[ 1 ] - بررسی نفوذپذیری خاک‌های سنگریزه‌ای در زیر و بین درختان پرتقال و زیتون شهرستان فسا
In this study, five infiltration models including Kostiakov, Kostiakov-Lewis, Philip, Soil Conservation Service (SCS) and Horton were fitted to the experimental data using the double rings, and the empirical coefficients of these models were determined. Infiltration experiments were conducted in the gravelly sandy loam soil under and between the olive and orange trees in Fasa city, Fars Provinc...
[ 2 ] - کاربرد تلفیقی شبکه عصبی و روش های محاسباتی جهت تخمین دقیق تر تبخیر-تعرق مرجع
در بسیاری از مسائل آبیاری و زهکشی، هیدرولوژی، محیط زیستی، فرسایش خاک و منابع آب تخمین دقیق تر تبخیر-تعرق اهمیت زیادی دارد. استفاده از شبکه عصبی مصنوعی یکی از روش های تخمین تبخیر-تعرق مرجع می‌باشد. تاکنون در بیشتر مقالات منتشر شده داده های اقلیمی به عنوان ورودی شبکه عصبی جهت تخمین تبخیر-تعرق مرجع مورد استفاده قرار گرفته است. در این تحقیق از تبخیر-تعرق محاسبه شده بوسیله روش های محاسباتی هارگریوز ...
[ 3 ] - The Influence of Using Soil Particles Percentage in Comparison with Geometric Characteristics of Soil Particles on the Accuracy of the Pedotransfer Equations and the Critical Point of SWRC
Soil water retention curve (SWRC) reflects different states of soil moisture and describes quantitative characteristics of the unsaturated parts of the soil. Direct measurement of SWRC is time-consuming, difficult and costly. Therefore, many indirect attempts have been made to estimate SWRC from other soil properties. Using pedotransfer functions is one of the indirect methods for estimating SW...
[ 4 ] - Determining the Optimum Applied Water for Sugar Beet in the Case of Crop Price as a Function of Applied Irrigation Water
Shortage of irrigation water is a major problem constraining in agricultural production in arid and semi-arid regions. Deficit irrigation is one way to cope with water scarcity and increase water use efficiency. Determining the optimum applied water based on economic analysis is a major key to the deficit irrigation strategy. In this study, the required equations were derived to determine the o...
