The research study scenarios water hammer problem that may cause the destruction of the irrigation pipes, pumping stations and equipmen and part of the irrigation project in terms Ain Beida and its environs in the north-eastern city of Latakia, where the project seeks to quench 5,000 hectares of land with water pumped from Lake Dam November 16 occurrence . It consists of four pumping stations in addition to major irrigation systems and irrigation systems subsidiary. Used in these stations pipes made of steel (Steel) , The reservoir project's main reservoir is two. Bently and Water CAD V8 XM Edition we have in this research with the help of the CD-networking program Modeling of these stations to save time and effort in the study, are HAMMER V8 XM Edition Determine Adhamiya pressures and velocities in the case of runoff stable, identifying pressures Adhamiya in the case of the flow is stable through the development scenario of a water hammer caused by the sudden closure of the valve irreversibility thus leading larger than the carrying capacity of pipes and fittings have a high pressure values, and put another scenario shows the effect of non-use non-return valve in the water hammer occurs, and its role as a good protection of them Thus leading to high pressures and dangerous far greater than the carrying capacity of the pipe fittings values, and also used the compressed air reservoir in the third scenario means other protection from water hammer, and we found through Adhamiya pressures resulting values that the compressed air tank means better protection; it has to prevent any increase in pressure values Adhamiya when water hammer occurs, and kept her on the values that were in the case of steady flow.

Research summary
يتناول هذا البحث مشكلة المطرقة المائية وتأثيرها على شبكات أنابيب الري ومحطات الضخ في مشروع ري هضبة عين البيضاء في شمال شرق اللاذقية. يهدف المشروع إلى ري 5000 هكتار من الأراضي باستخدام مياه من بحيرة سد 16 تشرين. يتكون المشروع من أربع محطات ضخ وشبكات ري رئيسية وفرعية. تم استخدام أنابيب فولاذية في هذه المحطات، والخزان الرئيسي هو خزان قسمي. باستخدام برامج Water CAD وWater Hammer، تم تحديد الضغوط الأعظمية والسرعات في حالتي الجريان المستقر وغير المستقر. تم وضع آليات مختلفة لدراسة تأثير الإغلاق المفاجئ لصمام التحكم وعدم استخدام صمام عدم الرجوع، بالإضافة إلى استخدام خزان هواء مضغوط كوسيلة حماية. أظهرت النتائج أن خزان الهواء المضغوط هو الوسيلة الأفضل للحماية من المطرقة المائية، حيث منع أي زيادة في الضغوط الأعظمية وحافظ على قيمها في حالة الجريان المستقر.
Critical review
دراسة نقدية: بالرغم من أن البحث يقدم دراسة شاملة ومفصلة حول مشكلة المطرقة المائية وتأثيرها على شبكات الري ومحطات الضخ، إلا أنه كان يمكن تحسين الدراسة من خلال تضمين المزيد من البيانات الفعلية من الموقع وتحليلها بشكل أعمق. كما أن الاعتماد الكبير على النمذجة الحاسوبية قد يقلل من دقة النتائج إذا لم يتم التحقق من صحة النماذج باستخدام بيانات ميدانية. بالإضافة إلى ذلك، كان يمكن توسيع الدراسة لتشمل تأثيرات بيئية واقتصادية أوسع للمطرقة المائية على المشروع والمناطق المحيطة به.
Questions related to the research
  1. ما هي مشكلة المطرقة المائية وكيف تؤثر على شبكات الري ومحطات الضخ؟

    المطرقة المائية هي ظاهرة تحدث نتيجة التغير المفاجئ في الضغط أو سرعة الجريان في الأنابيب، مما يؤدي إلى توليد أمواج اهتزازية ارتدادية تسبب ضغوطًا عالية قد تؤدي إلى تدمير الأنابيب والتجهيزات.

