استمرت هذه الدراسة ثلاث سنوات و خلال أشهر الذروة (الخريف و الشتاء) في انتشار الفطور المائية المرتبطة بتساقط البقايا النباتية و غمرها في المياه. و قد تم ذلك عبر دراسة ٩٠ عينة مائية أخذت من عدة مواقع على امتداد مجرى نهر بانياس (من مياه حوض نهر بردى). لقد مكنتنا هذه الدراسة من التعرف على التوزع الكيفي و الكمي و البيئي لهذه الفطور. و قد تم تحديد ٧٠ نوعًا من الفطور المنتشرة في هذا الحوض و ذلك عبر دراسة ( ٨٢٨ ) من العزلات الحرة لأبواغ الفطور المذكورة من الماء. كما تم عن طريق تطبيق الأسلوب نفسه (المتبع في تحليل نتائج الفطور المعزولة و المشاهدة من مصادر غذائية مختلفة) تحليل نتائج الدراسة. و تم إلقاء الضوء على أهمية هذه الفطور و انتشارها. بالإضافة إلى مناقشة العوامل المسؤولة عن تواجدها و توزعها و انتشارها. و بهذا استطعنا دراسة جانب مهم من الجوانب المتعددة لدراسة التنوع الحيوي النباتي في بعض من مياه بلادنا مشيرين أثناء ذلك إلى الأنواع الفطرية المائية المسيطرة و الأكثر انتشارًا.
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.

Snobar River is the basic water resource system in Snobar watershed (268.8 km2), which empties into the Mediterranean sea 10 kilometers south of Lattakia. We must find out advanced management to face of the recent serious conflicts such as climate ch
anges. Modeling is adopted as appropriate tool to achieve this object. This study uses the software package WEAP21 (Water Evaluation and Planning System), which is specifically designed to evaluate and plan the water resources. We suggest two scenarios to carry out the weaping Snob arriver basin: the first includes new irrigation techniques, the second includes extended dry climate. The study has shown that demand site coverage reaches to 100%, but the river dries in the downstream of Athwart reservoir. We economize on water by suggestion a dripping irrigation technique (59%). Water year method and extended dry climate scenario declare the likely dangerous effects of climate changes.
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.
In this study the concentration of (Cu, Cr, Cd, Fe, Mn, Ni, Zn , Pb ,V &Co) in
some sedimentary columns and pore-water extracted from the estuary of Al-Kabeer
alshemali river was determined during four seasons .the concentrations of these metals
w
ere determined using atomic absorption spectroscopy (AAS). The columns were cut into
slices with 2cm of thickness ,the pore water at every slice was extracted using
centrifugation (7000 r/min).the results showed that the concentration increased from
surface(deep=0cm, rich of O2) up to the 4cm of deep ,then the concentration decreased in
deeper slices (down of 4cm,deficiency of O2) and the concentration of Fe and Mn from
high ranking ppm. The rest of the items were relatively lower ranking ppb, but Co, Cd and
V were low. meat increased the concentration of all these elements in the spring and
summer, compared with the values in the winter and autumn, due to increasing human
activities on the one hand and the high temperature on the other hand, leading to increased
activities of bacterial that leads to the decomposition of organic material that may increase
the ratios of these elements in the pore water.
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 p
resent 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.
Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some t
aps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. 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 higher pure.
