هدف البحث إلى دراسة حركية جماعات الجراثيم الزرقاء في بحيرة سد الروم بالـسويداء جنـوبي سورية، حيث ترتبط بنوعية المياه و تأثير الظروف البيئية في الفصول المختلفة من السنة، و إلى تعريـف الأجناس الموجودة حيث بلغت 17 جنساً، درست تغيراتها الشهرية على مدى عام كامل، و حسبت الكتلـة الحيوية لأهم الأجناس السائدة، و كانت ذروة الازدهار في تشرين الأول، و في تموز بلـغ معامـل التنـوع أعلى قيمة في بحيرة سد الروم، في حين لم تزدهر الجراثيم الزرقاء في بحيرة سد جويلين.
This research aims to study dynamics cyanobacteria population in the Room reservoir (in the south Syria: Sweeda), which affected by water quality environmental conditions, and seasonal. 17 genera where identified and their dynamics studied monthly during 2007, calculate the biomass of the prevail genera. The bloom was occurred in October, and the value of diversity coefficient was the highest in July in the Room reservoir, but didn't occurred in the Jouelen reservoir.

This research aims at studying the most important indicators of water pollution leading to
nutrient increase (eutrophication) in AL- Basel Dam Lake, and connecting them with
pollution sources represented by untreated sewage water and agricultural d
rainage water,
including rain water coming from the lands surrounding the lake. Among the most
important of these indicators are total phosphorus (TP) and total Nitrogen (TN). Samples
were taken and analyzed from four sitesof the lake (S1, S2, S3, S4) were conducted
periodically. The work continued to conduct tests for full hydrological cycle as of January
(2016) until December (2016). The study showed that the lake was highly fertilized
according to the (TN- TP) this indicates that the lake is affected by the pollutants it
encounters, especially the wastewater pollutants. The specific component of algal growth
was determined by knowing the ratio between total nitrogen and total phosphorus. The TN
/ TP ratio was greater than 10, so total phosphorus is the specific component of algal
growth in the Basel DamLake.
The research aims to determine the water Quality Index for the Lake of 16 Tishreen Dam. To achieve
this aim, we have carried out different periodical physic-chemical and bacterial measurements on the lake
water. The samples were taken at five sites
along the lake for a period of one complete year. The indicators
that have been measured are: Temperature, Turbidity, PH, EC, DO, BOD5, NO3, NO2, NH4 ,PO4, F.C.
Measurement results were represented diagrammatically, and compared with the Syrian Specification
Standards for portable Water. The lake was classed according to these Indices: Malays quality index,
Canadian Indices (NSFWQI), (NEWWQI). The Lake was Classed according to these indices as following:
from third grade at all locations (Malays Index), from second grade at the middle lake and from a third grade
to all other locations (NSFWQI), and from second grade at all locations (NEWWQI). According to this
indices the water is not good for drinking and needs treatment. The Productivity of the lake was determined.
The Lake is Eutrophic according to TN,TP in the middle but Hypertrophic according to TN,TP in all other
locations.

Resulting backwash water from existing filters, in the water purification plants, is actually thrown in most
cases in water bodies, valleys or discharged into other system without making any benefit from it.
The amount of backwash water is well est
imated to be in average (3-4%) of purified water amount. Even
if this amount is generally not relevant, it can however be considered to be useful in some circumstances,
where the source water is rare or there is no water resource in the region at all.
Treatment of backwash water depends on the reuse need of it, either for drinking or irrigation purposes,
so that the treated water must be in accordance with the water quality standard stated in related
specifications.
In this research, the resulting backwash water purification plant at Roum Dam near Swaida town has
been scientifically analyzed and treated in a plant designed and built for this purpose.
In this paper, the results of experiments are discussed; important facts have been concluded and
economic feasibility for water reuse was determined.
The study included 144 Free – living fish from the Lake of 16 Tishreen Dam, collected randomly during the period from 12/2011 until 11/2012, on monthly basis to detect the infection with Epistylis sp. and determine its distribution rate.
Fish sam
ples were: Cyprinus carpio L., Varicorhinus damascinus, Garra rufus, Tilapia zilli, and Liza abu. Tilapia zilli was the most prevalent in the lake of 16 Tishreen Dam.
The study revealed fish infection with Epistylis sp. on free – living fish in the Lake, with a total infection rate 22.22 % , mainly on Tilapia zillii (29.70 %) and then on mullet (2%);No infection with Epistylis sp. Was recorded on the other fish species. The infection with this ecto Epistylis sp. was recorded for the first time in Syria in our study.
The infection with Epistylis sp. was located on the skin, fins and gills. The highest infection rate was on the fins ( 42.34 %) , followed by skin (37.46 %) , and then by gills (1.87 %) .
The infection with Epistylis sp. had the highest rate in summer ; i.e. during high temperature , low concentration of dissolved oxygen , and slightly high value of BOD.
The study showed that, the water of 16 Tishreen Dam is relatively clean.
