يدرس هذا البحث أهم المشاكل و الظواهر التي يتعرض لها السد في مختلف مراحل الانشاء و الإملاء و الاستثمار و أهم مسببات هذه الظواهر و كيفية معالجتها و كيفية مراقبة السدود و القراءات اللازمة من أجل التأكد من جودة عمل السد حسب المعطيات التصميمية له. و من ثم تمت دراسة سد ركامي بنواة غضارية باستخدام برنامج GEO-Studio و نمذجته و ايجاد قيم الاجهادات الشاقولية الحاصلة في جسم السد عند مستوى تخزين أعظمي و من ثم رسم منحنيات تغير الاجهادات الشاقولية مع الارتفاع في كل من أوجه السد الصخرية و النواة الغضارية و مقارنتها و كذلك كل من منحنيات التشوهات الافقية و ضغط ماء المسام ليتم مقارنة القراءات التي تعطيها منظومة المراقبة و التأكد من عمل السد بالطريقة المثالية.
This research study the cause failure earth dams After that it show the more important problems which dams exposure. During its construction and compassingthe importance causes of this case and how we can processing it , and show also the necessary of earth dams observerand the necessary reportsto showing that the work of dam is good. The research also discusses the analysis of earth dam using the Geo slope program. We have chosen many parameters as total stresses, vertical strain , and pore water pressure to study change of this parameters with elevation in the upstream , downstream , and core of dam and draw the requisite graphsgraphs to compare this design values with reading of observer devices to be sure of typical work of dam. Finaly we showing the results and suggest many recommendations.

Research summary
تتناول هذه الورقة البحثية المشاكل الرئيسية التي تواجه السدود الترابية وكيفية مراقبتها لضمان سلامتها واستمراريتها. تبدأ الورقة بتوضيح أهمية السدود الترابية في تخزين المياه والتحكم في الفيضانات، وتستعرض الأسباب التي قد تؤدي إلى انهيارها مثل الفشل الهيدروليكي، التسرب، والفشل الإنشائي. كما تقدم الورقة دراسة حالة لسد ركامي بنواة غضارية باستخدام برنامج GEO-Studio لتحليل الإجهادات الشاقولية والتشوهات وضغط ماء المسام في جسم السد. يتم مقارنة النتائج النظرية مع القراءات الفعلية من أجهزة المراقبة المزروعة في السد للتأكد من سلامة تصميمه وأدائه. تقدم الورقة أيضًا توصيات لتحسين طرق التصميم والمراقبة لضمان استدامة السدود الترابية.
Critical review
دراسة نقدية: تقدم هذه الورقة البحثية نظرة شاملة ومفصلة حول المشاكل التي تواجه السدود الترابية وكيفية مراقبتها. ومع ذلك، يمكن أن تكون الورقة أكثر فائدة إذا تضمنت دراسات حالة إضافية لسدود أخرى في مناطق مختلفة لتقديم مقارنة أوسع. كما أن التركيز على الحلول العملية والتوصيات يمكن أن يكون أكثر تفصيلاً لتوفير إرشادات واضحة للمهندسين والمشرفين على السدود. بالإضافة إلى ذلك، يمكن تحسين الورقة بإضافة المزيد من الرسوم البيانية والجداول لتوضيح البيانات بشكل أفضل.
Questions related to the research
-
ما هي الأسباب الرئيسية لانهيار السدود الترابية؟
الأسباب الرئيسية لانهيار السدود الترابية تشمل الفشل الهيدروليكي، التسرب، والفشل الإنشائي.
-
ما هو الهدف من مراقبة السدود الترابية؟
الهدف من مراقبة السدود الترابية هو التأكد من سلامتها واستدامتها من خلال رصد القراءات الفعلية ومقارنتها بالقيم التصميمية.
-
ما هي الأدوات المستخدمة في مراقبة السدود الترابية؟
تستخدم أجهزة المراقبة المزروعة داخل السد وخارجه لرصد وتسجيل السلوك الداخلي والخارجي للسد، مثل أجهزة قياس الإجهادات وضغط ماء المسام.
