Assessing Experimental and Intelligent Models in Estimating Reference Evapotranspiration
Introduction: As the most important element in the hydrologic cycle which depends on climate variables such as near-ground wind speed, air temperature, solar radiation, and relative humidity, reference evapotranspiration (ET0) is normally computed through a variety of methods, each of which requires different and in some cases extensive data that are unavailable in many circumstances, especial...
متن کاملEstimating Riparian and Agricultural Actual Evapotranspiration by Reference Evapotranspiration and MODIS Enhanced Vegetation Index
Dryland river basins frequently support both irrigated agriculture and riparian vegetation and remote sensing methods are needed to monitor water use by both crops and natural vegetation in irrigation districts. We developed an algorithm for estimating actual evapotranspiration (ETa) based on the Enhanced Vegetation Index (EVI) from the Moderate Resolution Imaging Spectrometer (MODIS) sensor on...
متن کاملEstimating Reference Evapotranspiration for Irrigation Management in the Texas High Plains
Accurate estimates of daily crop evapotranspiration (ET) are needed for efficient irrigation management in regions where crop water demand exceeds rainfall. Daily grass or alfalfa reference ET values and crop coefficients are widely used to estimate crop water demand. Inaccurate reference ET estimates can hence have a tremendous impact on irrigation costs and the demands on freshwater resources...
متن کاملComparison of Artificial Neural Network and Physically Based Models for Estimating of Reference Evapotranspiration in Greenhouse
Evapotranspiration (ET) is one of the major components of hydrologic cycle. Accurate estimation of this parameter is essential for studies such as water balance, irrigation system design and management, and water resources management. Generally we used climate data for calculating evapotranspiration from indirect methods. This study investigates the utility of artificial neural networks (ANNs) ...
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...
