چکیده

محدود بودن توان منابع آب در کشورمان، حفاظت و بهره برداری بهینه از آن را به منظور تأمین نیازهای آبی آیند گان طلب می کند و دستیابی به این اهداف جز با تهیه بیلان منابع آب و ارزیابی پتانسیل آن امکان پذیر نمی باشد. هدف این پژوهش، برآورد پارامترهای بیلان با استفاده از روش توزیعی می باشد. در این راستا پس از بررسی مدل ها و روش های توزیعی موجود در دنیا، مدل شبه توزیعی QDWB (Qausi Distributed Water Balance model)در محیط برنامه نویسی متلب توسعه داده شد. برای اجرای این مدل لازم است تا داد ه های مورد نیاز (بارندگی، تبخیروتعرق پتانسیل، داده های کاربری و خاک و اطلاعات مرتبط، ضرایب تصحیح رواناب و نفوذ) به صورت توزیعی و در قالب سلول‌های 500 در 500 متر در سطح حوضه تهیه شده و به صورت لایه های جداگانه و به فرم ماتریسی به مدل وارد شود. مدل برای تخمین رواناب و نفوذ عمقی، معادله بیلان آب های سطحی را حل می کند و نیاز آبیاری را بر اساس تامین کمبود رطوبت خاک تخمین می زند. محدوده مطالعاتی مورد نظر در این تحقیق حوضه آبریز نیشابور- رخ با مساحت 9157 کیلومتر مربع است. بررسی روابط میان عوامل بیلان مانند مقایسه بارندگی- تبخیروتعرق، بارندگی- رواناب، بارندگی– نفوذ حاکی از این مطلب است که مدل به خوبی فرایندهای هیدرولوژیکی حاکم بر حوضه را درک کرده است. نتایج تبخیروتعرق مدل توسعه یافته حاضر با نتایج مدل SWAT مقایسه شد که نشان دهنده روند مشابه تبخیروتعرق محاسبه شده توسط هر دو مدل می باشد

چکیده [English]

Limitation of water resources in Iran motivates sustaining and preserving of the resources in order to supply future water needs. Fulfilling these objectives will not be possible unless having accurate water balance of watersheds. The purpose of this study is to estimate the water balance parameters using a distributed method. The large number of distributed models and methods was studied and “Quasi Distributed Water Balance model” (QDWB) was written in the MATLAB programming environment. To conduct this model, it is needed that each data layer (precipitation, potential evapotranspiration, land use, soil data,..) to be converted into grid format. In this research the 500m * 500m cell size was used and water balance parameters for each cell was estimated. Runoff and deep percolation obtained from surface balance equation and irrigation needs were estimated based on soil moisture deficit. The study area of 9157 square kilometers is Neyshabour- Rokh watershed. The results showed there is a good correlation between water balance parameters such as precipitation-runoff, precipitation-evapotranspiration, and precipitation- deep percoulation and demonstrate that QDWB model is consistent with the basin hydrological process.Change in soil moisture at basin wide is 1 MCM in 1388-89 and 40 MCM in 1380-81. The evapotranspiration results from a distributed model” SWAT” and QDWB model were in good agreement.
