در حالت کلی معادلات دیفرانسیل با مقادیر اولیه را نمی توان دیفرانسیل می توان جواب طیف وسیعی از مسائل کاربردی را مشخص نمود با روش های تئوری حل نمود، لذا با حل عددی معادلات یک حالت خاص از مسأله مقدار اولیه، مسأله ای به فرم: y^=f(x,y) , y(a)=?, y^ (a)=?^^ است که مشتق اول در آن ظاهر نمی شود. این معادلات طیف وسیعی از پدیده های اطراف ما را شامل می شود، مثلاً معادلاتی که دارای جواب نوسانی هستند از ...

There is a close connection between saltwater intrusion into aquifers and groundwater extraction. Freshwater extraction in coastal aquifers is one of the most important reasons for the saltwater intrusion into these aquifers. Condition of extraction system such as well depth, discharge rate, saltwater concentration and etc. could affect this process widely. Thus, investigating different extract...
