Comparability analyses are performed to investigate similarities/differences of the standard precipitation index (SPI) and the reconnaissance drought index (RDI), respectively, utilizing precipitation and ratio of precipitation over potential evapotranspiration (ET0). Data are from six synoptic stations in south Khorasan province in Iran.At the first for calculating SPI, the elevation-precipita...

Recently, Squire & Hopkins (2017) showed any coupled dust-gas mixture is subject to a class of linear “resonant drag instabilities” (RDI). These can drive large dust-to-gas ratio fluctuations even at arbitrarily small dust-to-gas mass ratios μ. Here, we explore the RDI in the simple case where the gas satisfies neutral hydrodynamics and supports acoustic waves (ω2 = cs k 2). The gas and dust ar...

Chandler walnut (Juglans regia cv Chandler) on Northern California Black (Juglans hindsii) and Paradox (Juglans hindsii x Juglans regia) rootstocks were irrigated to achieve two levels of regulated deficit irrigation (RDI) in 2002 thru 2005. The RDI strategy was to maintain high midday stem water potential (MSWP) early in the growing season to favor shoot growth and nut size then gradually decr...

خشکسالی پدیده ای است طبیعی که فراوانی آن در مناطق خشک و نیمه خشک ایران، بویژه و استان فارس بسیار زیاد است. ارزیابی و پایش خشکسالی از نیازهای اساسی برنامه ریزیهای مدیریت کشاورزی و منابع آب برای کاهش اثرات آن به شمار می روند. بدین منظور، استفاده از شاخصهای خشکسالی پیشنهاد می شود. از جمله شاخصهای مزبور می توان به شاخصشناسایی خشکسالی (rdi) اشاره نمود. در این تحقیق، دوره ی بازگشت خشکسالی کشاورزی گند...

خشکسالی مشکلات زیادی را در زمینه های مختلف اجتماعی، اقتصادی و زیست محیطی ایجاد می کند که مهمترین آنها در بخش کشاورزی، کاهش میزان عملکرد محصولات زراعی و باغی میباشد. اهمیت این موضوع زمینه‏ساز تحقیق در این مورد بر روی شاخص rdi به عنوان شاخصی که بیشترین پارامتر بیلان آب خاک را در محاسبات دخیل می‏کند، و از طرفی نیز با محدودیت داده‏های زمینی برداشت شده در منطقه مورد پژوهش سازگاری دارد، گشت. این شاخص...