-
كيف يمكن تحسين تصميم السدود الترابية بناءً على نتائج المراقبة؟
يمكن تحسين تصميم السدود الترابية من خلال تحليل البيانات المجمعة من أجهزة المراقبة لتطوير طرق تصميم أكثر دقة وواقعية، مما يساعد في تحسين استقرار وأمان السدود.

Therefore in this paper we will present the stability analysis carried out on the
Dwesat dam with vertical core, its high is 33m, the downstream slope of 1V:2.75H and the
upstream slope of 1V:3.0H. Thickness of the vertical core was varied from 1V:
0.25H to
1V:2.0H, and also present the effect of the varied thickness on slope stability for both
upstream and downstream under three design conditions i.e. during and end of
construction, steady state seepage and rapid draw down by General Limit Equilibrium
Method using GeoStudio software.
It was observed from the analysis that by varying the thickness of vertical core of
earth dam, thinner core up to 1V:1.30H gives more stability and further increase in
thickness of core tends to sharp decline in factor of safety for both upstream and
downstream slope under different design conditions.
The scientific and practical value of this research appears in recognizing the characteristics of the clay soil, which is located in Alnabeck, and used in constructing ALwagar earth fill dam. We will study five samples chosen from the materials site
Hofar ALmlagea and which will be used in constructing ALwagar earth fill dam through which some Geo-geometrical characteristics like (Liquid Limit, Plasticity Limit, plasticity index, Consistency Index, Liquidity Index, Clay activity, collapse degree) will be determined.
Depending on the Results of this study, we used international classifications (Casagrande classification – Unified Soil Classification System) to study the soil of the studied area. We made use of the results of the experimental study to determine the position of soil according to the international classification, and we suggested some solutions to improve the characteristics of the soil which is used in constructing soil dams.
This research dealt with an identification of some problems
that confronting with Extension Agent works in Tartous province.
This research depended on a questionnaire traditional indent in
which data were collected ,through the correspondence with
a
random sample of 224 quid ,and data were analyzed statistically by
using repetition and percentages whereas the majority of the
inspected were basically suffering from lack of financial
motivations, additional wages, adequate transportation, the large
number of rurals who are required to deal with ,the lack of
requirements of the guidance work ,the lack of flexibility to do the
necessary adjustments in the guidance program, and there is so no
freedom to make decisions a pant from the managers of work
.consequently ,the study recommended a set of recommendation
which improve the vitality of guidance work in Tartous , and raise
the status of agriculture agents in front of their guidance audience.
The Dams are large and complex projects, and are generally characterized by the
enormous cost of implementation in some cases, and the length of the implementation
period, are rarely carried out a dam in Syria within the estimated plan which develo
ped his
of the cost and time, this is due to the risks that intercepted projects during the
implementation phase and directly influenced the basic project objectives ( cost and time
and quality).
This research experiences to the reality of the implementation of the late dams,
through undertake a study the risks suffered by the implementation of sector and
influenced the basic objectives of the project (cost - time - quality), through a field survey
study includes more than thirty-five dams in Syria.
For this purpose have been used survey was distributed to a slice of experts and
technicians in the form of dams, has enabled to obtain a list of the risks faced by the
implementation of dams in addition to the assessment, In an attempt to develop a scientific
methodology to analyze and manage the risks of dam projects by assessing the probability
of their occurrence and their impact on the objectives of the project in the event of
occurrence, with introduce a new standard for evaluating a detection / control, As per the
approach to FMEA /Failure Mode and Effect Analysis/ and incorporate logic fuzzy, and
arrange those risks according the Risk Criticality Number (RCN) for each risk early in
order be sensitive to them than we can handled properly with proposing appropriate
response strategies.
This Article addresses the interaction between digital technology and Intellectual Property Law. Despite its obvious benefits, the Internet was and still is a major source of legal obscurity. The one million dollar question is to what extent, if at a
ll, can the law of intellectual property strike the correct balance between innovation and the protection of Intellecual Property Rights? Keeping the concepts of digital liabraries, peer 2 peer systems and second life, answering the previous questions seems to be easirer said than done.
Keeping the above in mind, this Article highlights the legal argument in the United States of America, Canada and the UK. As such, it does focus, unexclusivily, on the Common Law System.
The conclusion we have reached is that any answer could be anticipated to deal with these technological issues from a legal point of view should not be taken as an excuse to hinder the development of business
