حوض وادي هريرة إحدى الحويضات اليسرى الرافدة لنهر بردى عند بلدة كفر العواميد، يمتد بمحور شمالي شرقي- جنوبي غربي، على مساحة تقدر بنحو 56 )كم 2، يحده من الشمال حويضة بيسان و حويضات جبال مضايا، و من الشرق ) حويضتا بيسان و وادي مهدي، و يشترك الأخير مع حويضتا أبو سالم و وادي اللوز في رسم الحدود الجنوبية، في حين يشكل نهر بردى الحد الغربي للحوض.
Wadi Huraira Basin is considered one of the left boundary basins to Barada at Kafer Al-Awameed. It extends to an estimated area north-east and south-west about 56 square kilometers. It is bounded Bisan Basin and Madaya Mountains Basin from the from the north, and from the east both of Bisan and Wadi Mahadi Basins; whereas the later shares forming the southern boundaries with both of Abou Salem and Wadi Alawaz; whereas, Barada River forms the western boundary of Wadi Huraira Basin.

The basin of Al-Kandeel Valley represents one of the basins of
western northern area's mountains in the Syrian Arab Republic which is
situated just like the axe in the eastern northern and western southern
direction covering approximately 155km2 w
ith a length rating 20km of
complicated geology character (Structurally & Constructively) where you
can find a variety of surface rocks among of which there are metamorphic
and sedimentary rocks that are of severe dislocation as being subject of
high construction potential imposed by the location of the area under the
aspect of thrust of the Arab plate under the Jurassic plate. Its height is
gradually rating clearly from the eastern northern to western southern.
The values of its local terrain rated between 5 m/km2 in its plain area at
the drain point and 375 m/km2 at the mountain eastern northern area. The
climate prevailing in this area is of seasonal rains and classified under the
Mediterranean Climate (Plain-Mountain).
This research define and study geomorphological properties of the Karstic spring
nameled “Al Gamka” , characterized one of seasonal springs that flux up as “fontain” .
For this issue, we achieved a detailed geological and geomorphological Study in
the
region of spring, in addition to the field measures to draw and define the main karstic paths
and its tributaries, which recharge this spring by groundwater coming from north-east side.
To show the changes happened to the spring path, and to control water level variations
inside this karstic paths and tributaries and the relation with groundwater influx periods
through this “fountain”.
This study showed reasons that led to groundwater influx through this spring with
high discharge, and the relation between this spring discharge with the amount of
precipitation on the recharge area. Finally, I presented detailed explanation about karstic
extension, Which recharge this spring, in addition to the geomorphological development of
the spring region through previous times.
The objective of this article is describing the changes of the coastline shape during
the time period extended between 1973-2014.
the coastal zone is very special because it occur at the interface between the three
major natural systems at the ear
th surface atmosphere, ocean and land surface.
Geomorphological factors operating in all three of these systems are responsible for
shaping the coastal zone, and the interaction between the three different sets of processes
makes the coastal zone an extremely dynamic one.
At present, a wide range of tools and techniques are available to help us to study the
evolution of coastline during the time intervals determined by the available data, and thus
become our ability to predict future changes.
improve our understanding of the geomorphological processes affect the coastal
zone allow us to minimize their effects, and use this knowledge in the development of
comprehensive coastal zone management planning.
This research define and study geomorphological properties of the Karstic Polje,
located in the southern parts of the coastal area “Beerat Aljerd and Ein alshams rgeons”
For this issue, we have used “ G I S” Technology to clarify properties and pla
ce of
this Polje through construction few of informatics slides that contain different types of
data, showing Karstic Polje limits, dimensions, topography of the region, and situated
Karstic characteristics Blind valleys, sink holes, solution doline, hums. Following, we have
studied the Paleogeogeaphic development of the study area, in addition to the forming
conditions, and Geomorphological periods related with this region.
Finally, This study showed the great hydrology importance, resulted from presence
of this Karstic Polje in the mentioned region, through infiltration of large quantities of rain
water by precipitation with annual average up to 1475 m m. This water moves often
through water bearing formations toward the west, where flow out of the Polje and
contribute in consisting of water storage for the coastal area.
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.
