چکیده
Evapotranspiration is one of the most important elements hydrological cycle. Estimation evapotranspiration imperative for effective forest, irrigation, rangeland and water resources management as well to increase yields better crop management. This study aims evaluate effectiveness Surface Energy Balance Algorithm Land (SEBAL) in estimating coefficient corn Mediterranean region Adana province, Turkey. The Landsat 8 satellite images from March September 2018 were used acquire coefficients respective bands. Then, net radiation flux on earth’s surface heat obtained using incoming-outgoing fluxes albedo, emissivity coefficients, land temperature, plant indicators. Next, sensible calculated by determining hot cold pixels under consideration via atmospheric stability conditions. Finally, maps are plotted. also estimated with respected being To validate outcomes SEBAL algorithm, experimental methods employed calculate values evaluated suitable performance metrics. results showed that generated high agreement FAO Penman-Monteith method registering highest correlation (R = 0.91) lowest error (RMSE 1.14). In addition, registered 0.89, 0.87 0.68 Turk, Makkink Hargreaves methods, respectively. Moreover, manifested an acceptable all methods. value was 0.98). show since algorithm actual acceptable, could be a very convenient method. it easily assimilated into farming systems precision agriculture decision-making higher yield.

Evaluation of SEBAL Model for Evapotranspiration Mapping in Iraq Using Remote Sensing and GIS
Evapotranspiration is one of the major parameter in the hydrologic cycle. Standard measurements of this parameter is quite complex due to various factors such as variation of precipitation amount, spatial variation by latitude and longitude and changes in environment and specific site conditions. Although of this complexity, various methods were developed to estimate actual and potential Evapot...
متن کاملEstimation of Regional Evapotranspiration through Remote Sensing
Models used for the remote estimation of evapotranspiration are evaluated using aircraft observations over two distinct vegetation regimes in southwestern Australia. Single-source models using an empirically determined excess resistance term performed better than a two-source model, which does not require such a parameterization. The mean absolute difference between measured and estimated value...
متن کاملEstimation of Actual Evapotranspiration using Remote Sensing data
Estimation of actual evapotranspiration (AET) and its spatial distribution are important to understanding of catchment hydrology. The AET is driven by net energy available to evaporate water from soil and vegetation surfaces, and to transpirate water from vegetation. However, estimating AET is difficult as the evapotranspiration process involves complex physical and biological processes. It is ...

Crop coefficient values are used to estimate crop evapotranspiration (ETc) for determining irrigation scheduling. Many important crop biophysical properties such as Percentage Vegetation Cover and Leaf Area Index can be estimated from remotely sensed Vegetation Index, in order to quantify real time vegetation growth dynamics. The objective of this study was to understand the effectiveness of ba...
متن کاملEstimation of Evapotranspiration from Fields with and without Cover Crops Using Remote Sensing and in situ Methods
Estimation of actual evapotranspiration (ETa) based on remotely sensed imagery is very valuable in agricultural regions where ETa rates can vary greatly from field to field. This research utilizes the image processing model METRIC (Mapping Evapotranspiration at high Resolution with Internalized Calibration) to estimate late season, post-harvest ETa rates from fields with a cover crop planted af...
