Apport de l'imagerie satellitale a l'estimation de l'évapotranspiration réelle journalière dans le delta de la Mejerda en Tunisie.

Abstract : This study aims to estimate the actual daily- evapotranspiration (ETR) in the agricultural region of the delta of Mejerda. The approach is based on solving the equation of energy balance at the soil surface, using data from the AVHRR images from NOAA satellite. The results obtained show the interest of our model on a daily scale, with a margin of error that does not exceed 15%. It also appears from this work that remote detecting data with low resolution (1 km²) require higher resolution data from LANDSAT satellites (60m) to improve the spatial distribution of the ETR.
