Abstract

Water is the source of life, so it must be conserved and reduced, especially in the irrigation of agricultural crops in semi-arid countries such as Syria, where water consumption in irrigation of agricultural land amounts to about 80% of the total water resources.

Therefore, water management in irrigation water distribution networks in all its forms and types should be improved to improve the yield of the distribution process and to reduce losses as much as possible by automatically controlling the distribution of water and maintaining fixed water levels near the regulating and distribution systems in these networks.

In this study, a computer mathematical model will be constructed using the C Sharp programming language to solve the gradually varied flow equations in the prismatic channels using the characteristics method with variable nets(CHVN)to determine the best distance between water regulation elements in irrigation channels.

المياه هي مصدر الحياة، ولذلك يجب الحفاظ عليها، وتقليل هدرها وخصوصاً في عمليات ري المحاصيل الزراعية في البلدان شبه الجافة كسوريا مثلاً، حيث يبلغ استهلاك المياه في ري الأراضي الزراعية قرابة 80% من الموارد المائية الاجمالية.

لذلك يجب تحسين إدارة المياه في شبكات توزيع مياه الري بجميع أشكالها وأنواعها، لتحسين مردود عملية التوزيع وتخفيض الفواقد قدر الامكان من خلال التحكّم الآلي بتوزيع المياه والحفاظ على مناسيب ثابتة للمياه بالقرب من أجهزة التنظيم والتوزيع في هذه الشبكات.

تم في هذه الدراسة بناء نموذج رياضي حاسوبي باستخدام لغة البرمجة C Sharp لحل معادلات الجريان المتغيّر تدريجيّاً في الأقنية الموشوريّة باستخدام طريقة المميزات متغيرة الشبكة                                  (characteristics method with variable nets CHVN)، لتحديد التباعد الأمثل بين عناصر تنظيم الجريان في أقنية شبكات الري.
