تشكل العلاقة بين الهطول المطري_الجريان السطحي إحدى المركبات الأساسية للدورة
الهيدرولوجية للمياه في الطبيعة، كما أنها تشكل واحدة من أكثر الظواهر الهيدرولوجية
تعقيداً و صعوبةً في الفهم؛ و ذلك بسبب كثرة عدد المتغيرات المتضمَّنة في نمذجة
العمليات الفيزيائية و التغير المؤقت في مواصفات الحوض، إضافةً إلى تعدد نماذج
الهطولات المطرية. و تعدُّ نمذجة العلاقة بين الهطول المطري و الجريان السطحي مهمة
جدّاً من أجل التصميم الهندسي و الإدارة المتكاملة للموارد المائية، إضافةً إلى التنبؤ
بالفيضان و درء مخاطره. من هنا تبرز أهمية نمذجة العلاقة بين الهطول
المطري_الجريان السطحي اعتمادا على عدد من المتغيرات التي تؤثر بشكل فعال على
الجريان السطحي، بما يتطلبه الأمر من الحفاظ على هذه الثروة الحيوية.
The relationship between precipitation and surface runoff is one of
the fundamental components of the hydrological cycle of water in
nature and is one of the most complex and difficult to understand
because of the large number of parameters involved in the
modeling of physical processes and the breadth of parmetry and
temporary change in basin specifications. Multiple rainfall models
Modeling the relationship between precipitation and runoff is very
important for engineering design and integrated water resources
management, as well as flood forecasting and risk prevention.
