يعاني حوض بردى و الأعوج من محدودية موارده المائية، مقابل نمو في النشاطات البشرية نتيجـة التزايد السكاني، و من التغيرات المناخية المؤثرة في حجم الهطولات السنوية، و من ثم في الميزان المائي. هدفَ هذا البحث إلى تحديد العجز المائي الحالي و المتوقع في حوض بردى و الأعـوج خـلال المرحلـة الواقعة بين عامي 2012 – 2035 ، و إمكانية تغيره تبعاً لازدياد الفجوة بين العرض و الطلب، و إبراز دور الإدارة المتكاملة للمياه الجوفية في مواجهة التحديات المائية و من ثم تخفيض مقدار العجز المـائي، مـع الأخذ بالحسبان استدامة الأنظمة البيئية كعنصر رئيس من عناصر الإدارة المتكاملة للموارد المائية.
Barada and Auvage basin, experience of limited water resources against growing of human activities related to increasing of inhabitants, and climate changes influence on precipitation and water balance. This research focuses on the definition of present and expected water shortage in Barada and Auvage basin within the period between 2012-2035 year, and the abilities of its changes regarding the increasing of the gap between supply and demand, and the role of integrated groundwater resources management in facing water challenges, so decreasing of water shortage, taking into account, sustainability of ecosystems, as an important element of integrated water resources management.

The contamination of groundwater with nitrates is a common problem in many countries of
the world, especially the agricultural ones where the pollution originates in these countries
mainly from the use of excessive fertilization in agricultural are
as, industrial waste,
sewage, animal dung, and the "installation of air nitrogen by plants, the nitrogen
compounds that arise due to some industries and vehicle emissions which are deposited on
the ground in solids.
The nitrate compounds are carcinogens and hazardous to human health If they were in
high concentrations. The risk of this turning into nitrite nitrate uptake by the bacteria,
especially in the abdomen which in turn causes what is known as Balmithmoglubenemea
in infants and pregnant women (Infant disease blueness). It can also cause stomach cancer
in adults through its interaction with amines and amides in the abdomen, forming
carcinogens (Alntrozzomedat and Alentrzoaminat). Therefore, you must apply the
foundations of the integrated management of groundwater in the study area to maintain
low levels of nitrate in groundwater used for drinking and irrigation.
Groundwater Samples were collected from seven locations distributed in
Lattakiabasin during the winter and summer seasons of 2013.All samples were treated
chemically and calculated statistically to evaluate the quality of the studied water and its
chemical properties. The aim was to assess the suitability of the water to be potable and to
determine the predominant hydrogeology status.
It was noticed that the concentrations of the detected major elements were within
allowed limits cited for drinking and irrigation waters. Also, it was found that there were
no sharp changes either in salinity or in geochemical type of the water toward groundwater
movement. Furthermore, the groundwater in the studied locations was largely influenced
by lithological composition of aquatic holder. In general, these waters were found to be
uncontaminated with marine waters with exception of the location called " wall of Al
Mena Al Baida" that is located near the sea. This has been proven by calculation of some
of geochemical proportions. Also, this study proved that the aquatic flows in the different
water holders of Latakia basin have a hydrolytic relationship among them. Consequently,
these flows comprise a uniform aquatic flow with homogenous properties in most of its
parts. The direction movement of this uniform flow was identical to the general decline of
the zone mostly.
This study is considered a newly addition and continuous survey to
Ascomycetes and Basidiomycetes which are importance in Barada basin
(Damascus district), it basically aims at knowing fungal biological communities
at framework of biodiversity and
ecological diversity in Syria. The study
extended from ١٩٩٦ to ١٩٩٩ years.
Researchers in this study confirm that there are representatives of ١٠
families out of which ١٦ genera has been specified which are distributed to ٢٦
species (٢٤ of them have been specified), and representatives of ١٣ families out
of which ١٨ genera has been specified which are distributed to ٢٧ species. The
places of spreading of each of them in its medium, most important
characteristics, which allow to distinguish it have been referred to, as well as to
the main practical importance, which describes it regarding the nutritive value
or to do environmental roles.
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.
Natural changes in the level of ground water through time is gaining great
importance in evaluating the water system and to provide a lot of information about
groundwater movement , which allows the assessment of the water situation public water
l
ayer in the study area .
We adopted our measurements in groundwater levels frequencies on a private
network monitoring hydrogeological She is the author of 26 wells distributed over the
entire area of the region studied were carried out in some measurements for a period of six
years. The study found that groundwater system of climate type (water division line) is
directly linked to seep from rainfall and seepage from canals and irrigation water plays a
significant role in the pose, which is characterized by Baltkareh and periodic quarterly in
the annual changes of the levels, and the stability and balance in the conditions of these
elevations, and the general direction of movement of groundwater will be from the east and
north-east towards the west and southwest and Askew Hydraulic 0.005 a faddish
topographic situation and the general trend of the cracks and fissures in the area.
