چکیده
The quantity and quality of drain water in saline soil is changing from operation of irrigation and drainage network to a balance status. It will take a very long time, maybe several years, to reach a balance status. Therefore it is very important to have this kind of knowledge to management and control of drain water, during these times. In this paper, the system dynamics technique was used to simulate the performance of a drainage system in unsteady state condition. In fact the system dynamics technique is one of the object oriented approaches that studies and manages complex feedback systems. The model is capable to predict many hydrological parameters such as water table fluctuation, drainage discharge, drain water salinity and ground water salinity. All above parameters were investigated theoretically and their trends were found to be legible. The model was validated using data collected at a tile drained experimental site irrigated with shallow ground water located at khouzestan, Iran. The results indicated the good agreement between the observed and simulated parameters.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
