This study was conducted during the period from 10/9/2016 to 9/9/2017 in Demsarkho
orchards area (Lattakia) on the west coast of Syrian Arab Republic. The study aimed to
identificate "Syrphidae" in this area. Samples were collected by yellow dishes
in weekly
rate. A total of 341 Syrphid flies were collected and they belong to 15 species form 10
genera. The most abundant species was Sphaerophoria scripta (relative abundance
33.43%), followed by Episyrphus balteatus (20.53%), then Melanostoma mellinum
(14.66%).
The study and design of water dams depend essential on prediction of water volumes
or future predicted in rivers, by using the time series analysis of the historical
measurements.
The research aims to make statistical study of monthly water volume
s incoming in
AL-Aroos River in Syrian coastal and future prediction of these volumes. And the
Box-Jenkins models is adopt to analysis the time series data, because of its high accuracy.
We attend the monthly water volumes for 15 years. And after doing the wanted tests on
model residuals we found that the best model to represent the data is SARIMA(0,1,2)
(1,2,1)12 , and after dividing the data to 14 years to build the model and one year to test it ,
and depending on the smallest of weighted mean of criteria RMSE, MAP, MAE,. The best
predicted model is SARIMA (1,1,0) (0,1,1)12 and the model give the nearest predicted of
measured data actually.
A microscopic study was done on five samples from the current beach sand at Ra’asShimra beach in order to identify their Foraminifera content and the abundance of the species relative to each other. The micropaleontology analysis showed that the majo
rity of the 17 specified types live on the bottom in shallow marine waters at moderate to hot temperatures. The abundance of the species was noticed in the benthic species such as: Amphistegina, Textularia, and peneroplis, which indicates the availability of suitable environmental conditions for the prosperity of these species, which is close to the current conditions. The samples of sand studied are characterized by their being disjointed, small to medium in size, varying in color, and rich in organic remains, mainly the remains of molluscs, in addition to oval marine-originated stones that vary in size. The X.R.D analysis showed the presence of two phases: a major calcareous phase, and a secondary quartz phase. The study of the thin rock slides taken from rocks located in the region, which can be considered as the source rocks of sand in the study area, showed that it is a sandy limestone.
This search includes doing an analytical study to show the
outcomes of introduse the Thiessen Polygon method in calculate
the flow out of node in water distribution system ، and doing the
hydraulic calculation based on the new method’s outcomes and
comparing these outcomes with field measurements which
conducted in several control points .
Vertical sampling process took place to Copepoda during the summer and winter of
2009 and 2010 from Alzzouzo castle which is located in the coastal region of Jableh city.
This region has special environmental properties. Sampling was accompanied wi
th
measuring water temperature, salinity, and dissolved oxygen in the water.
The total number of samples studied in all areas of study is 106 samples. 100 species
were identified during the summer, while 89 species were identified during the winter;
most species belongs to the order of Calanoida. It was noted by the study that most species
appeared in two seasons together, while some species appeared in the season without the
other. It was also noted that the abundance of Copepoda was higher in summer with an
average of (5314 individual / m
3), while the average in winter was (4353, 40 individual / m
3).
It was clear from the study that the station near the beach was less diverse and more
prolific than the offshore station during the summer and winter together.
