Abstract

Cyprus now day is facing the problem of drought and as the years go it becomes even bigger. For this purpose it creates the need for a rational and sustainable water resource management. This problem has been treated through the estimation of evapotranspiration using various systematic data. The remote sensing contributes to assessment using both satellite and meteorological data. Also, applying the method of sensing, the objective of this study is to estimate the crop evapotranspiration. This was achieved through complicated equations and models that required the use of several meteorological parameters such as the method of Penman Monteith by FAO adapted to satellite data, which was used in the research. This method was tested as the most accurate estimation of the real evapotranspiration. To achieve this objective were used satellite data, which were collected from the satellites Landsat 5 ET and 7 ETM+ and also from the meteorological data from the meteorological station of the Larnaca airport. At the beginning NDVI and LAI were calculated for the completion of the study, and afterwards they had carried out their correlation. Finally, through the method of Penman-Monteith by FAO the related results were taken, which are the creation of evapotranpspirations‟ maps.
