Estimating 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 کاملEvaluating the Methods of Estimating Potential Evapotranspiration in Omidiyeh Town
In order to determine the required water for irrigation it is necessary to calculate the amount of needed water by plant or evapotranspiration. The equations that are used to calculate evapotranspiration are not applying the same climatic parameters and, due to their experimental nature, they are not suitable for all climatic conditions. In the present study in order to compare evapotranspirati...
متن کاملProposal of the Regional Complementary Model for Estimating Actual Evapotranspiration Using Remotely Sensed Data
Brutsaert (1979, 1982) suggested a method for the complementary model taking atmospheric stability into account on the basis of the Monin-Obukhov similarity theory. Katul and Parlange (1992a, 1992b) and the authors (1993) independent ly published the papers on the estimation of latent and sensible heat fluxes including the effects of the atmospheric stabil ity. Parlange and Katul (1992c) actual...
متن کاملA general predictive model for estimating monthly ecosystem evapotranspiration
Accurately quantifying evapotranspiration (ET) is essential for modelling regional-scale ecosystem water balances. This study assembled an ET data set estimated from eddy flux and sapflow measurements for 13 ecosystems across a large climatic and management gradient from the United States, China, and Australia. Our objectives were to determine the relationships among monthly measured actual ET ...
متن کاملVariability in riparian zone potential and actual evapotranspiration
Micrometeorological and hydrological measurements were made over one growing season using automatic weather stations and weighing lysimeters at several locations within a multiple land-use agricultural catchment in Southern Ontario. This paper compares modelled potential evapotranspiration (PET) and measured actual evapotranspi-5 ration (AET) values obtained from the soil weighing lysimeters, a...
