A 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 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...
متن کاملEstimation of Evapotranspiration in Fars Province Using Experimental Indicators
The purpose of this study is to determine the evapotranspiration in Fars province that in many studies such as hydrological balance of water, irrigation systems design and management, simulation of product volume and management of water resources is very important. To do this, first, required data such as daily temperature, humidity, precipitation, wind speed, solar radiation pressures, solar r...
متن کاملEstimation Of Reference Crop Evapotranspiration Using Fuzzy State Models
Daily evapotranspiration (ET) rates are needed for irrigation scheduling. Owing to the difficulty of obtaining accurate field measurements, ET rates are commonly estimated from weather parameters. A few empirical or semi–empirical methods have been developed for assessing daily reference crop ET, which is converted to actual crop ET using crop coefficients. The FAO Penman–Monteith method, which...
متن کاملتعیین تبخیر- تعرق و ضریب گیاهی خیار با استفاده از میکرولایسیمتر در شرایط گلخانه
Soil and water resources are limited and optimal use of water resources in agriculture requires accurate determination of water consumed by plant species in different circumstances. This situation is necessary more than ever due to fast development of greenhouse cultivation. In this regard, to determine evapotranspiration and crop coefficient (KC) of greenhouse cucumber, two microlysimeters wer...
