقع في الواجهة الشمالية لقلعة دمشق الذي يحاذيه نهر بانياس. وقد تم الأخذ بعين الاعتبار الوضع الجيولوجي والزلزالي لموقع دمشق والمواد المستخدمة في الإنشاء ومواصفاتها الفيزيائية الحالية. وخلص البخث إلى تحديد تأثير السلوك الزلزالي للتربة على الإجهادات والانتقالات المتكونة في البناء وانعكاس وجود النهر القريب على هذا السلوك بالإضافة الى احتمالية ظهور التشققات في البناء.

The objective of this article is describing the changes of the coastline shape during
the time period extended between 1973-2014.
the coastal zone is very special because it occur at the interface between the three
major natural systems at the ear
th surface atmosphere, ocean and land surface.
Geomorphological factors operating in all three of these systems are responsible for
shaping the coastal zone, and the interaction between the three different sets of processes
makes the coastal zone an extremely dynamic one.
At present, a wide range of tools and techniques are available to help us to study the
evolution of coastline during the time intervals determined by the available data, and thus
become our ability to predict future changes.
improve our understanding of the geomorphological processes affect the coastal
zone allow us to minimize their effects, and use this knowledge in the development of
comprehensive coastal zone management planning.
This study was carried out for three years (٣-٥ months every year) during
maximum of aquatic hyphomycetes distribution ( in - Autumn and Winter),
which related with the period of leaves-fall. We studied ٩٠ water samples taken
from Banias River. We
identified ٧٠ species of aquatic hyphomycetes by
investigtion ٨٢٨ spore - isolates taken from water samples. The factors
responsible for the occurrence of different patterns of their distribution have
been determined. Therefore, this work is done for the first time in Syria and
given an important side of ecological and botanical diversity in the waters of
our country.
This study determined total quantity and exchangeable form
concentration of zinc and lead in the agricultural soils in the Banias
region. Soil samples collected from five sites from the north-east of the
thermal station.
This study deals with spatial and temporal distributions of organic and inorganic
phosphorus in sedimentary columns from Al-Kabir Al-Shimaliand Al-Hussain estuaries,
during the period March 2013- February 2014.
Organic phosphorus concentrations ra
nged between (2.0 - 207.6) μg/gin sediments
from Al-Kabir Al-Shimali estuary, and from (1.7 –130.9) μg/gin sediments from
Al-Hussainestuary. Sediment content from inorganic phosphorus ranged between
(12.4 – 371.2)μg / g at sediments from Al-Kabir Al-Shimali estuary, and from
(2.0 - 242.6)μg /g at Al-Hussain estuary. Granular composition of sediments did not play
a significant role in the temporal and spatial distributions of organic and inorganic
phosphorus.
In general, organic and inorganic phosphorus concentrations decreased gradually
from winter to summer, and from surface layers of the sedimentary column towards the
deeper layers.
The ratiobetween inorganic and organic phosphorus increasedfrom river into marine
sediments. In addition, this ratio increased gradually as the sedimentdepthincreased, and
was high in winter and low in summer.
The studied area forms a part of the coastal basin on the east coast of the
Mediterranean Sea located north of Tartous city.The area is bordered by the Mediterranean
Sea from the west. And (jobar,banias, albasia) rivers from north, al Housen river
from the
south. The area covers about (358) km2.
The research aims to find arelationship between rainfall and flow within Mrqiyeh
River Basin, by conducting analytical statistical study using Minitab software, which helps
in completing the measurements are not available, and to predict the river flows depending
on the expected precipitation in the river basin. The study found that the relationship is:Q =
216 + 0.0379 P - 36.8ln (P) + 3.46ln(Q) ,and rainfall reflect 87.2% of the changes that
occur to the flow of the river. The study recommended that need to intensify the river
discharges measurements in order to increase the reliability of their data.
