يأتي هذا البحث في إطار دراسة تتناول مجمعات رخويات المياه العذبة في جنوب سورية، الهدف منه تحديد أنواعها و توزعها. و قد أظهرت الدراسة وجود عشرة أنواع في مياه الينابيع و الجداول الواقعة في السفح الشرقي لجبال الحرمون. تنتمي تسعة منها إلى صف بطنيات القدم Gastropoda و نوع واحد إلى صف ذوات المصراعين Bivalvia.

قمنا في هذه الدراسة، و من خلال عينات من الرخويات، جمعت من القطاعات المختلفة لمحافظة ريف
دمشق، بالتعرف على مجمعات أنواع الرخويات الأرضية المنتشرة فيها و قد سجلنا وجود ثمانية أنواع
تنتمي إلى فصائل أربع:
اثنان ينتميان إلى فصيلة Enidae و نوع ينتمي إلى
فصيلة Leucochroeidés و أربعة أنواع تنتمي إلى فصيلة
Helicidae و نوع ينتمي إلى فصيلة Helicellidae.
Six water stations were chosen along the lower reach section of AlKebir ALShimaly
river and some of it's tributaries, differing in their biotic and abiotic features. Water and
animal samples were collected bimonthly during spring, summer & autumn a
nd monthly
during winter during the period 25/8/2013 – 26/8/2014.
Seventeen species of freshwater molluscs were identified in all stations, fifteen
belonging to Gastropoda (6 of Prosobranchia & 9 of Pulmonata) and 2 belonging to
Bivalvia, one of it (Corbicula fluminea) was recorded for the first time in Syrian Arab
Republic.
We focused on in this study on the station ( Mafraq Quesmeen) that we studied it's
chemical and physical properties of the water and we identified 11 mollusc species and the
most frequency of it was Melanopsis praemorsa and it's frequency rate was 46.48% and it
was the most constant in all continuous samples and it was 100%
When estimating groundwater recharge in karstified and fractured aquifers
it’s important to take into consideration, that they differ from porous aquifers
by inhomogeneities of their hydraulic properties because of the great variance
of infiltrati
on properties in their rocks. In this research the process of
groundwater recharge in Sher-mansour and Haramon areas in Antilebanon,
where karstified and fractured aquifers are developed, was discussed. The
portion of rainfall reaching the groundwater was calculated by applying water
balance and groundwater level changes methods. In the first method the area
was divided into surface zones and water balance components were calculated
in each zone and the portion was estimated at 55.8% of rainfall in dry years
like 2005-2006. In the second method the area was divided into subsurface
zones and groundwater level fluctuations, storage coefficient and groundwater
storage were calculated. The groundwater recharge varied between 17.5% in
Haramon area and 80% in Sher Mansour area. The results showed that
portions of rainfall reaching groundwater are not equal in the deferent
subsurface zones and are deferent from those calculated by water balance
method.
This research was carried out during the period 08/28/2012 - 07/29/2013 in order to
determine the qualitative composition of Puffer Fishes (Tetraodontidae) in the marine
water of Latakia.
Fish samples were collected from three stations (Borj Islam
, Al madina al riyadiah
and Jableh), the total of fishes were / 255 / individuals. All fish individuals were classified,
preserved and placed at the High Institute of Marine Research Laboratory, some biological
factors of the collected fish (K%, GSI%,HIS%) were studied.
Results had revealed the presence of five species of Puffer Fish belong to three
genera of Tetraodontidae: Lagocephalus sceleratus, L. spadiceus, L. suezensis,
Sphoeroides pachygaster, Torquigener flavimaculosus. S. pachygaster species (migratory
species from the Atlantic Ocean to the Mediterranean Sea) has been recorded for the first
time in the marine water of Syria. Results showed that L. suezensis were more coincidence
species in the catch. The amounts caught of Puffer Fishes varied according to the stations;
the highest was in Borj Islam. K% was almost similar in all species, while GSI% and
HSI% varied according to the species and seasons.
The problem of drinking water scarcity exacerbates in some villages in Tartous
governorate making water conservation a priority. The aim of this study is to identify
the patterns and practices of household water consumption of a sample of water
su
bscribers in Tartous governorate in order to determine the procedures through which
to rationalize the consumption of drinking water. For this purpose, a survey of 150
household water subscribers was conducted. The answers were then subjected to a
statistical analysis. The results indicated the presence of a high percentage of those who
follow the procedures for rationalizing the consumption of water within the sample
(95.3%), and a low percentage of those who have the techniques for reducing water
consumption (4.7%). The majority of those surveyed (87.3%) objected to increasing the
price of water as a measure to reducing water consumption. The study revealed that
there is a good aqueous awareness in the governorate on which one can rely in
rationalizing the consumption of drinking water through awareness campaigns.