  2. ما هي الآليات التي تم استخدامها في البحث لدراسة تأثير المطرقة المائية؟

    تم استخدام ثلاث آليات رئيسية: الإغلاق المفاجئ لصمام التحكم، عدم استخدام صمام عدم الرجوع، واستخدام خزان هواء مضغوط كوسيلة حماية.

  3. ما هي النتائج الرئيسية التي توصل إليها البحث؟

    أظهرت النتائج أن خزان الهواء المضغوط هو الوسيلة الأفضل للحماية من المطرقة المائية، حيث منع أي زيادة في الضغوط الأعظمية وحافظ على قيمها في حالة الجريان المستقر.

  4. ما هي التوصيات التي قدمها البحث لتحسين أداء شبكات الري ومحطات الضخ؟

    أوصى البحث بضرورة دراسة محطات ضخ مياه الري وشبكات أنابيبها باستخدام برامج متقدمة مثل Water CAD وBentley HAMMER، وتوسيع استخدام البرمجيات الحاسوبية لتوفير الوقت والجهد والتكلفة في وضع آليات الحماية.

The research was conducted at Al- Hassaka province during the 2010 - 2011 season to study socio-economic factors and other factors affecting the decision of wheat farmers to adopt the technology of modern irrigation and to identify the barriers th at limit the adoption of these techniques. Correlation and binary logistic regression was applied for data analysis. The results showed that 77.78% of the total farmers studied were using modern irrigation to irrigate their wheat crops and the rest were using traditional irrigation and this percentage is expected to increase from 77.78% in 2010 to 95% in 2025 with an annual rate of nearly 1.15%. Sprinkler irrigation adopted by larger percentage (63.33%) of farmers who adopted modern irrigation techniques and followed by the developed surface irrigation on lines (11.11%). It was observed that the high cost of the network played a fundamental role in the lack of 42.55% of farmers to adopt modern irrigations Statistical analysis showed that there was an inverse significant relationship between each of independent variables (percentage of farming labor force to total family labor force, farmer's experience) and the dependant variable adoption of modern irrigation techniques but there was a positive significant relationship between adoption of modern irrigation and other independent variables such as, cereals yield, farmers education level and direction of the farmer towards the agricultural extension.
The research aimed at studying the impact of the most important economic and social factors affecting the adoption of new irrigation techniques، namely water collective management in ALGhab basin in Syria .The research accomplished by taking a si mple random sample of 264 farmers .Because of the nature of dependent variable which is dichotomous ،(1= adoption of water collective management،0=otherwise)،The binary logistic regression was used.
The research was carried out during the growing seasons of 2011 and 2012 to study the effect of land leveling by laser, three tillage depths(01, 25 and 35cm) and three irrigation systems with 7, 8, and 9 day intervals, along with the interactive ef fect between them on the yield of cotton (C.V Aleppo-90), irrigation management and net grossing. The study showed the following results: 1- Land leveling by laser significantly increased the seed cotton yield, saved irrigation water, and made net grossing higher as compared to no-leveling by laser through the two seasons. 2- The two depths of tillage (25 and 35cm) significantly increased the seed cotton yield, increased the irrigation water amount, and made net grossing higher as compared to the depth of tillage (10cm).. 3- Increasing the irrigation water amount significantly increased the seed cotton yield which reached 1441KG/H, and achieved higher grossing which reached 31360 S.P/H as compared to the lower irrigation water amount. 4- The interactive effect between the factors of this experiment gave a significant positive difference. The best results were at (deep tillage 35cm × intervals 7 days × leveling by laser) through two seasons.
This study considers the efficiency of irrigation water usage in the economic and productive aspects of peanuts crop in Syrian lands, in particular: mid, coastal and eastern lands, in terms of arithmetic means during the period of 2010-2012.
This experiment was conducted during ١٩٩٦-١٩٩٨ to ivestigate study the effect of using different types of irrigation water on some soil properties and its cotton, corn and wheat productivity under the agroclimatic conditions of Deir Ezzor.
