Evaluation of Reference Evapotranspiration Methods in Arid, Semiarid, and Humid Regions
It is often necessary to find a simpler method in different climatic regions to calculate reference crop evapotranspiration (ETo) since the application of the FAO-56 Penman-Monteith method is often restricted due to the unavailability of a comprehensive weather dataset. Seven ETo methods, namely the standard FAO-56 Penman-Monteith, the FAO-24 Radiation, FAO-24 Blaney Criddle, 1985 Hargreaves, P...

برای برآورد تبخیرتعرق گیاه مرجع (ET0) روش ترکیبی فائو‌ـ پنمن‌ـ مانتیث (F-P-M)، به منزلة روشی استاندارد، جهت ارزیابی نتایج سایر روش‌های تجربی در دو گروه دمایی ]بلانی‌ـ کریدل (B-C) و هارگریوز‌ـ سامانی (H-S)[ و تشعشعی ]جنسن‌ـ هیز (J-H) و تورک (Tc)[ استفاده میشود. در این تحقیق، با استفاده از دادههای ایستگاه هواشناسی کشاورزی هاشمآباد گرگان، واقع در اقلیمی نیمهخشک، مقادیر ET0 برآوردی با مقادیر رو...
متن کاملA Comparative Study of Potential Evapotranspiration Estimation by Eight Methods with FAO Penman–Monteith Method in Southwestern China
Potential evapotranspiration (PET) is crucial for water resources assessment. In this regard, the FAO (Food and Agriculture Organization)–Penman–Monteith method (PM) is commonly recognized as a standard method for PET estimation. However, due to requirement of detailed meteorological data, the application of PM is often constrained in many regions. Under such circumstances, an alternative metho...
متن کاملEvaluation of Reference Evapotranspiration Estimation Methods and Development of Crop Coefficient Models
This study is an attempt to find best alternative method to estimate reference evapotranspiration (ETo) for the Nagarjuna Sagar Reservoir Project [NSRP], command area located at Andhra Pradesh, India. When input climatic parameters are insufficient to apply standard Food and Agriculture Organization (FAO) of the United Nations Penman–Monteith (P–M) method. To identify the best alternative clima...
متن کاملComparison of different empirical methods for estimating ddaily reference evapotranspiration in the humid cold climate (case study: Borujen, Shahrekord, Koohrang and Lordegan)
The proposed method for calculation of potential evapotranspiration is Penman-Monteith FAO method, but there are other methods that require less meteorological data but estimates close to the FAO Penman-Monteith method in different climatic conditions. Performance evaluation of these methods on the same basis is prerequisite for selecting an alternative approach in accordance with available da...
